Significant Accounting Policies

Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation: We are a global leader in advanced semiconductor systems. Our broad portfolio of high-performance memory technologies, including DRAM, NAND Flash, and NOR Flash, is the basis for solid-state drives, modules, multi-chip packages, and other system solutions. Our memory solutions enable the world's most innovative computing, consumer, enterprise storage, networking, mobile, embedded, and automotive applications. The accompanying consolidated financial statements include the accounts of Micron Technology, Inc. and its consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America. Certain reclassifications have been made to prior period amounts to conform to current period presentation. In addition, amounts for certain equipment purchases were reclassified from financing to investing within the statement of cash flows to better reflect the current nature of these transactions and to improve comparability with our industry peers. In the fourth quarter of 2015, we adopted, on a retrospective basis, Accounting Standards Update 2015-03 – Simplifying the Presentation of Debt Issuance Costs. (See "Debt – Retrospective Application of a New Accounting Standard" note.) Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Fiscal year 2015 contained 53 weeks and fiscal years 2014 and 2013 each contained 52 weeks. All period references are to our fiscal periods unless otherwise indicated. Derivative and Hedging Instruments: We use derivative instruments to manage a portion of our exposure to changes in currency exchange rates from our monetary assets and liabilities or future cash flows and to reduce volatility in our earnings caused by changes in interest rates that affect our variable-rate debt. Our derivatives have consisted of forward and option contracts and we have also entered into interest rate swap contracts. We do not use derivative instruments for trading or speculative purposes. Derivative instruments are measured at their fair values and recognized as either assets or liabilities. The accounting for changes in the fair value of derivative instruments is based on the intended use of the derivative and the resulting designation. For derivative instruments that are not designated as hedges for accounting purpose, gains or losses from changes in fair values are recognized in other non-operating income (expense). For derivative instruments designated as cash-flow hedges, the effective portion of the gain or loss is included as a component of other comprehensive income (loss), and the ineffective or excluded portion of the gain or loss is included in other non-operating income (expense). The amounts in accumulated other comprehensive income (loss) from these cash flow hedges are reclassified into earnings in the same line items of the consolidated statements of operation and in the same periods in which the underlying transactions affect earnings. Effectiveness is measured by comparing the cumulative change in the fair value of the hedge contract with the cumulative change in the forecasted cash flows of the hedged item. For the effectiveness assessment of our cash-flow hedges, changes in the time value are excluded for forward contracts. We enter into master netting arrangements with our counterparties to mitigate credit risk in derivative hedge transactions. These master netting arrangements allow us and our counterparties to net settle amounts owed to each other. Derivative assets and liabilities that can be net settled with each counterparty have been presented in our consolidated balance sheet on a net basis. (See "Derivative Instruments" note.) Financial Instruments: Cash equivalents include highly liquid short-term investments with original maturities to us of three months or less that are readily convertible to known amounts of cash. Investments with maturities greater than three months and less than one year are included in short-term investments. Investments with remaining maturities greater than one year are included in long-term marketable investments. The carrying value of investment securities sold is determined using the specific identification method. Functional Currency: The U.S. dollar is the functional currency for all of our consolidated subsidiaries. Inventories: Inventories are stated at the lower of average cost or net realizable value. Cost includes depreciation, labor, material, and overhead costs, including product and process technology costs. Determining net realizable value of inventories involves numerous judgments, including projecting future average selling prices, sales volumes, and costs to complete products in work in process inventories. When net realizable value is below cost, we record a charge to cost of goods sold to write down inventories to their estimated net realizable value in advance of when the inventories are actually sold. Inventories are primarily categorized as memory (including DRAM, non-volatile, and other memory) for purposes of determining the lower of average cost or net realizable value. The major characteristics considered in determining inventory categories for purposes of determining the lower of cost or net realizable value are product type and markets. We remove amounts from inventory and charge such amounts to cost of goods sold on an average cost basis. Product and Process Technology: Costs incurred to (1) acquire product and process technology, (2) patent technology, and (3) maintain patent technology are capitalized and amortized on a straight-line basis over periods ranging up to 12.5 years. We capitalize a portion of the costs incurred to patent technology based on historical and projected patents issued as a percent of patents we file. Capitalized product and process technology costs are amortized over the shorter of (1) the estimated useful life of the technology, (2) the patent term, or (3) the term of the technology agreement. Fully-amortized assets are removed from product and process technology and accumulated amortization. Product Warranty: We generally provide a limited warranty that our products are in compliance with our specifications existing at the time of delivery. Under our general terms and conditions of sale, liability for certain failures of product during a stated warranty period is usually limited to repair or replacement of defective items or return of, or a credit with respect to, amounts paid for such items. Under certain circumstances, we provide more extensive limited warranty coverage than that provided under our general terms and conditions. Our warranty obligations are not significant. Property, Plant and Equipment: Property, plant, and equipment is stated at cost and depreciated using the straight-line method over estimated useful lives of generally 10 to 30 years for buildings, 5 to 7 years for equipment, and 3 to 5 years for software. Assets held for sale are carried at the lower of cost or estimated fair value and are included in other noncurrent assets. When property, plant, or equipment is retired or otherwise disposed, the net book value is removed and we recognize any gain or loss in our results of operations. We capitalize interest on borrowings during the period of time over which we carry out the activities necessary to bring the asset to the condition of its intended use and location. Capitalized interest becomes part of the cost of the underlying assets and amortized over the useful lives of the assets. Research and Development: Costs related to the conceptual formulation and design of products and processes are expensed as research and development as incurred. Determining when product development is complete requires judgment. Development of a product is deemed complete once the product has been thoroughly reviewed and has passed tests for performance and reliability. Subsequent to product qualification, product costs are valued in inventory. Product design and other research and development costs for certain technologies are shared with our joint venture partners. Amounts receivable from cost-sharing arrangements are reflected as a reduction of research and development expense. (See "Equity – Noncontrolling Interests in Subsidiaries – IMFT" note.) Revenue Recognition: We recognize product or license revenue when persuasive evidence that a sales arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. If we are unable to reasonably estimate returns or the price is not fixed or determinable, sales made under agreements allowing rights of return or price protection are deferred until customers have resold the product. Stock-based Compensation: Stock-based compensation is measured at the grant date, based on the fair value of the award, and recognized as expense under the straight-line attribution method over the requisite service period. We issue new shares upon the exercise of stock options or conversion of share units. (See "Equity Plans" note.) Treasury Stock: When we retire our treasury stock, any excess of the repurchase price paid over par value is allocated between additional capital and retained earnings. Use of Estimates: The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires our management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures. Estimates and judgments are based on historical experience, forecasted events, and various other assumptions that we believe to be reasonable under the circumstances. Estimates and judgments may differ under different assumptions or conditions. We evaluate our estimates and judgments on an ongoing basis. Actual results could differ from estimates.

Variable Interest Entities

Variable Interest Entities	12 Months Ended
	Sep. 03, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities We have interests in entities that are VIEs. If we are the primary beneficiary of a VIE, we are required to consolidate it. To determine if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing, and other applicable agreements and circumstances. Our assessments of whether we are the primary beneficiary of our VIEs require significant assumptions and judgments. Unconsolidated VIEs Inotera: Inotera is a VIE because of the terms of its supply agreement with us. We have determined that we do not have the power to direct the activities of Inotera that most significantly impact its economic performance, primarily due to limitations on our governance rights that require the consent of other parties for key operating decisions and due to Inotera's dependence on Nanya for financing and the ability of Inotera to operate in Taiwan. Therefore, we do not consolidate Inotera and we account for our interest under the equity method. (See "Equity Method Investments – Inotera" note.) EQUVO: EQUVO HK Limited ("EQUVO") is a special purpose entity created to facilitate an equipment sale-leaseback financing transaction between us and a consortium of financial institutions. Neither we nor the financing entities have an equity interest in EQUVO. EQUVO is a VIE because its equity is not sufficient to permit it to finance its activities without additional support from the financing entities and because the third-party equity holder lacks characteristics of a controlling financial interest. By design, the arrangement with EQUVO is merely a financing vehicle and we do not bear any significant risks from variable interests with EQUVO. Therefore, we have determined that we do not have the power to direct the activities of EQUVO that most significantly impact its economic performance and we do not consolidate EQUVO. SC Hiroshima Energy Corporation: SC Hiroshima Energy Corporation ("SCHE") is an entity created to construct and operate a cogeneration, electrical power plant to support our wafer manufacturing facility in Hiroshima, Japan. SCHE is a VIE due to the nature of its tolling agreements with us and our purchase and call options for SCHE's assets. We do not have an equity ownership interest in SCHE. We do not control the operation and maintenance of the plant, which we have determined are the activities of SCHE that most significantly impact its economic performance. Therefore, we do not consolidate SCHE. Consolidated VIEs IMFT: IMFT is a VIE because all of its costs are passed to us and its other member, Intel, through product purchase agreements and because IMFT is dependent upon us or Intel for additional cash requirements. The primary activities of IMFT are driven by the constant introduction of product and process technology. Because we perform a significant majority of the technology development, we have the power to direct its key activities. In addition, IMFT manufactures certain products exclusively for us using our technology. We consolidate IMFT because we have the power to direct the activities of IMFT that most significantly impact its economic performance and because we have the obligation to absorb losses and the right to receive benefits from IMFT that could potentially be significant to it. MP Mask: MP Mask is a VIE because substantially all of its costs are passed to us and its other member, Photronics, through product purchase agreements and MP Mask is dependent upon us or Photronics for any additional cash requirements. We have tie-breaking voting rights over key operating decisions and nearly all key MP Mask activities are driven by our supply needs. We consolidate MP Mask because we have the power to direct the activities of MP Mask that most significantly impact its economic performance and because we have the obligation to absorb losses and the right to receive benefits from MP Mask that could potentially be significant to it. (See "Equity – Noncontrolling Interests in Subsidiaries" note.)

Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In July 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-11 – Simplifying the Measurement of Inventory, which changed the subsequent measurement guidance from the lower of cost or market to the lower of cost or net realizable value, with net realizable value defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. No other changes were made to the current guidance on inventory measurement. We adopted this standard in the fourth quarter of 2015. The adoption of this standard did not have a material impact on our financial statements. In April 2015, the FASB issued ASU 2015-03 – Simplifying the Presentation of Debt Issuance Costs , which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, as appropriate, consistent with debt discounts, as opposed to an asset. We adopted this standard in the fourth quarter of 2015 on a retrospective basis. As a result of adopting this standard, we presented our debt issuance costs for recognized debt liabilities as a direct reduction of the related debt liability in the consolidated balance sheets for all periods presented. (See "Debt – Retrospective Application of a New Accounting Standard" note.)

Recently Issued Accounting Standards	Recently Issued Accounting Standards In April 2015, the FASB issued ASU 2015-05 – Customer's Accounting for Fees Paid in a Cloud Computing Arrangement , which provides additional guidance to customers about whether a cloud computing arrangement includes a software license. Under ASU 2015-05, if a software cloud computing arrangement contains a software license, customers should account for the license element of the arrangement in a manner consistent with the acquisition of other software licenses. If the arrangement does not contain a software license, customers should account for the arrangement as a service contract. ASU 2015-05 also removes the requirement to analogize to ASC 840-10 – Leases to determine the asset acquired in a software licensing arrangement. This ASU will be effective for us beginning in our first quarter of 2017 and early adoption is permitted. We are evaluating the effects of the adoption of this ASU on our financial statements. In February 2015, the FASB issued ASU 2015-02 – Amendments to the Consolidation Analysis , which amends the consolidation requirements in Accounting Standards Codification 810 – Consolidation . ASU 2015-02 makes targeted amendments to the current consolidation guidance for VIEs, which could change consolidation conclusions. This ASU will be effective for us beginning in our first quarter of 2017 and early adoption is permitted. We are evaluating the effects of the adoption of this ASU on our financial statements. In May 2014, the FASB issued ASU 2014-09 – Revenue from Contracts with Customers , which supersedes nearly all existing revenue recognition guidance under generally accepted accounting principles in the U.S. The core principal of this ASU is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Including the one-year extension of this ASU provided by ASU 2015-14, we are required to adopt this ASU beginning in our first quarter of 2019; however, we are permitted to adopt this ASU as early as our first quarter of 2018. This ASU allows for either full retrospective or modified retrospective adoption. We are evaluating the timing of our adoption, the transition method we will elect, and the effects of the adoption of this ASU on our financial statements.

