Significant Accounting Policies	Significant Accounting Policies
	Basis of Presentation: We are one of the world's leading providers of advanced semiconductor solutions. Through our worldwide operations, we manufacture and market a full range of DRAM, NAND Flash and NOR Flash memory, as well as other innovative memory technologies, packaging solutions and semiconductor systems for use in leading-edge computing, consumer, networking, automotive, industrial, embedded and mobile products. 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, including restructure and asset impairment activities prior to 2013 that were previously reported in other operating (income) expense, net. In 2013, we reclassified gains and losses from changes in currency exchange rates in order to improve comparability with our industry peers. As a result of the reclassification, $6 million of losses in both 2012 and 2011, were reclassified from the amounts previously reported in other operating (income) expense, net to other non-operating income (expense), net. Certain deferred tax assets and liabilities in prior years were corrected with corresponding changes in the valuation allowance, resulting in no change to net deferred tax assets. The change in these items was not material for any period presented.
	Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Our fiscal years 2013, 2012 and 2011 each contained 52 weeks. All period references are to our fiscal periods unless otherwise indicated. Our recently acquired subsidiary, Elpida Memory, Inc., has been consolidated based on its fiscal year ending on August 31, 2013.
	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.
	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 material.
	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.  Since we are unable to estimate returns and changes in market price, and therefore the price is not fixed or determinable, sales made under agreements allowing pricing protection or rights of return (other than for product warranty) are deferred until customers have resold the product.
	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 these cost-sharing arrangements are reflected as a reduction of research and development expense.  (See "Equity Method Investments" and "Consolidated Variable Interest Entities – IM Flash" notes.)
	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.)
	Stock Repurchases: When we repurchase and retire our common stock, any excess of the repurchase price paid over par value is allocated between paid-in capital and retained earnings.
	Functional Currency: The U.S. dollar is the functional currency for all of our consolidated operations.
	Financial Instruments: Cash equivalents include highly liquid short-term investments with original maturities to us of three months or less, readily convertible to known amounts of cash.  Investments with original maturities greater than three months and remaining maturities 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.
	Derivative and Hedging Instruments: We use derivative financial instruments to manage certain exposures to fluctuating currency exchange and interest rates. Our derivatives consist primarily of forward and option currency contracts and 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) for 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 and included for options.
	We seek to enter into master netting arrangements to mitigate credit risk in derivative 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 under these arrangements have been presented in our consolidated balance sheet on a net basis.
	(See "Derivative Financial Instruments – Currency Derivatives with Hedge Accounting Designation" note.)
	Inventories: Inventories are stated at the lower of average cost or market value.  Cost includes labor, material and overhead costs, including product and process technology costs.  Determining market values of inventories involves numerous judgments, including projecting average selling prices and sales volumes for future periods and costs to complete products in work in process inventories.  When market values are below costs, we record a charge to cost of goods sold to write down inventories to their estimated market value in advance of when the inventories are actually sold.  The major characteristics considered in determining inventory categories for purposes of determining the lower of cost or market value are product type and markets. Prior to the third quarter of 2013, inventory was categorized as memory (primarily DRAM and NAND Flash and NOR Flash) and imaging products for purposes of determining lower of average cost or market. Due to the sale on May 3, 2013 of Micron Technology Italia, S.r.l. ("MIT") and our assignment to LFoundry Marsica S.r.l. ("LFoundry") of our supply agreement with Aptina Imaging Corporation ("Aptina") for CMOS image sensors, we ceased manufacturing CMOS image sensors subsequent to that date and no longer have imagining inventory for purposes of determining lower of average cost or market.
	Product and Process Technology: Costs incurred to acquire product and process technology or to patent technology are capitalized and amortized on a straight-line basis over periods ranging up to 10 years.  We capitalize a portion of costs incurred based on the historical and projected patents issued as a percent of patents we file.  Capitalized product and process technology costs are amortized over the shorter of (i) the estimated useful life of the technology, (ii) the patent term or (iii) the term of the technology agreement.  Fully-amortized assets are removed from product and process technology and accumulated amortization.