MMJ Acquisition [Member]
Business Acquisition [Line Items]
Micron Memory Japan, Inc.	Micron Memory Japan, Inc. On July 31, 2013, we acquired Elpida, now known as MMJ, and a controlling interest in Rexchip, now known as MMT, for an aggregate of $949 million in cash (collectively, "the MMJ Acquisition"). The MMJ Acquisition included (1) the acquisition of MMJ, including its 65% interest in MMT and (2) the acquisition of an additional 24% interest in MMT from Powerchip Technology Corporation (the "MMT Share Purchase"). The MMJ Acquisition was treated as a single business combination because: (1) the two transactions were entered into and closed contemporaneously, and (2) the MMT Share Purchase was negotiated in contemplation of the acquisition of MMJ and its completion was contingent on the closing of the acquisition of MMJ. In 2014, we purchased additional interests in MMT, increasing our ownership interest to 99.5% . (See "Equity – Noncontrolling Interest in Subsidiaries – MMT" note.) The MMJ Acquisition included a 300 mm DRAM wafer fabrication facility located in Hiroshima, Japan, a 300 mm DRAM wafer fabrication facility located in Taichung City, Taiwan, and an assembly and test facility located in Akita, Japan. The operations from the MMJ Acquisition, which are included primarily in our MBU and CNBU segments, include the manufacture of mobile DRAM targeted to mobile phones and tablets and computing DRAM targeted to desktop PCs, servers, notebooks, and workstations. We estimated the provisional fair values of the assets and liabilities of the MMJ Group as of the July 31, 2013 acquisition date using an in-use model, which reflects its value through its use in combination with other assets as a group and we recognized a gain in 2013 of $1.48 billion . In the second quarter of 2014, the provisional amounts recorded in connection with the MMJ Acquisition were adjusted, primarily for pre-petition liabilities, and we recognized a charge in 2014 for these measurement period adjustments. The valuation of assets acquired and liabilities assumed were as follows: Assets acquired and liabilities assumed: Cash and equivalents $ 999 Receivables 697 Inventories 962 Restricted cash 557 Other current assets 142 Property, plant and equipment 935 Equity method investment 40 Intangible assets 10 Deferred tax assets 811 Other noncurrent assets 66 Accounts payable and accrued expenses (409 ) Current portion of long-term debt (673 ) Long-term debt (1,461 ) Other noncurrent liabilities (75 ) Total net assets acquired 2,601 Noncontrolling interest in MMJ 168 Consideration 949 Preliminary gain on acquisition recognized in 2013 1,484 Adjustment for preliminary pre-petition liabilities (33 ) Final gain on acquisition $ 1,451 Our results of operations for 2013 included $355 million of net sales and $46 million of operating income from the MMJ Group's operations after the July 31, 2013 acquisition date. Selling, general, and administrative expenses in our results of operations for 2013 included transaction costs of $50 million incurred in connection with the MMJ Acquisition. The acquisition of MMJ was pursuant to the terms and conditions of an Agreement on Support for Reorganization Companies (as amended, the "Sponsor Agreement") that we entered into in July 2012 with the trustees of the MMJ Companies pursuant to and in connection with the MMJ Companies' corporate reorganization proceedings under the Corporate Reorganization Act of Japan. As a result of the Japan Proceedings, for so long as such proceedings are continuing, the MMJ Companies are subject to certain restrictions on dividends, loans, and advances. The plans of reorganization of the MMJ Companies prohibit the MMJ Companies from paying dividends, including any cash dividends, to us and require that excess earnings be used in their businesses or to fund the MMJ Companies' installment payments. These prohibitions would also effectively prevent the subsidiaries of the MMJ Companies from paying cash dividends to us as any such dividends would have to be first paid to the MMJ Companies which are prohibited from repaying those amounts to us as dividends under the plans of reorganization. In addition, pursuant to an order of the Japan Court, the MMJ Companies cannot make loans or advances, other than certain ordinary-course advances, to us without the consent of the Japan Court. Moreover, loans or advances by subsidiaries of the MMJ Companies may be considered outside the ordinary course of business and may require consent of MMJ's trustees or, in certain cases, approval by the Japan Court. As a result, the assets of the MMJ Companies, while available to satisfy the MMJ Companies' installment payments and other obligations, capital expenditures, and other operating needs of the MMJ Companies, are not available for use by us in our other operations. Certain uses of the assets of the MMJ Companies, including investments in certain capital expenditures and in MMT, may require consent of MMJ's trustees or, in certain cases, approval by the Japan Court. Disposition of certain assets of the MMJ Companies may also require consent of one or more of the secured creditors. Unaudited Pro Forma Financial Information The following unaudited pro forma financial information presents the combined results of operations as if the MMJ Acquisition had occurred on September 2, 2011. The pro forma financial information includes the accounting effects of the business combination, including adjustments to the amortization of intangible assets; depreciation of property, plant, and equipment; interest expense; and elimination of intercompany activities. The historical results of operations of the MMJ Group for the eleven months ended May 31, 2013 included a gain of $1.69 billion for the forgiveness of debt related to liabilities subject to compromise upon approval of the plans of reorganization by the creditors and the Japan Court. No adjustments were made to the unaudited pro forma financial information for this item, consistent with the requirements for preparation of the pro forma financial information. The unaudited pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the MMJ Acquisition occurred on September 2, 2011. For the year ended 2013 Net sales $ 12,494 Net income 3,825 Net income attributable to Micron 3,770 Earnings per share: Basic $ 3.69 Diluted 3.57 The unaudited pro forma financial information for 2013 includes our results for the year ended August 29, 2013, which includes one month of results from the MMJ Group following the closing of the MMJ Acquisition, and the results of the MMJ Group, including the adjustments described above, for the eleven months ended May 31, 2013.

(2) The fair value of Level 2 securities is measured using information obtained from pricing services, which obtain quoted market prices for similar instruments, non-binding market consensus prices that are corroborated by observable market data, or various other methodologies, to determine the appropriate value at the measurement date. We perform supplemental analysis to validate information obtained from these pricing services. As of September 3, 2015 , no adjustments were made to such pricing information. (3) The maturities of our long-term marketable securities generally range from one to four years. Proceeds from sales of available-for-sale securities for 2015 , 2014 , and 2013 were $1.49 billion , $355 million , and $526 million , respectively. Gross realized gains and losses from sales of available-for-sale securities were not significant for any period presented. As of September 3, 2015 , none of our available-for-sale securities had been in a loss position for longer than 12 months.

As of September 3, 2015 , substantially all of our maximum exposure to loss from our VIEs that were not consolidated was the $1.33 billion carrying value of our investment in Inotera. We may also incur losses in connection with our rights and obligations to purchase all of Inotera's wafer production capacity under our supply agreements with Inotera. We recognize our share of earnings or losses from our equity method investees generally on a two-month lag. Our share of earnings for 2015 included $49 million for the net effect of Inotera's full release of its valuation allowance against net deferred tax assets related to its net operating loss carryforward and the resulting tax provision in subsequent periods. Equity in net income (loss) of equity method investees, net of tax, included the following: For the year ended 2015 2014 2013 Inotera $ 445 $ 465 $ (79 ) Tera Probe 1 11 — Other 1 (2 ) (4 ) $ 447 $ 474 $ (83 ) The summarized financial information in the tables below reflects aggregate amounts for our equity method investees. Financial information is presented for equity method investments as of the respective dates and for the periods through which we recorded our proportionate share of each investee's results of operations. Summarized results of operations are presented only for the periods subsequent to the acquisition or through the disposition of our ownership interests.

In 2013, Inotera issued 634 million common shares to Nanya and certain of its affiliates in a private placement at a price equal to 9.47 New Taiwan dollars per share, which was in excess of our carrying value per share. As a result of the issuance, our ownership interest decreased from 40% to 35% and we recognized a non-operating gain of $48 million in 2013. In 2014, Inotera issued 400 million common shares in a public offering at a price equal to 31.50 New Taiwan dollars per share, which was in excess of our carrying value per share. As a result of the issuance, our ownership interest decreased from 35% to 33% and we recognized a non-operating gain of $93 million in 2014. As of September 3, 2015 , we held a 33% ownership interest in Inotera, Nanya and certain of its affiliates held a 33% ownership interest, and the remaining ownership interest in Inotera was publicly held. As of September 3, 2015 , the market value of our equity interest in Inotera was $1.53 billion based on the closing trading price of 23.20 New Taiwan dollars per share in an active market. As of September 3, 2015 and August 28, 2014 , there were gains of $13 million and $44 million , respectively, in accumulated other comprehensive income (loss) for cumulative translation adjustments from our equity investment in Inotera. Since January 2013, we have purchased all of Inotera's DRAM output at prices reflecting discounts from market prices for our comparable components under a supply agreement. In the second quarter of 2015, we executed a supply agreement, to be effective beginning on January 1, 2016 (the "2016 Supply Agreement"), which will replace the current agreement. Under the 2016 Supply Agreement, the price for DRAM products sold to us will be based on a formula that equally shares margin between Inotera and us. The 2016 Supply Agreement has an initial two-year term, followed by a three-year wind-down period, and contemplates negotiations in late 2016 with respect to a two-year extension, and annual negotiations thereafter with respect to successive one-year extensions. Upon termination of the initial two-year term of the 2016 Supply Agreement, or any extensions, we would purchase DRAM from Inotera during the wind-down period. Our share of Inotera's capacity would decline over the wind-down period. In 2015 and 2014, our cost of products purchased from Inotera was significantly higher than our cost of similar products manufactured in our wholly-owned facilities. We purchased $2.37 billion , $2.68 billion and $1.26 billion of DRAM products in 2015, 2014, and 2013 respectively. Tera Probe In 2013, as part of the MMJ Acquisition, we acquired a 40% interest in Tera Probe, which provides semiconductor wafer testing and probe services to us and others. The initial net carrying value of our investment was less than our proportionate share of Tera Probe's equity and the difference is being amortized as a credit to our earnings through equity in net income (loss) of equity method investees (the "Tera Probe Amortization"). As of September 3, 2015 , the remaining balance of the Tera Probe Amortization was $27 million and is expected to be amortized over a weighted-average period of seven years. Based on closing trading prices, the market value of our equity interest in Tera Probe was $32 million as of September 3, 2015 and $41 million as of June 30, 2015 (the other-than-temporary impairment measurement date for our fourth quarter, commensurate with our lag period). We evaluated our investment in Tera Probe and concluded that the decline in the market value did not indicate an other-than-temporary impairment primarily because of the limited amount of time of the decline and historical volatility of Tera Probe's stock price. In the first quarter of 2015, we recorded an impairment charge of $10 million within equity in net income of equity method investees to write down the carrying value of our investment in Tera Probe to its fair value, based on its trading price (Level 1 fair value measurement). We incurred manufacturing costs for 2015, 2014, and 2013 of $90 million , $117 million , and $13 million respectively, for services performed by Tera Probe. Other Aptina: We held an equity interest in Aptina until August 15, 2014. On August 15, 2014, ON Semiconductor Corporation acquired Aptina for approximately $433 million and we recognized a non-operating gain of $119 million based on our diluted ownership interest of approximately 27% . The gain approximated our share of the consideration because the carrying value of our investment had been reduced to zero in 2012, at which time we ceased recognizing our proportionate share of Aptina's losses. Through May 3, 2013, we manufactured components for Complementary Metal-Oxide Semiconductor ("CMOS") image sensors for Aptina under a wafer supply agreement. Subsequent to May 3, 2013, we provided various services for Aptina under a service agreement. For 2014 and 2013, we recognized net sales of $43 million and $182 million , respectively, from products sold to and services performed for Aptina, and cost of goods sold of $37 million and $219 million , respectively. In 2013, we assigned to LFoundry Marsica L.r.l. ("LFoundry") our supply agreement with Aptina to manufacture components for image sensors. (See "Restructure and Asset Impairments" note.)

Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method. (2) Weighted-average imputed rate of 3.7% and 4.3% as of September 3, 2015 and August 28, 2014 , respectively. (3) Amount recorded for 2014 included the debt and equity components. The equity component was reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash. (4) Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the conversion price per share, holders had the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes. 2015 2014 As of Expected Remaining Term (Years) (1) Outstanding Principal Unamortized Discount and Debt Issuance Costs Net Carrying Amount Outstanding Principal Unamortized Discount and Debt Issuance Costs Net Carrying Amount MMJ creditor installment payments 4 $ 1,012 $ (150 ) $ 862 $ 1,369 $ (238 ) $ 1,131 Capital lease obligations 4 792 — 792 911 — 911 1.258% notes 3 323 (19 ) 304 416 (25 ) 391 2022 Notes 6 600 (11 ) 589 600 (13 ) 587 2023 Notes 8 1,000 (12 ) 988 — — — 2024 Notes 8 550 (5 ) 545 — — — 2025 Notes 9 1,150 (12 ) 1,138 1,150 (13 ) 1,137 2026 Notes 10 450 (4 ) 446 — — — 2031B Notes (2) N/A — — — 114 (28 ) 361 2032C Notes 4 224 (27 ) 197 362 (53 ) 309 2032D Notes 6 177 (27 ) 150 344 (60 ) 284 2033E Notes 2 233 (16 ) 217 300 (28 ) 272 2033F Notes 4 297 (33 ) 264 300 (40 ) 260 2043G Notes (3) 13 1,025 (381 ) 644 1,025 (394 ) 631 Other notes payable 4 205 — 205 243 (6 ) 237 $ 8,038 $ (697 ) $ 7,341 $ 7,134 $ (898 ) $ 6,511 (1) Expected remaining term for amortization of the remaining unamortized discount and debt issuance costs as of September 3, 2015 . The expected remaining term of the 2031B Notes was not applicable because the notes were not outstanding as of September 3, 2015 . Expected remaining term for capital lease obligations is the weighted-average remaining term. (2) As holders had elected to convert these notes and we elected to settle the conversions in cash, the net carrying amount for 2014 included the debt component and equity component, which were reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash, resulting in an aggregate liability of $389 million . The outstanding principal reflects the original principal of the 2031B Notes. (3) The 2043G Notes have an original principal amount of $820 million that accretes up to $917 million through the expected term on November 15, 2028 and $1.03 billion at maturity in 2043. The discount is based on the principal at maturity. See "2043G Notes" below. Our convertible and senior notes are unsecured obligations that rank equally in right of payment with all of our other existing and future unsecured indebtedness, and are effectively subordinated to all of our other existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness. Our parent company, Micron, has $5.18 billion of debt (net of unamortized discount and debt issuance costs), including all of our convertible notes and the 2022 Notes, 2023 Notes, 2024 Notes, 2025 Notes, and 2026 Notes, that is structurally subordinated to all liabilities of its subsidiaries, including trade payables. Micron guarantees certain debt obligations of its subsidiaries. Micron does not guarantee the MMJ creditor installment payments. Micron's guarantees of its subsidiary debt obligations are unsecured obligations ranking equally in right of payment with all of Micron's other existing and future unsecured indebtedness. 2015 Debt Restructure In 2015, we consummated a number of transactions to restructure our debt, including conversions and settlements, repurchases of convertible notes, issuances of non-convertible notes, and the early repayment of a note. The following table presents the effect of each of the actions in 2015: Increase (Decrease) in Principal Increase (Decrease) in Carrying Value Increase (Decrease) in Cash (Decrease) in Equity (Loss) Gain (1) Conversions and settlements: 2031B Notes $ (114 ) $ (361 ) $ (389 ) $ — $ (24 ) 2033E Notes (7 ) (6 ) (19 ) (15 ) 2 (121 ) (367 ) (408 ) (15 ) (22 ) Repurchases: 2032C Notes (139 ) (121 ) (415 ) (283 ) (10 ) 2032D Notes (166 ) (140 ) (492 ) (341 ) (11 ) 2033E Notes (60 ) (56 ) (107 ) (49 ) (1 ) 2033F Notes (3 ) (2 ) (5 ) (3 ) — (368 ) (319 ) (1,019 ) (676 ) (22 ) Issuances: 2023 Notes 1,000 988 988 — — 2024 Notes 550 545 545 — — 2026 Notes 450 446 446 — — 2,000 1,979 1,979 — — Early repayment (121 ) (115 ) (122 ) — (5 ) $ 1,390 $ 1,178 $ 430 $ (691 ) $ (49 ) (1) Included in other non-operating expense. Conversions and Settlements : During 2015, we had the following debt conversions and settlements: 2031B Notes : On July 23, 2014, we called for the redemption of our remaining 2031B Notes effective on August 22, 2014. Prior to such effective date, substantially all of the holders of our 2031B Notes exercised their option to convert their notes and, in each case, we elected to settle the amount due upon conversion entirely in cash. These notes were cash settled in 2015. 2033E Notes : During 2015, holders converted a portion of our 2033E Notes, and we elected to settle the amounts due upon conversion entirely in cash. As a result of our elections to settle the amounts due upon conversion in cash, each of the settlement obligations became derivative debt liabilities subject to mark-to-market accounting treatment. Under the terms of the indentures for the above notes, cash settlement amounts for these derivative debt liabilities were determined based on the shares underlying the converted notes multiplied by the volume-weighted-average price of our common stock over a period of 20 consecutive trading days. Therefore, at the dates of our election to settle the conversion in cash, we reclassified the fair values of the equity components of each of the converted notes from additional capital to derivative debt liabilities within current debt in our consolidated balance sheet. Repurchases : During 2015, we repurchased portions of our convertible 2032C Notes, 2032D Notes, 2033E Notes, and 2033F Notes. The liability and equity components of the repurchased notes had previously been stated separately within debt and additional capital in our consolidated balance sheet. As a result, our accounting for the repurchased notes affected debt and equity. Issuances: On April 30, 2015, we issued $550 million in principal amount of 2024 Notes due January 2024 and $450 million in principal amount of 2026 Notes due January 2026. On February 3, 2015, we issued $1.00 billion in principal amount of 2023 Notes due August 2023. Issuance costs for these notes totaled $21 million . (See further discussion in "Senior Notes" below.) Early Repayment : On October 17, 2014, we repaid a note prior to its scheduled maturity. 2014 Debt Restructure In 2014, we consummated a number of transactions to restructure our debt, including exchanges, conversions and settlements, repurchases of convertible notes, issuances of non-convertible notes, and early repayments of notes. The following table presents the net effect of each of the actions: Increase (Decrease) in Principal Increase (Decrease) in Carrying Value Increase (Decrease) in Cash (Decrease) in Equity Loss (1) Exchanges $ 585 $ 282 $ — $ (238 ) $ 49 Conversions and settlements (770 ) (434 ) (1,446 ) (886 ) 130 Repurchases (320 ) (264 ) (857 ) (567 ) 23 Issuances 2,212 2,157 2,157 — — Early repayments (336 ) (332 ) (339 ) — 3 $ 1,371 $ 1,409 $ (485 ) $ (1,691 ) $ 205 (1) $184 million included in other non-operating expense and $21 million included in interest expense • Exchanges : Exchanged $440 million in aggregate principal amount of our 2027 Notes, 2031A Notes, and 2031B Notes into $1.03 billion principal amount at maturity of 2043G Notes. • Conversions and Settlements : Holders of substantially all of our remaining 2014 Notes, 2027 Notes, and 2031A Notes (with an aggregate principal amount of $770 million ) converted their notes and we settled the conversions in cash for $1.45 billion . Holders of substantially all of our remaining 2031B Notes converted their notes in August 2014. As a result of our election to settle the conversion amounts entirely in cash, the settlement obligations became derivative debt liabilities, increasing the carrying value of the 2031B Notes by $275 million in 2014 before being cash settled in 2015. • Repurchases : Repurchased $320 million in aggregate principal amount of our convertible 2031B Notes, 2032C Notes, and 2032D Notes for an aggregate of $857 million in cash. • Issuances : Issued $600 million in principal amount of the 2022 Notes and $1.15 billion in principal amount of the 2025 Notes, and issued $462 million in principal amount of the 1.258% senior notes due 2019. • Early Repayments : Repaid $332 million of notes and capital leases prior to their scheduled maturities. 2013 Debt Restructure During 2013, we repurchased $464 million in aggregate principal amount of our 2014 Notes for $477 million in cash. The liability and equity components of the 2014 Notes had previously been stated separately within debt and additional capital in our consolidated balance sheet. As a result, the repurchase resulted in the derecognition of $430 million in debt for the principal amount (net of $34 million of debt discount) and $15 million in additional capital for the equity component. We recognized a loss of $31 million in 2013, which was included in other non-operating expense. MMJ Creditor Installment Payments Under the MMJ Companies' plans of reorganization, which set forth the treatment of the MMJ Companies' pre-petition creditors and their claims, the MMJ Companies were required to pay 200 billion yen, less certain expenses of the reorganization proceedings and other items, to their secured and unsecured creditors in 7 annual installment payments (the "MMJ Creditor Installment Payments"). The MMJ Creditor Installment Payments do not provide for interest and were recorded at fair value in the MMJ Acquisition. The fair-value discount is accreted to interest expense over the term of the installment payments. Under the MMJ Companies' corporate reorganization proceedings, the secured creditors of MMJ will recover 100% of their amount of their fixed claims in 6 annual installment payments through December 2018 and the unsecured creditors will recover at least 17.4% of the amount of their fixed claims in 7 annual installment payments through December 2019. In December 2014, we paid the second installment payment of 21 billion yen to the reorganization creditors of the MMJ Companies. The secured creditors of MAI were paid in full with a portion of the first installment payment made in October 2013, while the unsecured creditors of MAI will recover at least 19% of the amount of their claims in 7 installment payments through December 2019. The remaining portion of the unsecured claims of the creditors of the MMJ Companies not recovered pursuant to the Reorganization Proceedings will be discharged, without payment, through December 2019. The following table presents the remaining amounts of MMJ Creditor Installment Payments (stated in Japanese yen and U.S. dollars) and the amount of unamortized discount as of September 3, 2015 : 2016 ¥ 19,813 $ 165 2017 19,840 165 2018 19,762 164 2019 28,687 238 2020 33,642 280 121,744 1,012 Less unamortized discount (17,981 ) (150 ) ¥ 103,763 $ 862 Pursuant to the terms of the Sponsor Agreement, we entered into a series of agreements with the MMJ Companies, including supply agreements, research and development services agreements, and general services agreements, which are intended to generate operating cash flows to meet the requirements of the MMJ Companies' businesses, including the funding of the MMJ Creditor Installment Payments. Capital Lease Obligations In 2015, we recorded capital lease obligations aggregating $324 million , including $291 million related to equipment sale-leaseback transactions, at a weighted-average effective interest rate of 3.2% , payable in periodic installments through May 2019. In 2014, we recorded capital lease obligations aggregating $121 million at a weighted-average effective interest rate of 4.6% , payable in periodic installments through December 2023. 1.258% Notes On December 20, 2013, we issued $462 million in principal amount of the 1.258% Notes. The 1.258% Notes mature on January 15, 2019 and are collateralized by certain equipment, which had a carrying value of $95 million as of September 3, 2015 . The principal amount of the 1.258% Notes is payable in 10 semiannual installments in January and July of each year, commencing in July 2014. The Export-Import Bank of the United States (the "Ex-Im Bank") guaranteed payment of all regularly scheduled installment payments of principal and interest on the 1.258% Notes. We paid $23 million to Ex-Im Bank for its guarantee upon issuance of the 1.258% Notes. The 1.258% Notes contain covenants which are customary for financings of this type, including negative covenants that limit or restrict our ability to create liens or dispose of the equipment securing the 1.258% Notes. Events of default also include, among others, the occurrence of any event or circumstance that, in the reasonable judgment of Ex-Im Bank, is likely materially and adversely to affect our ability to perform any payment obligation, or any of our other material obligations under the indenture, the 1.258% Notes, or under any other related transaction documents to which Ex-Im Bank is a party. Cash Redemption at Our Option: At any time prior to the maturity date of the 1.258% Notes, we may redeem the 1.258% Notes, in whole or in part, at a price equal to the principal amount of the 1.258% Notes to be redeemed plus a make-whole premium as described in the indenture, together with accrued and unpaid interest.

These covenants are subject to a number of limitations, exceptions, and qualifications. Cash Redemption at Our Option: We have the option to redeem these notes. The applicable redemption price will be determined as follows: Redemption Period Requiring Payment of: Redemption up to 35% Using Cash Proceeds From an Equity Offering (3) Make-Whole (1) Premium (2) Date Specified Price 2022 Notes Prior to Feb 15, 2017 On or after Feb 15, 2017 Prior to Feb 15, 2017 105.875 % 2023 Notes Prior to Feb 1, 2018 On or after Feb 1, 2018 Prior to Feb 1, 2018 105.250 % 2024 Notes Prior to May 1, 2018 On or after May 1, 2018 Prior to May 1, 2018 105.250 % 2025 Notes Prior to Aug 1, 2019 On or after Aug 1, 2019 Prior to Aug 1, 2017 105.500 % 2026 Notes Prior to May 1, 2020 On or after May 1, 2020 Prior to May 1, 2018 105.625 % (1) If we redeem prior to the applicable date, the price is principal plus a make-whole premium equal to the present value of the remaining scheduled interest payments as described in the applicable indenture, together with accrued and unpaid interest. (2) If we redeem on or after the applicable date, the price is principal plus a premium which declines over time as specified in the applicable indenture, together with accrued and unpaid interest. (3) If we redeem prior to the applicable date with net cash proceeds of one or more equity offerings, the price is equal to the amount specified above, together with accrued and unpaid interest, subject to a maximum redemption of 35% of the aggregate principal amount of the respective notes being redeemed. Convertible Senior Notes Accounting standards for convertible debt instruments that may be fully or partially settled in cash upon conversion require the debt and equity components to be separately accounted for in a manner that reflects a nonconvertible borrowing rate when interest expense is recognized in subsequent periods. The amount initially recorded as debt is based on the fair value of the debt component as a standalone instrument, determined using an interest rate for similar nonconvertible debt issued by entities with credit ratings similar to ours at the time of issuance. The difference between the debt recorded at inception and its principal amount is accreted to principal through interest expense over the estimated life of the note. As of September 3, 2015 , the trading price of our common stock was higher than the initial conversion prices of our 2032 Notes and our 2033 Notes. As a result, the conversion values were in excess of principal amounts for such notes. The following table summarizes our convertible notes outstanding as of September 3, 2015 : Holder Put Date (1) Outstanding Principal Underlying Shares Conversion Price Per Share Conversion Price Per Share Threshold (2) Conversion Value in Excess of Principal (3) 2032C Notes May 2019 $ 224 23 $ 9.63 $ 12.52 $ 161 2032D Notes May 2021 177 18 9.98 12.97 117 2033E Notes February 2018 233 21 10.93 14.21 121 2033F Notes February 2020 297 27 10.93 14.21 154 2043G Notes (4) November 2028 1,025 35 29.16 37.91 — $ 1,956 124 $ 553 (1) The terms of our convertible notes give holders the right to require us to repurchase all or a portion of their notes at a date prior to the contractual maturities of the notes at a price equal to the principal amount thereof plus accrued interest. (2) Holders have the right to convert all or a portion of their notes at a date prior to the contractual maturity if, during any calendar quarter, the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the conversion price. The closing price of our common stock exceeded the thresholds for the calendar quarter ended September 30, 2015 for our 2032 Notes and 2033 Notes; therefore, those notes are convertible by the holders through December 31, 2015. (3) Based on our closing share price of $16.59 as of September 3, 2015 . (4) See "2043G Notes." Carrying amounts of the equity components of our convertible notes, which are included in additional capital in the accompanying consolidated balance sheets were as follows: As of 2015 2014 2032C Notes $ 41 $ 67 2032D Notes 35 69 2033E Notes (excludes $16 and $27 million in mezzanine equity, respectively) 8 3 2033F Notes (excludes $33 and $41 million in mezzanine equity, respectively) 8 1 2043G Notes 173 173 $ 265 $ 313 Interest expense for our convertible notes, consisting of contractual interest and amortization of discount and issuance costs, aggregated $101 million , $132 million , and $156 million for 2015 , 2014 , and 2013 , respectively. Interest expense by note was as follows: Contractual Interest Amortization of Discount and Issuance Costs For the year ended 2015 2014 2013 2015 2014 2013 2032C Notes $ 8 $ 11 $ 13 $ 9 $ 12 $ 14 2032D Notes 9 13 14 6 8 9 2033E Notes 5 5 3 7 7 4 2033F Notes 6 6 3 7 6 3 2043G Notes 31 24 — 13 9 — Other notes (1) — 7 27 — 24 66 $ 59 $ 66 $ 60 $ 42 $ 66 $ 96 (1) Other notes include the 2014 Notes, 2027 Notes, 2031A Notes, and 2031B Notes. 2031B Notes: On July 26, 2011, we issued $345 million of 2031B Notes due August 2031. During 2014, we exchanged $205 million of aggregate principal amount of 2031B Notes for a portion of the 2043G Notes, repurchased $26 million of aggregate principal amount for cash, and called for the redemption of the remaining $114 million of aggregate principal amount effective on August 22, 2014. Prior to such effective date, substantially all of the holders of the 2031B Notes had converted their notes, which were settled in cash with payments of $389 million in 2015. 2032C and 2032D Notes: On April 18, 2012, we issued $550 million of the 2032C Notes and $450 million of the 2032D Notes, each due May 2032. The initial conversion rate for the 2032C Notes is 103.8907 shares of common stock per $1,000 principal amount, equivalent to an initial conversion price of approximately $9.63 per share of common stock. The initial conversion rate for the 2032D Notes is 100.1803 shares of common stock per $1,000 principal amount, equivalent to an initial conversion price of approximately $9.98 per share of common stock. Interest is payable in May and November of each year. During 2015 and 2014, we repurchased $139 million and $188 million , respectively of aggregate principal amounts of the 2032C Notes and $166 million and $106 million , respectively of aggregate principal amounts of the 2032D Notes, for cash. Conversion Rights : Holders may convert their 2032 Notes under the following circumstances: (1) if the 2032 Notes are called for redemption; (2) during any calendar quarter if the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the conversion price of the 2032 Notes (approximately $12.52 per share for the 2032C Notes and $12.97 per share for the 2032D Notes); (3) if the trading price of the 2032 Notes is less than 98% of the product of the closing price of our common stock and the conversion rate of the 2032 Notes during the periods specified in the indenture; (4) if specified distributions or corporate events occur, as set forth in the indenture for the 2032 Notes; or (5) at any time after February 1, 2032. We have the option to pay cash, issue shares of common stock or any combination thereof for the aggregate amount due upon conversion. It is our intent to settle the principal amount of the 2032 Notes in cash upon any conversion. As a result, only the amounts payable in excess of the principal amounts upon conversion of the 2032 Notes are considered in diluted earnings per share under the treasury stock method. Cash Redemption at Our Option : We may redeem for cash the 2032C Notes on or after May 1, 2016 and the 2032D Notes on or after May 1, 2017 if the volume weighted average price of our common stock has been at least 130% of the conversion price for at least 20 trading days during any 30 consecutive trading day period. The redemption price will equal the principal amount plus accrued and unpaid interest. If we redeem the 2032C Notes prior to May 4, 2019, or the 2032D Notes prior to May 4, 2021, we will also pay a make-whole premium in cash equal to the present value of all remaining scheduled payments of interest from the redemption date to May 4, 2019 for the 2032C Notes, or to May 4, 2021 for the 2032D Notes, using a discount rate equal to 1.5% . Cash Repurchase at the Option of the Holder : We may be required by the holders of the 2032 Notes to repurchase for cash all or a portion of the 2032C Notes on May 1, 2019 and all or a portion of the 2032D Notes on May 1, 2021 at a price equal to the principal amount plus accrued and unpaid interest. Upon a change in control or a termination of trading, as defined in the indenture, holders of the 2032 Notes may require us to repurchase for cash all or a portion of their 2032 Notes at a price equal to the principal amount plus accrued and unpaid interest. 2033E and 2033F Notes: On February 12, 2013, we issued $300 million of the 2033E Notes and $300 million of the 2033F Notes. The initial conversion rate for the 2033 Notes is 91.4808 shares of common stock per $1,000 principal amount, equivalent to an initial conversion price of approximately $10.93 per share of common stock. Interest is payable in February and August of each year. During 2015, holders converted $7 million of aggregate principal amounts of the 2033E Notes, and we elected to settle the amounts due upon conversion entirely in cash. During 2015, we repurchased $60 million of aggregate principal amounts of the 2033E Notes and $3 million of aggregate principal amounts of the 2033F Notes, for cash. Conversion Rights : Holders may convert their 2033 Notes under the following circumstances: (1) if the 2033 Notes are called for redemption; (2) during any calendar quarter if the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the conversion price of the 2033 Notes (approximately $14.21 per share); (3) if the trading price of the 2033 Notes is less than 98% of the product of the closing price of our common stock and the conversion rate of the 2033 Notes during the periods specified in the indenture; (4) if specified distributions or corporate events occur, as set forth in the indenture for the 2033 Notes; or (5) at any time after November 15, 2032. Upon conversion, we will pay cash equal to the lesser of the aggregate principal amount and the conversion value of the notes being converted and cash, shares of common stock or a combination of cash and shares of common stock, at our option, for any remaining conversion obligation. As a result, only the amounts payable in excess of the principal amounts upon conversion of the 2033 Notes are considered in diluted earnings per share under the treasury stock method. Cash Redemption at Our Option : We may redeem for cash the 2033E Notes on or after February 20, 2018 and the 2033F Notes on or after February 20, 2020 at a price equal the principal amount plus accrued and unpaid interest. Cash Repurchase at the Option of the Holder : We may be required by the holders of the 2033 Notes to repurchase for cash all or a portion of the 2033E Notes on February 15, 2018 and on February 15, 2023 and all or a portion of the 2033F Notes on February 15, 2020 and on February 15, 2023 at a price equal to the principal amount plus accrued and unpaid interest. Upon a change in control or a termination of trading, as defined in the indenture, holders of the 2033 Notes may require us to repurchase for cash all or a portion of their 2033 Notes at a price equal to the principal amount plus accrued and unpaid interest. 2043G Notes: On November 12, 2013, we issued $1.03 billion principal amount of the 2043G Notes in exchange for $440 million in aggregate principal amount of our 2027 Notes, 2031A Notes, and 2031B Notes. Each $1,000 of principal amount at maturity had an original issue price of $800 . An amount equal to the difference between the original issue price and the principal amount at maturity will accrete in accordance with a schedule set forth in the indenture. The original principal amount of $820 million accretes up to $1.03 billion at maturity in 2043. The initial conversion rate for the 2043G Notes is 34.2936 shares of common stock per $1,000 principal amount at maturity, equivalent to an initial conversion price of approximately $29.16 per share of common stock. Interest is payable in May and November of each year. Conversion Rights : Holders may convert their 2043G Notes under the following circumstances: (1) if the 2043G Notes are called for redemption; (2) during any calendar quarter if the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the conversion price of the 2043G Notes (approximately $37.91 per share); (3) if the trading price of the 2043G Notes is less than 98% of the product of the closing price of our common stock and the conversion rate of the 2043G Notes during the periods specified in the indenture; (4) if specified distributions or corporate events occur, as set forth in the indenture; or (5) at any time after August 15, 2043. We have the option to pay cash, issue shares of common stock or any combination thereof, for the aggregate amount due upon conversion. It is our current intent to settle in cash the principal amount of the 2043G Notes upon conversion. As a result, the dilutive effect of the 2043G Notes in earnings per share is computed under the treasury stock method. Cash Redemption at Our Option : Prior to November 20, 2018, we may redeem for cash the 2043G Notes if the volume weighted average price of our common stock has been at least 130% of the conversion price for at least 20 trading days during any 30 consecutive trading day period. The redemption price will equal the principal amount at maturity plus accrued and unpaid interest. On or after November 20, 2018, we may redeem for cash the 2043G Notes without regard to the closing price of our common stock at a price equal the accreted principal amount plus accrued and unpaid interest. If we redeem the 2043G Notes prior to November 20, 2018, we are required to pay in cash a make-whole premium as specified in the indenture. Cash Repurchase at the Option of the Holder : Holders of the 2043G Notes may require us to repurchase for cash all or a portion of the 2043G Notes on November 15, 2028 at a price equal to the accreted principal amount of $917 million plus accrued and unpaid interest. Holders of the 2043G Notes may also require us to repurchase for cash all or a portion of their 2043G Notes at a price equal to the accreted principal amount plus accrued and unpaid interest upon a change in control or a termination of trading, as defined in the indenture. Other Facilities Revolving Credit Facilities: On February 12, 2015, we terminated our unused $255 million senior three -year revolving credit facility and entered into a senior five -year revolving credit facility. Under this credit facility, we can draw up to the lesser of $750 million or 80% of the net outstanding balance of certain trade receivables, as defined in the facility agreement. Any amounts drawn are collateralized by a security interest in such trade receivables. The credit facility contains customary covenants and conditions, including as a funding condition the absence of any event or circumstance that has a material adverse effect on certain of our operations, assets, prospects, business, or condition, and including negative covenants that limit or restrict our ability to create liens on, or dispose of, the collateral underlying the obligations under this facility. Interest is payable on any outstanding principal balance at a variable rate equal to the London Interbank Offered Rate