	Property, Plant and Equipment: Property, plant and equipment are stated at cost and depreciated using the straight-line method over estimated useful lives of generally 10 to 30 years for buildings, generally 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 or equipment is retired or otherwise disposed, the net book value of the asset is removed and we recognize any gain or loss in our results of operations.
	We capitalize interest on borrowings during the active construction period of capital projects.  Capitalized interest is added to the cost of the underlying assets and amortized over the useful lives of the assets.

Variable Interest Entities	Variable Interest Entities
	We have interests in entities that are Variable Interest Entities ("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 Variable Interest Entities
	Inotera: Inotera Memories, Inc. ("Inotera") is a VIE because its equity is not sufficient to permit it to finance its activities without additional support from its shareholders. In the second quarter of 2013, we entered into agreements with Nanya Technology Corporation ("Nanya") and Inotera to amend the joint venture relationship involving Inotera, including a new supply agreement between us and Inotera. 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 (1) limitations on our governance rights that require the consent of other parties for key operating decisions and (2) 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.
	Transform: Transform Solar Pty Ltd. ("Transform") is a VIE because its equity is not sufficient to permit it to finance its activities without additional financial support from us or its parent, Origin Energy Limited ("Origin"). We have determined that we do not have the power to direct the activities of Transform that most significantly impact its economic performance, primarily due to limitations on our governance rights that require the consent of Origin for key operating decisions. Therefore, we do not consolidate Transform and we account for our interest under the equity method. As of August 30, 2012, Transform's operations were substantially discontinued.
	For further information regarding our VIEs that we account for under the equity method, see "Equity Method Investments" note.
	EQUVO Entities: EQUVO HK Limited and EQUVA Capital 1 Pte. Ltd. (together, the "EQUVO Entities") are special purpose entities created to facilitate equipment sale-leaseback financing transactions between us and a consortium of financial institutions that fund the sale-leaseback transactions ("Financing Entities"). Neither we nor the Financing Entities have an equity interest in the EQUVO Entities. The EQUVO Entities are VIEs because their equity is not sufficient to permit them to finance their 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 arrangements with the EQUVO Entities are merely financing vehicles and we do not bear any significant risks from variable interests with the EQUVO Entities. Therefore, we have determined that we do not have the power to direct the activities of the EQUVO Entities that most significantly impact their economic performance and we do not consolidate the EQUVO Entities.
	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 impacts its economic performance. Therefore, we do not consolidate SCHE.
	Consolidated Variable Interest Entities
	IMFT: IM Flash Technologies, LLC ("IMFT") is a VIE because all of its costs are passed to us and its other member, Intel Corporation ("Intel"), through product purchase agreements and IMFT is dependent upon us or Intel for any additional cash requirements.  We determined that we have the power to direct the activities of IMFT that most significantly impact its economic performance.  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 also determined that we have the obligation to absorb losses and the right to receive benefits from IMFT that could potentially be significant to it.  Therefore, we consolidate IMFT.
	IMFS: Prior to April 6, 2012, IM Flash Singapore, LLP ("IMFS") was a VIE because all of its costs were passed to us and its other member, Intel, through product purchase agreements and IMFS was dependent upon us or Intel for any additional cash requirements.  Prior to April 6, 2012, we determined that we had the power to direct the activities of IMFS that most significantly impacted its economic performance.  Additionally, since 2010, we had significantly greater economic exposure than Intel as a result of our significantly higher ownership interest in IMFS.  Therefore, we consolidated IMFS. On April 6, 2012, we acquired Intel's remaining interests in IMFS and it ceased to be a VIE.
	MP Mask: MP Mask Technology Center, LLC ("MP Mask") is a VIE because substantially all of its costs are passed to us and its other member, Photronics, Inc. ("Photronics"), through product purchase agreements and MP Mask is dependent upon us or Photronics for any additional cash requirements.  We determined that we have the power to direct the activities of MP Mask that most significantly impact its economic performance, primarily because (1) of our tie-breaking voting rights over key operating decisions and (2) nearly all key MP Mask activities are driven by our supply needs.  We also determined that we have the obligation to absorb losses and the right to receive benefits from MP Mask that could potentially be significant to it.  Therefore, we consolidate MP Mask.
	For further information regarding our consolidated VIEs, see "Consolidated Variable Interest Entities" note.