Loss Contingency [Abstract]
Contingencies	Contingencies We have accrued a liability and charged operations for the estimated costs of adjudication or settlement of various asserted and unasserted claims existing as of the applicable balance sheet dates, including those described below. We are currently a party to other legal actions arising from the normal course of business, none of which is expected to have a material adverse effect on our business, results of operations, or financial condition. Patent Matters As is typical in the semiconductor and other high technology industries, from time to time others have asserted, and may in the future assert, that our products or manufacturing processes infringe their intellectual property rights. On November 21, 2014, Elm 3DS Innovations, LLC ("Elm") filed a patent infringement action against Micron, Micron Semiconductor Products, Inc., and Micron Consumer Products Group, Inc. in the U.S. District Court for the District of Delaware. On March 27, 2015, Elm filed an amended complaint against the same entities. The amended complaint alleges that unspecified semiconductor products of ours that incorporate multiple stacked die infringe thirteen U.S. patents and seeks damages, attorneys’ fees, and costs. On December 15, 2014, Innovative Memory Solutions, Inc. filed a patent infringement action against us in the U.S. District Court for the District of Delaware. The complaint alleges that a variety of our NAND Flash products infringe eight U.S. patents and seeks damages, attorneys' fees, and costs. Among other things, the above lawsuits pertain to certain of our DDR DRAM, DDR2 DRAM, DDR3 DRAM, DDR4 DRAM, SDR SDRAM, PSRAM, RLDRAM, LPDRAM, NAND Flash, and certain other memory products we manufacture, which account for a significant portion of our net sales. We are unable to predict the outcome of assertions of infringement made against us and therefore cannot estimate the range of possible loss. A determination that our products or manufacturing processes infringe the intellectual property rights of others or entering into a license agreement covering such intellectual property could result in significant liability and/or require us to make material changes to our products and/or manufacturing processes. Any of the foregoing could have a material adverse effect on our business, results of operations, or financial condition. Qimonda On January 20, 2011, Dr. Michael Jaffé, administrator for Qimonda insolvency proceedings, filed suit against Micron and Micron Semiconductor B.V., our Netherlands subsidiary ("Micron B.V."), in the District Court of Munich, Civil Chamber. The complaint seeks to void under Section 133 of the German Insolvency Act a share purchase agreement between Micron B.V. and Qimonda signed in fall 2008 pursuant to which Micron B.V. purchased substantially all of Qimonda's shares of Inotera Memories, Inc. (the "Inotera Shares"), representing approximately 55% of our total shares in Inotera as of September 3, 2015, and seeks an order requiring us to re-transfer those shares to the Qimonda estate. The complaint also seeks, among other things, to recover damages for the alleged value of the joint venture relationship with Inotera and to terminate under Sections 103 or 133 of the German Insolvency Code a patent cross-license between us and Qimonda entered into at the same time as the share purchase agreement. Following a series of hearings with pleadings, arguments and witnesses on behalf of the Qimonda estate, on March 13, 2014, the Court issued judgments: (1) ordering Micron B.V. to pay approximately $1 million in respect of certain Inotera shares sold in connection with the original share purchase; (2) ordering Micron B.V. to disclose certain information with respect to any Inotera Shares sold by it to third parties; (3) ordering Micron B.V. to disclose the benefits derived by it from ownership of the Inotera Shares, including in particular, any profits distributed on such shares and all other benefits; (4) denying Qimonda’s claims against Micron for any damages relating to the joint venture relationship with Inotera; and (5) determining that Qimonda's obligations under the patent cross-license agreement are canceled. In addition, the Court issued interlocutory judgments ordering, among other things: (1) that Micron B.V. transfer to the Qimonda estate the Inotera Shares still owned by it and pay to the Qimonda estate compensation in an amount to be specified for any Inotera Shares sold to third parties; and (2) that Micron B.V. pay the Qimonda estate as compensation an amount to be specified for benefits derived by it from ownership of the Inotera Shares. The interlocutory judgments have no immediate, enforceable effect on us, and, accordingly, we expect to be able to continue to operate with full control of the Inotera Shares subject to further developments in the case. We have filed a notice of appeal, and the parties have submitted briefs to the appeals court. The next hearing on the matter has not yet been scheduled. We are unable to predict the outcome of the matter and therefore cannot estimate the range of possible loss. The final resolution of this lawsuit could result in the loss of the Inotera Shares or monetary damages, unspecified damages based on the benefits derived by Micron B.V. from the ownership of the Inotera Shares, and/or the termination of the patent cross-license, which could have a material adverse effect on our business, results of operation, or financial condition. As of September 3, 2015, the Inotera Shares had a carrying value in equity method investments for purposes of our financial reporting of $683 million and a market value of $846 million. Other In the normal course of business, we are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party. It is not possible to predict the maximum potential amount of future payments under these types of agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, our payments under these types of agreements have not had a material adverse effect on our business, results of operations, or financial condition.

Redeemable Convertible Notes [Abstract]
Redeemable Convertible Notes [Text Block]	Redeemable Convertible Notes Under the terms of the indentures governing the 2033 Notes, upon conversion, we would be required to pay cash equal to the lesser amount of (1) the aggregate principal amount or (2) the conversion value of the notes being converted. To the extent the conversion value exceeds the principal amount, we could pay cash, shares of common stock, or a combination thereof, at our option, for the amount of such excess. The 2033 Notes were convertible at the option of the holders as of September 3, 2015 and August 28, 2014 . Therefore, the 2033 Notes were classified as current debt and the aggregate difference between the principal amount and the carrying value of $49 million as of September 3, 2015 and $68 million as of August 28, 2014 was classified as redeemable convertible notes in the accompanying consolidated balance sheets.

Equity [Abstract]
Equity	Equity Micron Shareholders' Equity Common Stock Repurchases: Since the first quarter of 2015, our Board of Directors has authorized the repurchase of up to $1.25 billion of our outstanding common stock, $250 million of which was authorized in the first quarter of 2016. Any repurchases under the authorization may be made in open market purchases, block trades, privately-negotiated transactions, and/or derivative transactions. Repurchases are subject to market conditions and our ongoing determination of the best use of available cash. During 2015, we repurchased 42 million shares for $831 million (including commissions) through open market transactions, which were recorded as treasury stock. Capped Calls Issued and Outstanding Capped Calls : We have entered into capped calls, which are intended to reduce the effect of potential dilution from our convertible notes. The capped calls provide for our receipt of cash or shares, at our election, from our counterparties if the trading price of our stock is above a specified initial strike price at the expiration dates. The amounts receivable varies based on the trading price of our stock, up to specified cap prices. The dollar value of the cash or shares that we would receive from the capped calls upon their expiration date ranges from $0 if the trading price of our stock is below the initial strike price for all of the capped calls to $814 million if the trading price of our stock is at or above the cap price for all of the capped calls. We paid $57 million in 2011 to purchase the 2031 Capped Calls, $103 million in 2012 to purchase the 2032 Capped Calls and $48 million in 2013 to purchase the 2033 Capped Calls. The amounts paid were recorded as charges to additional capital. The following table presents information related to the issued and outstanding capped calls as of September 3, 2015 : Capped Calls Strike Price Cap Price Range Underlying Common Shares Value at Expiration (1) Expiration Dates Low High Minimum Maximum 2031 Jan 2016 – Feb 2016 $ 9.50 $ 13.17 $ 13.17 18 $ — $ 67 2032C May 2016 – Nov 2017 9.80 14.26 15.69 56 — 307 2032D Nov 2016 – May 2018 10.16 14.62 16.04 44 — 244 2033E Jan 2018 – Feb 2018 10.93 14.51 14.51 27 — 98 2033F Jan 2020 – Feb 2020 10.93 14.51 14.51 27 — 98 172 $ — $ 814 (1) Settlement in cash on the respective expiration dates would result in us receiving an amount ranging from zero, if the market price per share of our common stock is at or below the low strike price, to the maximum amount if the market price per share of our common stock is at or above the high cap price. If share settlement were elected, the number of shares received would be determined by the value of the capped calls at the time of settlement divided by the share price on the settlement date. Settlement of the capped calls prior to the expiration dates may be for an amount less than the maximum value at expiration. Expiration and Unwind of Capped Calls : A portion of our 2031 Capped Calls expired in the fourth quarter of 2015. We elected share settlement and received 3 million shares of our stock, equivalent to approximately $50 million based on the trading stock price at the time of expiration, which were recorded as treasury stock. In May 2014, we and the counterparties agreed to terminate and unwind a portion of our 2031 Capped Calls. We elected share settlement and received 3 million shares of our stock, equivalent to approximately $86 million based on the trading stock price at the time of the unwind. The shares received in May 2014 were retired from treasury stock in 2014. Accumulated Other Comprehensive Income (Loss): Changes in accumulated other comprehensive income (loss) by component for the year ended September 3, 2015 , were as follows: Cumulative Foreign Currency Translation Adjustments Gains (Losses) on Derivative Instruments, Net Gains (Losses) on Investments, Net Pension Liability Adjustments Total Balance as of August 28, 2014 $ 42 $ 12 $ 1 $ 1 $ 56 Other comprehensive income (loss) before reclassifications (42 ) (11 ) (2 ) 33 (22 ) Amount reclassified out of accumulated other comprehensive income — (6 ) (2 ) (2 ) (10 ) Tax effects — — — (11 ) (11 ) Other comprehensive income (loss) (42 ) (17 ) (4 ) 20 (43 ) Balance as of September 3, 2015 $ — $ (5 ) $ (3 ) $ 21 $ 13 Noncontrolling Interests in Subsidiaries As of 2015 2014 Noncontrolling Interest Balance Noncontrolling Interest Percentage Noncontrolling Interest Balance Noncontrolling Interest Percentage IMFT (1) $ 829 49 % $ 693 49 % MP Mask (1) 93 50 % 93 50 % Other 15 Various 16 Various $ 937 $ 802 (1) Entity is a variable interest entity. IMFT: Since inception in 2006, we have owned 51% of IMFT, a joint venture between us and Intel to manufacture NAND Flash and 3D XPoint memory products for the exclusive use of the members. IMFT is governed by a Board of Managers, for which the number of managers appointed by each member varies based on the members' respective ownership interests. The IMFT joint venture agreement extends through 2024 and includes certain buy-sell rights. Commencing in January 2015, Intel can put to us, and commencing in January 2018, we can call from Intel, Intel's interest in IMFT, in either case, for an amount equal to the noncontrolling interest balance attributable to Intel at that time. If Intel elects to sell to us, we can elect to set the closing date of the transaction to be any time within two years following such election by Intel and can elect to receive financing of the purchase price from Intel for one to two years from the closing date. IMFT manufactures memory products using designs and technology we develop with Intel. We generally share with Intel the costs of product design and process development activities for NAND Flash memory and 3D XPoint memory. Our R&D expenses were reduced by reimbursements from Intel of $224 million , $137 million , and $127 million for 2015 , 2014 , and 2013 , respectively. We sell a portion of our products to Intel through our IMFT joint venture at long-term negotiated prices approximating cost. Sales of products to Intel under this arrangement were $420 million , $423 million , and $387 million for 2015 , 2014 , and 2013 , respectively. Receivables from Intel as of September 3, 2015 and August 28, 2014 , were $67 million and $66 million , respectively, for these sales. The following table presents the assets and liabilities of IMFT included in our consolidated balance sheets: As of 2015 2014 Assets Cash and equivalents $ 134 $ 84 Receivables 79 73 Inventories 65 48 Other current assets 7 5 Total current assets 285 210 Property, plant and equipment, net 1,768 1,545 Other noncurrent assets 49 47 Total assets $ 2,102 $ 1,802 Liabilities Accounts payable and accrued expenses $ 182 $ 106 Deferred income 9 8 Current debt 22 21 Total current liabilities 213 135 Long-term debt 49 71 Other noncurrent liabilities 100 110 Total liabilities $ 362 $ 316 Amounts exclude intercompany balances that were eliminated in our consolidated balance sheets. Creditors of IMFT have recourse only to IMFT's assets and do not have recourse to any other of our assets. The following table presents IMFT's distributions to and contributions from its shareholders: For the year ended 2015 2014 2013 IMFT distributions to Micron $ 6 $ 10 $ 38 IMFT distributions to Intel 6 10 37 Micron contributions to IMFT 148 106 12 Intel contributions to IMFT 142 102 11 MP Mask: In 2006, we formed a joint venture with Photronics to produce photomasks for leading-edge and advanced next generation semiconductors. On March 24, 2015, we notified Photronics of our election to terminate MP Mask effective in May 2016. Upon termination, we have the right to acquire Photronics' interest in MP Mask for an amount equal to the noncontrolling interest balance. Since its inception, we and Photronics have each owned approximately 50% of MP Mask. We purchase a substantial majority of the photomasks produced by MP Mask pursuant to a supply arrangement. The assets and liabilities of MP Mask included in our consolidated balance sheets were as follows: As of 2015 2014 Current assets $ 21 $ 24 Noncurrent assets (primarily property, plant and equipment) 180 203 Current liabilities 21 28 Noncurrent liabilities — 14 Amounts exclude intercompany balances that were eliminated in our consolidated balance sheets. Creditors of MP Mask have recourse only to MP Mask's assets and do not have recourse to any other of our assets. MMT: As of August 29, 2013, noncontrolling interests in MMT were 11% . In 2014, we purchased additional interests in MMT for an aggregate of $146 million , and as of August 28, 2014, noncontrolling interests in MMT were less than 1%. Substantially all of the MMT shares purchased in 2014 were financed with a short-term loan from a seller. As a result of the purchases of MMT shares in 2014, in aggregate, noncontrolling interests decreased by $180 million and additional capital increased by $34 million . Restrictions on Net Assets As a result of the reorganization proceedings of the MMJ Companies initiated on March 23, 2012, and for so long as such proceedings continue, the MMJ Group is subject to certain restrictions on dividends, loans, and advances. In addition, our ability to access IMFT's cash and other assets through dividends, loans, or advances, including to finance our other operations, is subject to agreement by Intel. As a result, our total restricted net assets (net assets less intercompany balances and noncontrolling interests) as of September 3, 2015 were $3.35 billion for the MMJ Group and $911 million for IMFT, which included cash and equivalents of $748 million for the MMJ Group and $134 million for IMFT. (See "Micron Memory Japan, Inc." note and "IMFT" above.) As of September 3, 2015 , our retained earnings included undistributed earnings from our equity method investees of $232 million .

Derivative Instrument Detail [Abstract]
Derivative Financial Instruments	Derivative Instruments We use derivative instruments to manage a portion of our exposure to changes in currency exchange rates from our monetary assets and liabilities denominated in currencies other than the U.S. dollar. We have also had convertible note settlement obligations which were accounted for as derivative instruments as a result of our elections to settle conversions in cash. We do not use derivative instruments for speculative purpose. Derivative Instruments without Hedge Accounting Designation Currency Derivatives: We use derivative instruments to manage a portion of our exposure to changes in currency exchange rates from our monetary assets and liabilities. Our primary objective for entering into currency derivatives is to reduce the volatility that changes in currency exchange rates have on our earnings. To hedge our exposures to monetary assets and liabilities, we generally utilize a rolling hedge strategy with currency forward contracts that mature within 35 days. At the end of each reporting period, monetary assets and liabilities denominated in currencies other than the U.S. dollar are remeasured in U.S. dollars and the associated outstanding forward contracts are marked-to-market. Currency forward contracts are valued at fair values based on the middle of bid and ask prices of dealers or exchange quotations (Level 2 fair value measurements). In connection with the currency exchange rate risk associated with the MMJ Acquisition in July 2013, we entered into currency exchange transactions (the "MMJ Acquisition Hedges"). The MMJ Acquisition Hedges were not designated for hedge accounting and were remeasured at fair value each period. We recorded losses from the MMJ Acquisition Hedges of $228 million in 2013. To mitigate the risk of the yen strengthening against the U.S. dollar on the MMJ creditor installment payments due in December 2014 and December 2015, we entered into forward contracts to purchase 20 billion yen on November 28, 2014 and 10 billion yen on November 27, 2015. In the first quarter of 2015, we paid $33 million to settle the 20 billion yen forward contracts. Realized and unrealized gains and losses on currency derivatives without hedge accounting designation as well as the change in the underlying monetary assets and liabilities due to changes in currency exchange rates are included in other non-operating income (expense), net. Convertible Notes Settlement Obligations: During 2015, holders elected to convert a portion of our 2033E Notes. In 2014, holders elected to convert substantially all of our remaining 2014 Notes, 2027 Notes, 2031A Notes, and 2031B Notes. As a result of our elections to settle the amounts due upon conversion in cash, each of the settlement obligations became derivative debt liabilities subject to mark-to-market accounting treatment for a period of approximately 30 days, beginning on the dates we notified the holder of our intention to settle the obligation in cash through the settlement dates. The fair values of the underlying derivative settlement obligations were initially determined using the Black-Scholes option valuation model (Level 2 fair value measurements). The Black-Scholes model requires the input of assumptions, including the stock price, expected stock-price volatility, estimated option life, risk-free interest rate, and dividend rate. The subsequent measurements and final settlement amounts of our convertible note settlement obligations were based on the volume-weighted average stock price (Level 2 fair value measurements). Changes in fair values of the derivative settlement obligations were included in other non-operating income (expense), net. Total notional amounts and gross fair values for derivative instruments without hedge accounting designation were as follows: Notional Amount (1) Fair Value of Current Assets (2) Current Liabilities (3) Noncurrent Liabilities (4) As of September 3, 2015 Currency forward contracts: Yen $ 928 $ — $ (24 ) $ — Singapore dollar 282 — — — New Taiwan dollar 89 — — — Yuan 32 1 — — Euro 29 — — — Shekel 27 — — — British Pound 19 — — — $ 1,406 $ 1 $ (24 ) $ — As of August 28, 2014 Currency forward contracts: Yen $ 554 $ — $ (12 ) $ (6 ) Singapore dollar 330 — — — Euro 245 — (1 ) — Shekel 62 — (1 ) — $ 1,191 Convertible notes settlement obligations 12 — (389 ) — $ — $ (403 ) $ (6 ) (1) Notional amounts of forward contracts in U.S. dollars and convertible notes settlement obligations in shares. (2) Included in receivables – other. (3) Included in accounts payable and accrued expenses – other for forward contracts and in current debt for convertible notes settlement obligations. (4) Included in other noncurrent liabilities. Net gains (losses) for derivative instruments without hedge accounting designation were included in other non-operating income (expense), net as follows: For the year ended 2015 2014 2013 Foreign exchange contracts $ (64 ) $ (27 ) $ (222 ) Convertible notes settlement obligations 7 (59 ) — Derivative Instruments with Cash Flow Hedge Accounting Designation Currency Derivatives: We utilize currency forward contracts that generally mature within 12 months to hedge our exposure to changes in cash flows from changes in currency exchange rates for certain capital expenditures. Currency forward contracts are measured at fair value based on market-based observable inputs including currency exchange spot and forward rates, interest rate, and credit risk spread (Level 2 fair value measurements). For derivative instruments designated as cash flow hedges, the effective portion of the realized and unrealized gain or loss on the derivatives is included as a component of accumulated other comprehensive income (loss). Amounts in accumulated other comprehensive income (loss) are reclassified into earnings in the same line items of the consolidated statements of operations and in the same periods in which the underlying transactions affect earnings. The ineffective or excluded portion of the realized and unrealized gain or loss is included in other non-operating income (expense), net. Total notional amounts and gross fair values for derivative instruments with cash flow hedge accounting designation were as follows: Notional Amount (in U.S. Dollars) Fair Value of Current Assets (1) Current Liabilities (2) As of September 3, 2015 Yen $ 81 $ 3 $ — Euro 12 — — $ 93 $ 3 $ — As of August 28, 2014 Yen $ 94 $ — $ (2 ) Euro 24 — — $ 118 $ — $ (2 ) (1) Included in receivables – other. (2) Included in accounts payable and accrued expenses – other. For 2015 , 2014 , and 2013, we recognized losses of $10 million , $4 million , and $8 million , respectively, in accumulated other comprehensive income (loss) from the effective portion of cash flow hedges. The ineffective and excluded portions of cash flow hedges recognized in other non-operating income (expense) were not significant in 2015, 2014, or 2013. For 2015 , 2014 , and 2013, we reclassified gains of $6 million , $4 million , and $1 million , respectively, from accumulated other comprehensive income (loss) to earnings. As of September 3, 2015 , $3 million of net gains from cash flow hedges included in accumulated other comprehensive income (loss) is expected to be reclassified into earnings in the next 12 months. Derivative Counterparty Credit Risk and Master Netting Arrangements Our derivative instruments expose us to credit risk to the extent counterparties may be unable to meet the terms of the contracts. Our maximum exposure to loss due to credit risk if counterparties fail completely to perform according to the terms of the contracts would generally equal the fair value of assets for these contracts as listed in the tables above. We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading risk across multiple financial institutions. We enter into master netting arrangements with our counterparties to mitigate credit risk in derivative hedge transactions. These master netting arrangements allow us and our counterparties to net settle amounts owed to each other. Derivative assets and liabilities that can be net settled with each counterparty under these arrangements have been presented in our consolidated balance sheets on a net basis. As of September 3, 2015 and August 28, 2014 , amounts netted were not significant.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Accounting standards establish three levels of inputs that may be used to measure fair value: quoted prices in active markets for identical assets or liabilities (referred to as Level 1), inputs other than Level 1 that are observable for the asset or liability either directly or indirectly (referred to as Level 2), and unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities (referred to as Level 3). All of our marketable debt and equity investments (excluding equity method investments) were classified as available-for-sale and carried at fair value. In addition to the fair value measurements disclosed in the "Cash and Investments" note, as of September 3, 2015 and August 28, 2014 , we had certificates of deposit classified as restricted cash (included in other noncurrent assets) of $45 million and $27 million , respectively, valued using Level 2 fair value measurements. In connection with our repurchases of debt in 2015, 2014, and 2013, we determined the fair value of the debt components of our convertible notes as if they were stand-alone instruments, using interest rates for similar nonconvertible debt issued by entities with credit ratings comparable to ours (Level 2). Amounts reported as cash and equivalents, receivables, and accounts payable and accrued expenses approximate fair value. The estimated fair value and carrying value of debt instruments (carrying value excludes the equity and mezzanine equity components of our convertible notes) were as follows: As of 2015 2014 Fair Value Carrying Value Fair Value Carrying Value Notes and MMJ creditor installment payments $ 5,020 $ 5,077 $ 3,634 $ 3,483 Convertible notes 2,508 1,472 5,886 2,117 The fair values of our convertible notes were determined based on inputs that were observable in the market or that could be derived from, or corroborated with, observable market data, including the trading price of our convertible notes when available, our stock price, and interest rates based on similar debt issued by parties with credit ratings similar to ours (Level 2). The fair value of our other debt instruments was estimated based on discounted cash flows using inputs that were observable in the market or that could be derived from, or corroborated with, observable market data, including the trading price of our notes, when available, and interest rates based on similar debt issued by parties with credit ratings similar to ours (Level 2). In connection with our restructure and asset impairment charges in 2014 and 2013, the fair value of our 200 mm wafer fabrication equipment in Kiryat Gat, Israel was determined primarily based on the expected proceeds from the sale and the fair value of a supply agreement to manufacture NOR flash memory at the facility (Level 3). The fair values of our MIT assets and our Light-emitting Diode ("LED") production assets were based on quotations obtained from equipment dealers, which consider the remaining useful life and configuration of the equipment (Level 3).