	On July 31, 2013, we completed the acquisition of Elpida Memory, Inc., a Japanese corporation, pursuant to the terms and conditions of an Agreement on Support for Reorganization Companies (as amended, the "Sponsor Agreement") that we entered into on July 2, 2012, with the trustees of Elpida and one of its subsidiaries, Akita Elpida Memory, Inc., a Japanese corporation ("Akita" and, together with Elpida, the "Elpida Companies") pursuant to and in connection with the Elpida Companies' corporate reorganization proceedings under the Corporate Reorganization Act of Japan. We paid $615 million for the acquisition of Elpida, of which substantially all was deposited into accounts that are legally restricted for payment to the secured and unsecured creditors of the Elpida Companies in October 2013. As of August 29, 2013, the amount held in the restricted accounts was presented as restricted cash. Of the $615 million paid at closing, $18 million was applied from amounts we had deposited into an escrow account in July 2012 as a condition to the execution of the Sponsor Agreement.
	On July 31, 2013, we also completed the acquisition of an additional 24% ownership interest in Rexchip Electronics Corporation ("Rexchip"), a Taiwanese corporation and manufacturing joint venture formed by Elpida and Powerchip Technology Corporation ("Powerchip") from Powerchip and certain of its affiliates (the "Powerchip Group") pursuant to a share purchase agreement. We paid $334 million in cash for the shares. Elpida owns, directly and indirectly through a subsidiary, approximately 65% of Rexchip's outstanding common stock. Therefore, as a result of the consummation of our acquisition of Elpida and the Rexchip shares from the Powerchip Group, we own approximately 89% ownership interest in Rexchip.
	Elpida's assets include, among others: a 300mm DRAM wafer fabrication facility located in Hiroshima, Japan; its approximate 65% ownership interest in Rexchip, whose assets include a 300mm DRAM wafer fabrication facility located in Taichung City, Taiwan; and a 100% ownership interest in Akita, whose assets include an assembly and test facility located in Akita, Japan. Elpida's semiconductor memory products include mobile DRAM targeted toward mobile phones and tablets. We believe that combining the complementary product portfolios of Micron and Elpida strengthens our position in the memory market and enables us to provide customers with a wider portfolio of high-quality memory solutions. We also believe that our acquisition of Elpida strengthens our market position in the memory industry through increased research and development and manufacturing scale, improved access to core memory market segments, and additional wafer capacity to balance among our DRAM, NAND Flash and NOR Flash memory solutions.
	The Elpida Acquisition and Rexchip share purchase are treated as a single business combination because (1) the two transactions were entered into and closed contemporaneously and (2) the Rexchip share purchase was negotiated in contemplation of the Elpida acquisition and its completion was contingent on the closing of the Elpida acquisition.
	We estimated the provisional fair value of the assets and liabilities of Elpida and it's subsidiaries (the "Elpida 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. These provisional amounts could change as additional information becomes available.
	The consideration and provisional valuation of assets acquired and liabilities assumed are 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	(387		)
	Equipment purchase contracts	(22		)
	Current portion of long-term debt	(673		)
	Long-term debt	(1,461		)
	Other noncurrent liabilities	(75		)
	Total net assets acquired	2,601
	Noncontrolling interests in Elpida:	168
	Consideration	949
	Gain on acquisition	$	1,484
	Because the fair value of the net assets acquired less noncontrolling interests exceeded the purchase price, we recognized a gain on the acquisition of $1,484 million.  The yen-denominated purchase price was fixed on July 2, 2012 when we entered into the Sponsor Agreement. We believe the fair value exceeded the purchase price because of increases in working capital from improvements in market conditions in the DRAM industry between July 2, 2012 and July 31, 2013, when we completed the acquisition. These conditions resulted in significant increases in U.S. dollar equivalent net assets of Elpida.
	The fair value of the noncontrolling interest in the table above primarily relates to Rexchip and was derived based on the purchase price we paid the Powerchip Group for their 24% ownership interest.
	Our results of operations for 2013 include $355 million of net sales and $46 million of operating income (losses) from the Elpida operations after the July 31, 2013 acquisition date. Included in the selling, general and administrative expenses in the results of operations for 2013 are transaction costs of $50 million incurred in connection with this acquisition.