Equity Plans	Equity Plans As of September 3, 2015 , our equity plans permit us to issue an aggregate of up to 170 million shares of common stock, of which 112 million shares were available for future awards. Awards are subject to terms and conditions as determined by our Board of Directors. Stock Options Our stock options are generally exercisable in increments of either one-fourth or one-third per year beginning one year from the date of grant. Stock options issued after February 2014 generally expire eight years from the date of grant. Options issued prior to February 2014 generally expire six years from the date of grant. Option activity for 2015 is summarized as follows: Number of Shares Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Life (In Years) Aggregate Intrinsic Value Outstanding at August 28, 2014 48 $ 10.57 Granted 8 34.45 Exercised (10 ) 7.35 Canceled or expired (2 ) 15.93 Outstanding at September 3, 2015 44 15.33 3.8 $ 256 Exercisable at September 3, 2015 18 $ 9.33 2.4 $ 145 Expected to vest after September 3, 2015 25 19.11 4.7 109 The total intrinsic value was $229 million , $421 million , and $103 million for options exercised during 2015 , 2014 , and 2013 , respectively. Stock options granted and assumptions used in the Black-Scholes option valuation model were as follows: For the year ended 2015 2014 2013 Stock options granted 8 12 18 Weighted-average grant-date fair value per share $ 14.79 $ 9.64 $ 3.34 Average expected life in years 5.6 4.9 5.1 Weighted-average expected volatility 45 % 48 % 59 % Weighted-average risk-free interest rate 1.7 % 1.6 % 0.7 % The expected volatilities utilized were based on implied volatilities from traded options on our stock and on our historical volatility. The expected lives of options granted were based, in part, on historical experience and on the terms and conditions of the options. The risk-free interest rates utilized were based on the U.S. Treasury yield in effect at each grant date. No dividends were assumed in estimated option values. Restricted Stock and Restricted Stock Units ("Restricted Stock Awards") As of September 3, 2015 , there were 14 million shares of Restricted Stock Awards outstanding, of which 1 million were performance-based or market-based Restricted Stock Awards. For service-based Restricted Stock Awards, restrictions generally lapse in one-fourth increments during each year of employment after the grant date. Vesting for performance-based awards is contingent upon meeting a specified return on assets ("ROA"), as defined, over a three -year performance period and vesting for market-based Restricted Stock Awards is contingent upon achieving total shareholder return ("TSR") relative to the companies included in the S&P 500 over a three -year performance period. At the end of the performance period, the number of actual shares to be awarded varies between 0% and 200% of target amounts, depending upon the achievement level of the specified ROA or TSR. Restricted Stock Awards activity for 2015 is summarized as follows: Number of Shares Weighted-Average Grant Date Fair Value Per Share Outstanding at August 28, 2014 13 $ 15.08 Granted 7 32.60 Restrictions lapsed (5 ) 13.48 Canceled (1 ) 19.81 Outstanding at September 3, 2015 14 23.88 Expected to vest after September 3, 2015 13 $ 23.78 For the year ended 2015 2014 2013 Restricted stock awards granted 7 7 7 Weighted-average grant-date fair values per share $ 32.60 $ 21.88 $ 6.23 Aggregate fair values at vesting date 155 115 17 Stock-based Compensation Expense For the year ended 2015 2014 2013 Stock-based compensation expense by caption: Cost of goods sold $ 65 $ 39 $ 27 Selling, general and administrative 60 50 45 Research and development 42 25 18 Other 1 1 1 $ 168 $ 115 $ 91 Stock-based compensation expense by type of award: Stock options $ 81 $ 61 $ 57 Restricted stock awards 87 54 34 $ 168 $ 115 $ 91 Stock-based compensation expense of $9 million and $9 million was capitalized and remained in inventory as of September 3, 2015 and August 28, 2014 , respectively. As of September 3, 2015 , $384 million of total unrecognized compensation costs for unvested awards, net of estimated forfeitures, was expected to be recognized through the fourth quarter of 2019 , resulting in a weighted-average period of 1.3 years. Stock-based compensation expense in the above presentation does not reflect any significant income tax benefits, which is consistent with our treatment of income or loss from our U.S. operations.

Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits Disclosure	Employee Benefit Plans We have employee retirement plans at our U.S. and international sites. Details of the more significant plans are discussed as follows: Employee Savings Plan for U.S. Employees We have 401(k) retirement plans under which U.S. employees may contribute up to 75% of their eligible pay (subject to IRS annual contribution limits) to various savings alternatives, none of which include direct investment in our stock. We match in cash eligible contributions from employees up to 5% of the employee's annual eligible earnings. Contribution expense for the 401(k) plans was $55 million , $44 million , and $41 million in 2015 , 2014 , and 2013 , respectively. Retirement Plans We have pension plans in various countries. The pension plans are only available to local employees and are generally government mandated. As of September 3, 2015 , the projected benefit obligations of our plans was $132 million and plan assets were $105 million . As of August 28, 2014 , the projected benefit obligations of our plans was $164 million and plan assets were $90 million . Pension expense was not significant for 2015 , 2014 , or 2013 .

For 2014, our MBU and EBU operating segments recorded restructure and asset impairment charges of $21 million and $20 million , respectively. For 2013, restructure and asset impairment charges of $20 million , $14 million , $12 million , and $12 million were recognized by our SBU, EBU, MBU, and CNBU operating segments, respectively. The remaining restructure and asset impairment charges were recognized by our other segments that do not meet the thresholds of a reportable segment. As of September 3, 2015 , we do not anticipate incurring any significant additional costs for these restructure activities. For 2014 and 2013, other restructure included charges associated with workforce optimization activities and with our efforts to wind down our 200 mm operations primarily in Agrate, Italy and Kiryat Gat, Israel. For 2013, we also recognized charges of $33 million primarily to impair certain production assets used in the development of LED technology, $62 million to impair the assets of MIT, a wholly-owned subsidiary, to their estimated fair values in connection with the sale of MIT to LFoundry, and $26 million in connection with the restructure of a consortium agreement with ST, whereby certain assets and approximately 500 employees from our Agrate, Italy fabrication facility were transferred to ST. For 2013, we also recognized a gain of $25 million related to the termination of a lease with Transform Solar Pty Ltd. ("Transform"), an equity method investee, to a portion of our manufacturing facilities in Boise, Idaho.

We also entered into a seven -year term patent cross-license agreement with Rambus, Inc. that allows us to avoid costs of patent-related litigation during the term. The primary benefits we received from these arrangements were (1) the settlement and termination of all existing litigation, (2) the avoidance of future litigation expenses and (3) the avoidance of future management and customer disruptions. As a result, other operating expense for 2014 included a $233 million charge to accrue a liability, which reflects the discounted value of amounts due under this arrangement.

We operate in a number of locations outside the U.S., including Singapore and, to a lesser extent, Taiwan, where we have tax incentive agreements that are, in part, conditional upon meeting certain business operations and employment thresholds. The effect of tax incentive arrangements, which expire in whole or in part at various dates through 2030, reduced our tax provision for 2015 , 2014 , and 2013 by $338 million (benefitting our diluted earnings per share by $0.29 ), $286 million ( $0.24 per diluted share), and $141 million ( $0.13 per diluted share), respectively. Deferred income taxes reflect the net tax effects of temporary differences between the bases of assets and liabilities for financial reporting and income tax purposes as well as carryforwards. Deferred tax assets and liabilities consist of the following: As of 2015 2014 Deferred tax assets: Net operating loss and tax credit carryforwards $ 2,869 $ 3,162 Accrued salaries, wages and benefits 143 152 Other accrued liabilities 97 113 Property, plant and equipment — 284 Other 86 104 Gross deferred tax assets 3,195 3,815 Less valuation allowance (2,051 ) (2,443 ) Deferred tax assets, net of valuation allowance 1,144 1,372 Deferred tax liabilities: Debt discount (207 ) (291 ) Unremitted earnings on certain subsidiaries (162 ) (115 ) Product and process technology (43 ) (29 ) Other (57 ) (67 ) Deferred tax liabilities (469 ) (502 ) Net deferred tax assets $ 675 $ 870 Reported as: Current deferred tax assets (included in other current assets) $ 104 $ 228 Noncurrent deferred tax assets 597 816 Current deferred tax liabilities (included in accounts payable and accrued expenses) (4 ) (4 ) Noncurrent deferred tax liabilities (included in other noncurrent liabilities) (22 ) (170 ) Net deferred tax assets $ 675 $ 870 As of September 3, 2015 , we had a valuation allowance of $1.16 billion against substantially all U.S. net deferred tax assets, primarily related to net operating loss carryforwards. The valuation allowance is based on our assessment of the deferred tax assets that are more likely than not to be realized. As of September 3, 2015 , we had partial valuation allowances of $710 million for Japan and $177 million for our other foreign subsidiaries against net deferred tax assets, primarily related to net operating loss carryforwards. As of September 3, 2015 , we had $3.81 billion of net operating loss carryforwards in Japan of which $2.19 billion is subject to a valuation allowance. Our valuation allowance decreased $392 million in 2015 primarily due to the utilization of U.S. and foreign net operating losses as well as adjustments based on management's assessment of the amount of foreign net operating losses that are more likely than not to be realized. We have a full valuation allowance for our net deferred tax asset associated with our U.S. operations. Management continues to evaluate future projected financial performance to determine whether such performance is sufficient evidence to support a reduction in or reversal of the valuation allowances. The amount of the deferred tax asset considered realizable could be adjusted if significant positive evidence increases. Income taxes on U.S. operations for 2015 and 2014 were substantially offset by changes in the valuation allowance. As of September 3, 2015 , our federal, state, and foreign net operating loss carryforward amounts and expiration periods as reported to tax authorities, were as follows: Year of Expiration U.S. Federal State Japan Other Foreign Total 2016 - 2020 $ — $ 103 $ 1,311 $ 1,011 $ 2,425 2021 - 2025 — 265 2,499 294 3,058 2026 - 2030 2,022 1,028 — — 3,050 2031 - 2035 1,999 652 — — 2,651 Indefinite — — — 30 30 $ 4,021 $ 2,048 $ 3,810 $ 1,335 $ 11,214 As of September 3, 2015 , our federal and state tax credit carryforward amounts and expiration periods as reported to tax authorities, were as follows: Year of Tax Credit Expiration Federal State Total 2016 - 2020 $ 20 $ 65 $ 85 2021 - 2025 99 43 142 2026 - 2030 65 61 126 2031 - 2035 119 — 119 Indefinite — 39 39 $ 303 $ 208 $ 511 We have not recognized deferred tax assets of $307 million for excess tax benefits that arose directly from tax deductions related to equity compensation greater than amounts recognized for financial reporting. These excess stock compensation benefits will be credited to additional capital if realized. We use the "with and without" method, as described in ASC 740, for purposes of determining when excess tax benefits have been realized. Provision has been made for deferred taxes on undistributed earnings of non-U.S. subsidiaries to the extent that dividend payments from such companies are expected to result in additional tax liabilities. Remaining undistributed earnings of $6.96 billion as of September 3, 2015 have been indefinitely reinvested; therefore, no provision has been made for taxes due on approximately $8.52 billion of the excess of the financial reporting amount over the tax basis of investments in foreign subsidiaries that are indefinitely reinvested. Generally, this amount becomes taxable upon a repatriation of assets from the subsidiary or a sale or liquidation of the subsidiary. Determination of the amount of unrecognized deferred tax liabilities related to investments in these foreign subsidiaries is not practicable. Below is a reconciliation of the beginning and ending amount of unrecognized tax benefits: For the year ended 2015 2014 2013 Beginning unrecognized tax benefits $ 228 $ 78 $ 77 Increases related to tax positions taken during current year 119 152 4 Increases related to tax positions from prior years 17 — — Foreign currency translation increases (decreases) to tax positions (6 ) 1 4 Lapse of statute of limitations (6 ) (1 ) — Settlements with tax authorities (1 ) (1 ) (8 ) Decreases related to tax positions from prior years — (1 ) — Unrecognized tax benefits acquired in current year — — 1 Ending unrecognized tax benefits $ 351 $ 228 $ 78 Included in the unrecognized tax benefits balance as of September 3, 2015 , August 28, 2014 , and August 29, 2013 were $53 million , $66 million , and $63 million , respectively, of unrecognized income tax benefits, which if recognized, would affect our effective tax rate. The increase in unrecognized tax benefits in 2015 primarily related to transfer pricing and other matters which were substantially offset by changes in our deferred tax asset valuation allowance. We recognize interest and penalties related to income tax matters within income tax expense. As of September 3, 2015 , August 28, 2014 , and August 29, 2013 , the amount accrued for interest and penalties related to uncertain tax positions was $16 million , $19 million , and $16 million , respectively. The resolution of tax audits or lapses of statute of limitations could also reduce our unrecognized tax benefits. Although the timing of final resolution is uncertain, the estimated potential reduction in our unrecognized tax benefits in the next 12 months ranges from $0 to $67 million , including interest and penalties. We and our subsidiaries file income tax returns with the U.S. federal government, various U.S. states and various foreign jurisdictions throughout the world. Our U.S. federal and state tax returns remain open to examination for 2011 through 2015. In addition, tax returns open to examination in multiple foreign taxing jurisdictions range from the years 2007 to 2015. We believe that adequate amounts of taxes and related interest and penalties have been provided for, and any adjustments as a result of examinations are not expected to materially adversely affect our business, results of operations or financial condition.

Segment Reporting [Abstract]
Segment Information	Segment Information Segment information reported herein is consistent with how it is reviewed and evaluated by our chief operating decision maker. We have the following four business units, which are our reportable segments: Compute and Networking Business Unit ("CNBU"): Includes memory products sold into compute, networking, graphics, and cloud server markets. Mobile Business Unit ("MBU"): Includes memory products sold into smartphone, tablet, and other mobile-device markets. Storage Business Unit ("SBU"): Includes memory products sold into enterprise, client, cloud, and removable storage markets. SBU also includes products sold to Intel through our IMFT joint venture. Embedded Business Unit ("EBU"): Includes memory products sold into automotive, industrial, connected home, and consumer electronics markets. Certain operating expenses directly associated with the activities of a specific segment are charged to that segment. Other indirect operating expenses (income) are generally allocated to segments based on their respective percentage of cost of goods sold or forecasted wafer production. The unallocated amount of operating expense for 2014 related to the Rambus settlement. We do not identify or report internally our assets or capital expenditures by segment, nor do we allocate gains and losses from equity method investments, interest, other non-operating income or expense items, or taxes to segments. There are no differences in the accounting policies for segment reporting and our consolidated results of operations.