	As a result of the Japan Proceedings, for so long as such proceedings are continuing, the Elpida Companies and their subsidiaries are subject to certain restrictions on dividends, loans and advances. The plans of reorganization of the Elpida Companies prohibit the Elpida Companies from paying dividends, including any cash dividends, to us and require that excess earnings be used in their businesses or to fund the Elpida Companies' installment payments. These prohibitions would also effectively prevent the subsidiaries of the Elpida Companies from paying cash dividends to us as any such dividends would have to be first paid to the Elpida 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 Elpida 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 Elpida Companies may be considered outside of the ordinary course of business and subject to approval of the legal trustees and Japan Court. As a result, the assets of the Elpida Companies and their subsidiaries, while available to satisfy the Elpida Companies' installment payments and the other obligations, capital expenditures and other operating needs of the Elpida Companies and their subsidiaries, are not available for use by us in our other operations. Moreover, certain uses of the assets of the Elpida Companies, including investments in certain capital expenditures and in Rexchip, may require consent of Elpida's trustees and/or the Japan Court.
	Total net assets, less noncontrolling interests, of the Elpida Companies and their subsidiaries as of August 29, 2013 were $2,460 million. As of August 29, 2013, the Elpida Companies held cash and equivalents of $1,094 million and $556 million of current restricted cash, none of which were available for cash dividends, loans or advances as a result of the above-described restrictions. The restricted cash was held in accounts that are controlled by the trustees and are legally restricted for payment of secured and unsecured creditors of the Elpida Companies pursuant to the plans of reorganization.

	Transform began using the liquidation basis of accounting in June 2012. Transform's statement of net assets (liabilities) in liquidation included $9 million of assets and $8 million of liabilities as of August 29, 2013 and $29 million of assets and $14 million of liabilities as of August 30, 2012, which were excluded from the table above. Additionally, Transform's statement of changes in net assets (liabilities) in liquidation for the fourth quarter of 2012 included a decrease in the estimated fair values of net assets of $67 million. Activity for 2013 was not significant. (See "Transform" below).
	As of August 29, 2013, our maximum exposure to loss from our involvement with our equity method investments that were VIEs was $344 million and primarily included our Inotera investment balance.  We may also incur losses in connection with our rights and obligations to purchase substantially all of Inotera's wafer production capacity under a supply agreement with Inotera.
	Inotera
	We have partnered with Nanya in Inotera, a Taiwanese DRAM memory company, since the first quarter of 2009.  In March 2012, we contributed $170 million to Inotera, which increased our ownership percentage to 40%. On May 28, 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 (approximately $0.32 U.S. dollars), which was in excess of our carrying value per share. As a result of the issuance, our ownership interest decreased to 35% and we recognized a gain of $48 million in 2013. As of August 29, 2013, we held a 35% ownership interest in Inotera, Nanya and certain of its affiliates held a 36% ownership interest and the remaining ownership interest was publicly held.
	As of August 29, 2013 the market value of our equity interest in Inotera was $854 million based on the closing trading price of its shares in an active market. As of August 29, 2013 and August 30, 2012, there were gains of $44 million and $49 million, respectively, in accumulated other comprehensive income (loss) for cumulative translation adjustments from our equity investment in Inotera.
	The net carrying value of our initial and subsequent investments was less than our proportionate share of Inotera's equity at the time of those investments.  These differences are being amortized as a net credit to earnings through equity in net income (loss) of equity method investees (the "Inotera Amortization").  For both 2012 and 2011, we recognized $48 million of Inotera Amortization. As of August 30, 2012, the remaining amount of unrecognized Inotera Amortization was not significant.
	As of June 30, 2013, Inotera's current liabilities exceeded its current assets by $1.0 billion, which exposes Inotera to liquidity risk. Additionally, Inotera incurred net losses of $541 million for its fiscal year ended December 31, 2012. As of June 30, 2013, Inotera was not in compliance with certain of its loan covenants, and had not been in compliance for the past several years, which may result in its lenders requiring repayment of such loans during the next year. Inotera has applied for a waiver from complying with the June 30, 2013 financial covenants. Inotera's management has implemented plans to improve its liquidity and for Inotera's six-month period ended June 30, 2013, Inotera generated net income of $91 million; however, there can be no assurance that Inotera will be successful in sufficiently improving its liquidity and complying with their loan covenants, which may result in its lenders requiring repayment of such loans during the next year.