Substantially all of our sales to Kingston were included in our CNBU and SBU segments, substantially all of our sales to Intel were included in our SBU segment, and substantially all of our sales to HP were included in our CNBU and SBU segments. Certain of the raw materials and production equipment we use in manufacturing semiconductor products are available from multiple sources and in sufficient supply; however, only a limited number of suppliers are capable of delivering certain raw materials and production equipment that meet our standards. In some cases, materials are provided by a single supplier. Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash, money market accounts, certificates of deposit, fixed-rate debt securities, trade receivables, and derivative contracts. We invest through high-credit-quality financial institutions and, by policy, generally limit the concentration of credit exposure by restricting investments with any single obligor. A concentration of credit risk may exist with respect to receivables as a substantial portion of our customers are affiliated with the computing industry. We perform ongoing credit evaluations of customers worldwide and generally do not require collateral from our customers. Historically, we have not experienced significant losses on receivables. A concentration of risk may also exist with respect to derivatives as the number of counterparties to our currency hedges is limited and the notional amounts are relatively large. We seek to mitigate such risk by limiting our counterparties to major financial institutions and through entering into master netting arrangements. Capped calls expose us to credit risk to the extent the counterparties may be unable to meet the terms of the agreements. We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading the risk across several major financial institutions. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored on an ongoing basis.

MICRON TECHNOLOGY, INC. SCHEDULE I CONDENSED FINANCIAL INFORMATION OF THE REGISTRANT NOTES TO CONDENSED FINANCIAL STATEMENTS (All tabular amounts in millions) Basis of Presentation Micron, a Delaware corporation, was incorporated in 1978. Micron is the parent company of its consolidated subsidiaries and, together with its consolidated subsidiaries, is a global leader in advanced semiconductor systems. These condensed financial statements have been prepared on a parent-only basis. Under this parent-only presentation, Micron's investments in its consolidated subsidiaries are presented under the equity method of accounting. In accordance with Rule 12-04 of Regulation S-X, these parent-only financial statements do not include all of the information and footnotes required by Generally Accepted Accounting Principles (GAAP) in the United States for annual financial statements. Because these parent-only financial statements and notes do not include all of the information and footnotes required by GAAP in the U.S. for annual financial statements, these parent-only financial statements and other information included should be read in conjunction with Micron's audited Consolidated Financial Statements contained within Part II, Item 8 of this Form 10-K for the year ended September 3, 2015 . Effective in the fourth quarter of 2015, Micron adopted ASU 2015-03 – Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, as appropriate, consistent with debt discounts, as opposed to an asset. The new accounting standard required retrospective application; therefore, Micron's financial statements and notes to those statements contained herein have been adjusted to reflect the impact of adopting this new accounting standard. Debt 2015 2014 Instrument (1) Stated Rate Effective Rate Current Long-Term Total Current Long-Term Total Capital lease obligations (2) N/A N/A $ 174 $ 40 $ 214 $ 172 $ 233 $ 405 2022 senior notes 5.875 % 6.14 % — 589 589 — 587 587 2023 senior notes 5.250 % 5.43 % — 988 988 — — — 2024 senior notes 5.250 % 5.38 % — 545 545 — — — 2025 senior notes 5.500 % 5.56 % — 1,138 1,138 — 1,137 1,137 2026 senior notes 5.625 % 5.73 % — 446 446 — — — 2031B convertible senior notes (3) 1.875 % 6.98 % — — — 361 — 361 2032C convertible senior notes (4) 2.375 % 5.95 % — 197 197 — 309 309 2032D convertible senior notes (4) 3.125 % 6.33 % — 150 150 — 284 284 2033E convertible senior notes (4) 1.625 % 4.50 % 217 — 217 272 — 272 2033F convertible senior notes (4) 2.125 % 4.93 % 264 — 264 260 — 260 2043G convertible senior notes 3.000 % 6.76 % — 644 644 — 631 631 Other 1.654 % 1.65 % — 60 60 — 10 10 $ 655 $ 4,797 $ 5,452 $ 1,065 $ 3,191 $ 4,256 (1) Micron has either the obligation or the option to pay cash for the principal amount due upon conversion for all of its convertible notes. Micron's current intent is to settle in cash the principal amount of all of its convertible notes upon conversion. (2) Weighted-average imputed rate of 4.5% and 4.7% as of September 3, 2015 and August 28, 2014 , respectively. (3) Amount recorded for 2014 included the debt and equity components. The equity component was reclassified to a debt liability as a result of Micron's obligation to settle the conversions of the 2031B Notes in cash. (4) Since the closing price of Micron's common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the initial conversion price per share, holders have the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of Micron's common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes. Micron's convertible and senior notes are unsecured obligations that rank equally in right of payment with all of Micron's other existing and future unsecured indebtedness, and are effectively subordinated to all of Micron's other existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness. The convertible notes and the 2022 Notes, 2023 Notes, 2024 Notes, 2025 Notes, and 2026 Notes of Micron are structurally subordinated to all liabilities of its subsidiaries, including trade payables. Micron guarantees certain debt obligations of its subsidiaries. Micron does not guarantee the MMJ creditor installment payments. As of September 3, 2015 , Micron had guaranteed $655 million of debt obligations of its subsidiaries. Micron's guarantees of its subsidiary debt obligations are unsecured obligations ranking equally in right of payment with all of its other existing and future unsecured indebtedness. Capital Lease Obligations Micron has various capital lease obligations due in periodic installments with a weighted-average remaining term of 1 year. As of September 3, 2015 and August 28, 2014 , Micron had production equipment with carrying values of $140 million and $305 million , respectively, under capital leases. Convertible Senior Notes and Other Senior Notes For further information, see "Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Debt" of Micron's consolidated financial statements. Other Facilities Micron has a credit facility with an aggregate revolving commitment which is subject to certain adjustments, including an availability block that effectively limits the maximum amount Micron could draw to $540 million . As of September 3, 2015 , $50 million of principal was outstanding under this facility and $270 million was available for Micron to draw. For further information, see "Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Debt – Other Facilities – Revolving Credit Facilities" of Micron's consolidated financial statements. Maturities of Notes Payable and Future Minimum Lease Payments As of September 3, 2015 , maturities of notes payable and future minimum lease payments under capital lease obligations were as follows: Notes Payable Capital Lease Obligations 2016 $ — $ 179 2017 — 30 2018 233 3 2019 224 3 2020 347 3 2021 and thereafter 4,854 3 Unamortized discounts and interest, respectively (420 ) (7 ) $ 5,238 $ 214 Commitments Micron has provided various financial guarantees issued in the normal course of business on behalf of its subsidiaries. These contracts include debt guarantees and guarantees on certain banking facilities. Micron enters into these arrangements to facilitate commercial transactions with third parties by enhancing the value of the transaction to the third party. Micron has entered into agreements covering certain activities of its subsidiaries, and occasionally Micron may be required to perform under such agreements on behalf of its subsidiaries. As of September 3, 2015 , the maximum potential amount of future payments Micron could have been required to make under its debt guarantees was approximately $655 million . Substantially all of this amount relates to guarantees for debt of wholly-owned entities whereby Micron would be obligated to perform under the guarantee if a subsidiary were to default on the terms of their debt arrangements. In the event of performance under the guarantee, Micron would be permitted to seek reimbursement from the subsidiary company(s) through liquidation of the assets which were collateral under various debt instruments. At the time these contracts were entered into, the collateralized assets approximated the value of the outstanding guarantees. The majority of these guarantees expire at various times between March 2016 and February 2020 . Micron guarantees a credit facility of a subsidiary that provides for up to $750 million of financing. As of September 3, 2015 , $75 million of principal amount was outstanding under this facility. Micron guarantees certain banking facilities for its wholly-owned consolidated entities. Substantially all of these guarantees relate to bank overdraft protections. The maximum potential amount of future payments Micron could be required to make under these guarantees varies based on the extent of potential overdrafts. Micron's business processes substantially mitigate the risk of wholly-owned subsidiaries overdrafting their bank accounts. The majority of these guarantees have no contractual expiration. Contingencies As is typical in the semiconductor and other high technology industries, from time to time others have asserted, and may in the future assert, that Micron and its subsidiaries' products or manufacturing processes infringe their intellectual property rights. Micron has accrued a liability and charged operations for the estimated costs of adjudication or settlement of various asserted and unasserted claims existing as of the balance sheet date. Micron is currently a party to various litigation regarding patent, commercial, and other matters. Micron is a party to the matters listed in the "Contingencies" note in the consolidated financial statements. For further information, see "Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Contingencies" of Micron's consolidated financial statements. Redeemable Convertible Notes For further information, see "Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Redeemable Convertible Notes" of Micron's consolidated financial statements. Related Party Transactions Substantially all of Micron's activities relate to manufacturing services performed for a subsidiary and to royalties received from its subsidiaries for use of product and process technology. Micron's net sales to consolidated subsidiaries were $5.42 billion , $5.64 billion , and $4.19 billion for 2015 , 2014 , and 2013 , respectively. Gross margins on manufacturing activities are commensurate with market rates for such services. Transactions between Micron and its consolidated subsidiaries are eliminated in consolidation. Micron engages in various transactions with its equity method investees and eliminates the profits or losses on those transactions to the extent of its ownership interest until such time as the profits or losses are realized. Micron held an equity interest in Aptina through August 15, 2014. Net sales for 2014 and 2013 included $43 million and $182 million , respectively, from products sold to and services performed for Aptina. On August 15, 2014, ON Semiconductor Corporation acquired Aptina for approximately $433 million and Micron recognized a non-operating gain of $119 million on the sale of its shares based on its diluted ownership interest of approximately 27% . The gain approximated Micron's share of the consideration because the carrying value of its investment had been reduced to zero since the second quarter of 2012, at which time Micron ceased recognizing its proportionate share of Aptina's losses. For further information regarding transactions between Micron and its equity method investees, see "Part II – Item 8. Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Equity Method Investments – Other" of Micron's consolidated financial statements.

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements include the accounts of Micron Technology, Inc. and its consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America.
Reclassifications	Certain reclassifications have been made to prior period amounts to conform to current period presentation. In addition, amounts for certain equipment purchases were reclassified from financing to investing within the statement of cash flows to better reflect the current nature of these transactions and to improve comparability with our industry peers. In the fourth quarter of 2015, we adopted, on a retrospective basis, Accounting Standards Update 2015-03 – Simplifying the Presentation of Debt Issuance Costs. (See "Debt – Retrospective Application of a New Accounting Standard" note.)
Fiscal Period	Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Fiscal year 2015 contained 53 weeks and fiscal years 2014 and 2013 each contained 52 weeks. All period references are to our fiscal periods unless otherwise indicated.
Derivative and Hedging Instruments	Derivative and Hedging Instruments: We use derivative instruments to manage a portion of our exposure to changes in currency exchange rates from our monetary assets and liabilities or future cash flows and to reduce volatility in our earnings caused by changes in interest rates that affect our variable-rate debt. Our derivatives have consisted of forward and option contracts and we have also entered into interest rate swap contracts. We do not use derivative instruments for trading or speculative purposes. Derivative instruments are measured at their fair values and recognized as either assets or liabilities. The accounting for changes in the fair value of derivative instruments is based on the intended use of the derivative and the resulting designation. For derivative instruments that are not designated as hedges for accounting purpose, gains or losses from changes in fair values are recognized in other non-operating income (expense). For derivative instruments designated as cash-flow hedges, the effective portion of the gain or loss is included as a component of other comprehensive income (loss), and the ineffective or excluded portion of the gain or loss is included in other non-operating income (expense). The amounts in accumulated other comprehensive income (loss) from these cash flow hedges are reclassified into earnings in the same line items of the consolidated statements of operation and in the same periods in which the underlying transactions affect earnings. Effectiveness is measured by comparing the cumulative change in the fair value of the hedge contract with the cumulative change in the forecasted cash flows of the hedged item. For the effectiveness assessment of our cash-flow hedges, changes in the time value are excluded for forward contracts. We enter into master netting arrangements with our counterparties to mitigate credit risk in derivative hedge transactions. These master netting arrangements allow us and our counterparties to net settle amounts owed to each other. Derivative assets and liabilities that can be net settled with each counterparty have been presented in our consolidated balance sheet on a net basis. (See "Derivative Instruments" note.)
Cash and Cash Equivalents	Financial Instruments: Cash equivalents include highly liquid short-term investments with original maturities to us of three months or less that are readily convertible to known amounts of cash.
Investments	Investments with maturities greater than three months and less than one year are included in short-term investments. Investments with remaining maturities greater than one year are included in long-term marketable investments. The carrying value of investment securities sold is determined using the specific identification method.
Functional Currency	Functional Currency: The U.S. dollar is the functional currency for all of our consolidated subsidiaries.
Inventories	Inventories: Inventories are stated at the lower of average cost or net realizable value. Cost includes depreciation, labor, material, and overhead costs, including product and process technology costs. Determining net realizable value of inventories involves numerous judgments, including projecting future average selling prices, sales volumes, and costs to complete products in work in process inventories. When net realizable value is below cost, we record a charge to cost of goods sold to write down inventories to their estimated net realizable value in advance of when the inventories are actually sold. Inventories are primarily categorized as memory (including DRAM, non-volatile, and other memory) for purposes of determining the lower of average cost or net realizable value. The major characteristics considered in determining inventory categories for purposes of determining the lower of cost or net realizable value are product type and markets. We remove amounts from inventory and charge such amounts to cost of goods sold on an average cost basis.
Product and Process Technology	Product and Process Technology: Costs incurred to (1) acquire product and process technology, (2) patent technology, and (3) maintain patent technology are capitalized and amortized on a straight-line basis over periods ranging up to 12.5 years. We capitalize a portion of the costs incurred to patent technology based on historical and projected patents issued as a percent of patents we file. Capitalized product and process technology costs are amortized over the shorter of (1) the estimated useful life of the technology, (2) the patent term, or (3) the term of the technology agreement. Fully-amortized assets are removed from product and process technology and accumulated amortization.
Product Warranty	Product Warranty: We generally provide a limited warranty that our products are in compliance with our specifications existing at the time of delivery. Under our general terms and conditions of sale, liability for certain failures of product during a stated warranty period is usually limited to repair or replacement of defective items or return of, or a credit with respect to, amounts paid for such items. Under certain circumstances, we provide more extensive limited warranty coverage than that provided under our general terms and conditions. Our warranty obligations are not significant.
Property, Plant and Equipment	Property, Plant and Equipment: Property, plant, and equipment is stated at cost and depreciated using the straight-line method over estimated useful lives of generally 10 to 30 years for buildings, 5 to 7 years for equipment, and 3 to 5 years for software. Assets held for sale are carried at the lower of cost or estimated fair value and are included in other noncurrent assets. When property, plant, or equipment is retired or otherwise disposed, the net book value is removed and we recognize any gain or loss in our results of operations. We capitalize interest on borrowings during the period of time over which we carry out the activities necessary to bring the asset to the condition of its intended use and location. Capitalized interest becomes part of the cost of the underlying assets and amortized over the useful lives of the assets.
Research and Development	Research and Development: Costs related to the conceptual formulation and design of products and processes are expensed as research and development as incurred. Determining when product development is complete requires judgment. Development of a product is deemed complete once the product has been thoroughly reviewed and has passed tests for performance and reliability. Subsequent to product qualification, product costs are valued in inventory. Product design and other research and development costs for certain technologies are shared with our joint venture partners. Amounts receivable from cost-sharing arrangements are reflected as a reduction of research and development expense. (See "Equity – Noncontrolling Interests in Subsidiaries – IMFT" note.)
Revenue Recognition	Revenue Recognition: We recognize product or license revenue when persuasive evidence that a sales arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. If we are unable to reasonably estimate returns or the price is not fixed or determinable, sales made under agreements allowing rights of return or price protection are deferred until customers have resold the product.
Stock-based Compensation	Stock-based Compensation: Stock-based compensation is measured at the grant date, based on the fair value of the award, and recognized as expense under the straight-line attribution method over the requisite service period. We issue new shares upon the exercise of stock options or conversion of share units. (See "Equity Plans" note.)
Treasury Stock	Treasury Stock: When we retire our treasury stock, any excess of the repurchase price paid over par value is allocated between additional capital and retained earnings.
Use of Estimates	Use of Estimates: The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires our management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures. Estimates and judgments are based on historical experience, forecasted events, and various other assumptions that we believe to be reasonable under the circumstances. Estimates and judgments may differ under different assumptions or conditions. We evaluate our estimates and judgments on an ongoing basis. Actual results could differ from estimates.