	In the second quarter of 2012, we loaned $133 million to Inotera under a 90-day note with a stated annual interest rate of 2% to facilitate the purchase of capital equipment necessary to implement new process technology. The loan was repaid to us with accrued interest in March 2012.
	On January 17, 2013, we entered into agreements with Nanya and Inotera to amend the joint venture relationship involving Inotera. The amendments included a new supply agreement (the "Inotera Supply Agreement"), retroactively effective beginning on January 1, 2013, between us and Inotera under which we are obligated to purchase for an initial period through January, 2016, substantially all of Inotera's output at a purchase price based on a discount from market prices for our comparable components. The Inotera Supply Agreement contemplates annual negotiations with respect to potential successive one-year extensions and if in any year the parties do not agree to an extension, the agreement will terminate following the end of the then-existing term plus a subsequent three-year wind-down period. Our share of Inotera's capacity would decline over the three year wind-down period. Under applicable accounting guidance, the Inotera Supply Agreement is treated as containing an embedded operating lease with respect to Inotera's production assets during the initial three-year term of the lease. Effective through December 31, 2012, we had rights and obligations to purchase 50% of Inotera's wafer production capacity based on a margin-sharing formula among Nanya, Inotera and us. Under these agreements, we purchased $1,260 million, $646 million, and $641 million of DRAM products in 2013, 2012 and 2011 respectively. In 2012, we recognized losses on our purchase commitment under the Inotera Supply Agreement of $17 million, $19 million and $40 million in our fourth, second and first quarters, respectively. In 2011, we recognized purchase commitment losses of $28 million, $3 million, $12 million and $11 million in the fourth, third, second and first quarters, respectively.
	Under a cost-sharing arrangement effective through December 31, 2012, we generally shared DRAM process and design development costs with Nanya. As a result of the January 17, 2013 agreements, which were retroactively effective beginning on January 1, 2013, Nanya no longer participates in the joint development program. Pursuant to the cost-sharing arrangement, our research and development ("R&D") costs were reduced by $19 million, $138 million, and $141 million in 2013, 2012 and 2011, respectively.  In addition, we recognized royalty revenue from Nanya of $3 million, $11 million, and $25 million in 2013, 2012 and 2011, respectively, for sales of DRAM products manufactured by or for Nanya on process nodes of 50nm or higher.
	Tera Probe
	On July 31, 2013, we acquired, as an asset of Elpida, a 40% interest in Tera Probe, Inc. ("Tera Probe"), a Japanese-based company mainly engaged in wafer testing and contract wafer-level package testing services. Our investment in Tera Probe was valued at $40 million, based on the aggregate trading price of the shares in an active market on the acquisition date (Level 1 fair value measurements). The net carrying value of our investment was less than our proportionate share of Tera Probe's equity at the time of our investment, and the difference is being amortized as a net credit to earnings through equity in net income (loss) of equity method investees (the "Tera Probe Amortization"). As of August 29, 2013, $35 million of unamortized Tera Probe Amortization was being recognized over a weighted-average period of 7 years.
	As of August 29, 2013, based on the closing trading price of Tera Probe's shares in an active market, the market value of our equity interest was $30 million. We evaluated our investment in Tera Probe and concluded that the decline in the market value below carrying value was not an other-than-temporary impairment primarily because of the limited amount of time the fair value was below the carrying value, the subsequent recovery and historical volatility of the stock price.
	Tera Probe performs probe services for certain of our manufacturing processes. Included in cost of goods sold for 2013 is $13 million for probe services performed by Tera Probe.
	Other
	Transform: In the second quarter of 2010, we acquired a 50% interest in Transform, a developer, manufacturer and marketer of photovoltaic technology and solar panels, from Origin. As of August 29, 2013, we and Origin each held a 50% ownership interest in Transform.  As a result of the ongoing challenging global environment in the solar industry and unfavorable worldwide supply and demand conditions, on May 25, 2012, the Board of Directors of Transform approved a liquidation plan. As a result of the liquidation plan, we recognized a charge of $69 million in 2012. As of August 30, 2012, Transform's operations were substantially discontinued.