Variable Interest Entities (Pol

Variable Interest Entities (Policies)	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	We have interests in entities that are VIEs. If we are the primary beneficiary of a VIE, we are required to consolidate it. To determine if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing, and other applicable agreements and circumstances. Our assessments of whether we are the primary beneficiary of our VIEs require significant assumptions and judgments.

Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method. (2) Weighted-average imputed rate of 3.7% and 4.3% as of September 3, 2015 and August 28, 2014 , respectively. (3) Amount recorded for 2014 included the debt and equity components. The equity component was reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash. (4) Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the conversion price per share, holders had the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes. 2015 2014 As of Expected Remaining Term (Years) (1) Outstanding Principal Unamortized Discount and Debt Issuance Costs Net Carrying Amount Outstanding Principal Unamortized Discount and Debt Issuance Costs Net Carrying Amount MMJ creditor installment payments 4 $ 1,012 $ (150 ) $ 862 $ 1,369 $ (238 ) $ 1,131 Capital lease obligations 4 792 — 792 911 — 911 1.258% notes 3 323 (19 ) 304 416 (25 ) 391 2022 Notes 6 600 (11 ) 589 600 (13 ) 587 2023 Notes 8 1,000 (12 ) 988 — — — 2024 Notes 8 550 (5 ) 545 — — — 2025 Notes 9 1,150 (12 ) 1,138 1,150 (13 ) 1,137 2026 Notes 10 450 (4 ) 446 — — — 2031B Notes (2) N/A — — — 114 (28 ) 361 2032C Notes 4 224 (27 ) 197 362 (53 ) 309 2032D Notes 6 177 (27 ) 150 344 (60 ) 284 2033E Notes 2 233 (16 ) 217 300 (28 ) 272 2033F Notes 4 297 (33 ) 264 300 (40 ) 260 2043G Notes (3) 13 1,025 (381 ) 644 1,025 (394 ) 631 Other notes payable 4 205 — 205 243 (6 ) 237 $ 8,038 $ (697 ) $ 7,341 $ 7,134 $ (898 ) $ 6,511 (1) Expected remaining term for amortization of the remaining unamortized discount and debt issuance costs as of September 3, 2015 . The expected remaining term of the 2031B Notes was not applicable because the notes were not outstanding as of September 3, 2015 . Expected remaining term for capital lease obligations is the weighted-average remaining term. (2) As holders had elected to convert these notes and we elected to settle the conversions in cash, the net carrying amount for 2014 included the debt component and equity component, which were reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash, resulting in an aggregate liability of $389 million . The outstanding principal reflects the original principal of the 2031B Notes. (3) The 2043G Notes have an original principal amount of $820 million that accretes up to $917 million through the expected term on November 15, 2028 and $1.03 billion at maturity in 2043. The discount is based on the principal at maturity. See "2043G Notes" below.

Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]	Effective in the fourth quarter of 2015, we adopted ASU 2015-03 – Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, as appropriate, consistent with debt discounts, as opposed to an asset. The new accounting standard required retrospective application; therefore, our financial statements and notes to these statements contained herein have been adjusted to reflect the impact of adopting this new accounting standard. The following table sets forth the financial statement line items affected by retrospective application of this new accounting standard: As of August 28, 2014 Previously Reported Effect of Adoption Retrospectively Adjusted Other noncurrent assets $ 497 $ (82 ) $ 415 Current debt 1,638 (20 ) 1,618 Long-term debt 4,955 (62 ) 4,893 Redeemable convertible debt 57 11 68 Additional capital 7,879 (11 ) 7,868

Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method. (2) Weighted-average imputed rate of 3.7% and 4.3% as of September 3, 2015 and August 28, 2014 , respectively. (3) Amount recorded for 2014 included the debt and equity components. The equity component was reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash. (4) Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the conversion price per share, holders had the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes. 2015 2014 As of Expected Remaining Term (Years) (1) Outstanding Principal Unamortized Discount and Debt Issuance Costs Net Carrying Amount Outstanding Principal Unamortized Discount and Debt Issuance Costs Net Carrying Amount MMJ creditor installment payments 4 $ 1,012 $ (150 ) $ 862 $ 1,369 $ (238 ) $ 1,131 Capital lease obligations 4 792 — 792 911 — 911 1.258% notes 3 323 (19 ) 304 416 (25 ) 391 2022 Notes 6 600 (11 ) 589 600 (13 ) 587 2023 Notes 8 1,000 (12 ) 988 — — — 2024 Notes 8 550 (5 ) 545 — — — 2025 Notes 9 1,150 (12 ) 1,138 1,150 (13 ) 1,137 2026 Notes 10 450 (4 ) 446 — — — 2031B Notes (2) N/A — — — 114 (28 ) 361 2032C Notes 4 224 (27 ) 197 362 (53 ) 309 2032D Notes 6 177 (27 ) 150 344 (60 ) 284 2033E Notes 2 233 (16 ) 217 300 (28 ) 272 2033F Notes 4 297 (33 ) 264 300 (40 ) 260 2043G Notes (3) 13 1,025 (381 ) 644 1,025 (394 ) 631 Other notes payable 4 205 — 205 243 (6 ) 237 $ 8,038 $ (697 ) $ 7,341 $ 7,134 $ (898 ) $ 6,511 (1) Expected remaining term for amortization of the remaining unamortized discount and debt issuance costs as of September 3, 2015 . The expected remaining term of the 2031B Notes was not applicable because the notes were not outstanding as of September 3, 2015 . Expected remaining term for capital lease obligations is the weighted-average remaining term. (2) As holders had elected to convert these notes and we elected to settle the conversions in cash, the net carrying amount for 2014 included the debt component and equity component, which were reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash, resulting in an aggregate liability of $389 million . The outstanding principal reflects the original principal of the 2031B Notes. (3) The 2043G Notes have an original principal amount of $820 million that accretes up to $917 million through the expected term on November 15, 2028 and $1.03 billion at maturity in 2043. The discount is based on the principal at maturity. See "2043G Notes" below.

Micron's current intent is to settle in cash the principal amount of all of its convertible notes upon conversion. (2) Weighted-average imputed rate of 4.5% and 4.7% as of September 3, 2015 and August 28, 2014 , respectively. (3) Amount recorded for 2014 included the debt and equity components. The equity component was reclassified to a debt liability as a result of Micron's obligation to settle the conversions of the 2031B Notes in cash. (4) Since the closing price of Micron's common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the initial conversion price per share, holders have the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of Micron's common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes.

[1]	The maturities of our long-term marketable securities generally range from one to four years.
[2]	The fair value of Level 1 securities is measured based on quoted prices in active markets for identical assets.
[3]	The fair value of Level 2 securities is measured using information obtained from pricing services, which obtain quoted market prices for similar instruments, non-binding market consensus prices that are corroborated by observable market data, or various other methodologies, to determine the appropriate value at the measurement date. We perform supplemental analysis to validate information obtained from these pricing services. As of September 3, 2015, no adjustments were made to such pricing information.

[1]	Expected remaining term for amortization of the remaining unamortized discount and debt issuance costs as of September 3, 2015. The expected remaining term of the 2031B Notes was not applicable because the notes were not outstanding as of September 3, 2015. Expected remaining term for capital lease obligations is the weighted-average remaining term.
[2]	Weighted-average imputed rate of 3.7% and 4.3% as of September 3, 2015 and August 28, 2014, respectively.
[3]	Weighted-average imputed rate of 4.5% and 4.7% as of September 3, 2015 and August 28, 2014, respectively.
[4]	If we redeem prior to the applicable date with net cash proceeds of one or more equity offerings, the price is equal to the amount specified above, together with accrued and unpaid interest, subject to a maximum redemption of 35% of the aggregate principal amount of the respective notes being redeemed.
[5]	Micron has either the obligation or the option to pay cash for the principal amount due upon conversion for all of its convertible notes. Micron's current intent is to settle in cash the principal amount of all of its convertible notes upon conversion.
[6]	Based on our closing share price of $16.59 as of September 3, 2015.
[7]	Amount recorded for 2014 included the debt and equity components. The equity component was reclassified to a debt liability as a result of Micron's obligation to settle the conversions of the 2031B Notes in cash.
[8]	As holders had elected to convert these notes and we elected to settle the conversions in cash, the net carrying amount for 2014 included the debt component and equity component, which were reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash, resulting in an aggregate liability of $389 million. The outstanding principal reflects the original principal of the 2031B Notes.
[9]	We have either the obligation or the option to pay cash for the principal amount due upon conversion for all of our convertible notes. Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method.
[10]	Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the conversion price per share, holders had the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes.
[11]	The terms of our convertible notes give holders the right to require us to repurchase all or a portion of their notes at a date prior to the contractual maturities of the notes at a price equal to the principal amount thereof plus accrued interest.
[12]	Holders have the right to convert all or a portion of their notes at a date prior to the contractual maturity if, during any calendar quarter, the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the conversion price. The closing price of our common stock exceeded the thresholds for the calendar quarter ended September 30, 2015 for our 2032 Notes and 2033 Notes; therefore, those notes are convertible by the holders through December 31, 2015.
[13]	Since the closing price of Micron's common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the initial conversion price per share, holders have the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of Micron's common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes.
[14]	The 2043G Notes have an original principal amount of $820 million that accretes up to $917 million through the expected term on November 15, 2028 and $1.03 billion at maturity in 2043. The discount is based on the principal at maturity. See "2043G Notes" below.
[15]	See "2043G Notes."
[16]	Other notes include the 2014 Notes, 2027 Notes, 2031A Notes, and 2031B Notes.

[2]	Included in other non-operating expense.
[3]	As holders had elected to convert these notes and we elected to settle the conversions in cash, the net carrying amount for 2014 included the debt component and equity component, which were reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash, resulting in an aggregate liability of $389 million. The outstanding principal reflects the original principal of the 2031B Notes.
[4]	We have either the obligation or the option to pay cash for the principal amount due upon conversion for all of our convertible notes. Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method.
[5]	The 2043G Notes have an original principal amount of $820 million that accretes up to $917 million through the expected term on November 15, 2028 and $1.03 billion at maturity in 2043. The discount is based on the principal at maturity. See "2043G Notes" below.

[1]	Settlement in cash on the respective expiration dates would result in us receiving an amount ranging from zero, if the market price per share of our common stock is at or below the low strike price, to the maximum amount if the market price per share of our common stock is at or above the high cap price. If share settlement were elected, the number of shares received would be determined by the value of the capped calls at the time of settlement divided by the share price on the settlement date. Settlement of the capped calls prior to the expiration dates may be for an amount less than the maximum value at expiration.

[1]	Weighted-average imputed rate of 3.7% and 4.3% as of September 3, 2015 and August 28, 2014, respectively.
[2]	Expected remaining term for amortization of the remaining unamortized discount and debt issuance costs as of September 3, 2015. The expected remaining term of the 2031B Notes was not applicable because the notes were not outstanding as of September 3, 2015. Expected remaining term for capital lease obligations is the weighted-average remaining term.
[3]	Amount recorded for 2014 included the debt and equity components. The equity component was reclassified to a debt liability as a result of Micron's obligation to settle the conversions of the 2031B Notes in cash.
[4]	As holders had elected to convert these notes and we elected to settle the conversions in cash, the net carrying amount for 2014 included the debt component and equity component, which were reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash, resulting in an aggregate liability of $389 million. The outstanding principal reflects the original principal of the 2031B Notes.
[5]	Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the conversion price per share, holders had the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes.
[6]	We have either the obligation or the option to pay cash for the principal amount due upon conversion for all of our convertible notes. Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method.
[7]	The 2043G Notes have an original principal amount of $820 million that accretes up to $917 million through the expected term on November 15, 2028 and $1.03 billion at maturity in 2043. The discount is based on the principal at maturity. See "2043G Notes" below.
[8]	Weighted-average imputed rate of 4.5% and 4.7% as of September 3, 2015 and August 28, 2014, respectively.
[9]	Micron has either the obligation or the option to pay cash for the principal amount due upon conversion for all of its convertible notes. Micron's current intent is to settle in cash the principal amount of all of its convertible notes upon conversion.
[10]	Since the closing price of Micron's common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the initial conversion price per share, holders have the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of Micron's common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes.