	Other noncurrent assets as of August 30, 2012 included $26 million for a portion of our Boise, Idaho manufacturing facilities leased to Transform and other noncurrent liabilities included $26 million for deferred rent revenue on the fully-paid lease. In 2013, Transform terminated the lease and, as a result, we recognized a gain of $25 million from the termination.
	During 2012 and 2011, we and Origin each contributed $17 million and $30 million, respectively, of cash to Transform.  We recognized net sales of $13 million and $20 million in 2012 and 2011, respectively, for transition services provided to Transform. Revenue on our sales to Transform approximated costs. Revenue and associated costs for 2013 were not significant.
	Aptina: Other equity method investments included a 31% equity interest in Aptina. The amount of cumulative loss we recognized from our investment in Aptina through the second quarter of 2012 reduced our investment balance to zero and we ceased recognizing our proportionate share of Aptina's losses.
	Through May 3, 2013, we manufactured components for CMOS image sensors for Aptina under a wafer supply agreement.  For 2013, 2012 and 2011, we recognized net sales of $182 million, $372 million and $349 million, respectively, from products sold to Aptina, and cost of goods sold of $219 million, $395 million and $358 million, respectively. On May 3, 2013, we assigned to LFoundry our supply agreement with Aptina to manufacture image sensors at our 200mm Avezzano facility. (See "Restructure and Asset Impairments - Micron Technology Italia, S.r.l." note.)
	In connection with the sale of our 200mm Avezzano facility to LFoundry, on May 22, 2013, we entered into a short-term, interest-free, unsecured loan agreement with Aptina that allowed Aptina to borrow up to $45 million, drawn at their option, in three equal tranches through July 2013. Principal amounts drawn are due in three equal payments from September 2013 to January 2014. As of August 29, 2013, other current assets included $45 million for amounts due under the short-term loan agreement.

	Our senior notes are unsecured obligations ranking 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.  The convertible notes and the Intel note of Micron Technology, Inc. ("MTI") of $2,531 million are structurally subordinated to $1,863 million of other notes payable of its subsidiaries and capital lease obligations.  MTI guarantees certain debt obligations of its subsidiaries. MTI does not guarantee the Elpida creditor installment payments.  MTI'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.
	Elpida Creditor Installment Payments
	The Elpida Companies are currently subject to corporate reorganization proceedings under the Corporate Reorganization Act of Japan. Both of the Elpida Companies have adopted plans of reorganization which set forth the treatment of the Elpida Companies' pre-petition creditors and their claims, which plans were approved by the Elpida Companies' creditors and the Tokyo District Court in February 2013. Under Elpida's plan of reorganization, secured creditors will recover 100% of the amount of their fixed claims and unsecured creditors will recover at least 17.4% of the amount of their fixed claims. The actual recovery of unsecured creditors will be higher, however, based on events and circumstances that occur following the plan approval. The remaining portion of the unsecured claims will be discharged, without payment, over the period that payments are made pursuant to the plans of reorganization. The plans of reorganization provide for the Elpida Companies' pre-petition creditors to be paid in seven installments. Elpida's secured creditors will be paid in full on or before the sixth installment payment date, while the unsecured creditors will be paid in seven installments. Akita's plan of reorganization provides that secured creditors will recover 100% of the amount of their claims, whereas unsecured creditors will recover at least 19% of the amount of their claims. The secured creditors of Akita will be paid in full on the first installment payment date, while the unsecured creditors will be paid in seven installments.
	Under the terms and conditions of the Elpida Companies' respective plans of reorganization, the Elpida Companies are obligated to pay 200 billion yen (or the equivalent of $2.05 billion based on exchange rates as of August 29, 2013), less certain expenses of their reorganization proceedings and certain other items, to the secured and unsecured creditors (the "Elpida Creditor Installment Payments") in respect of the Elpida Companies' pre-petition creditors and their related claims. Substantially all of the $615 million we paid in connection with the acquisition of Elpida was deposited into accounts that are legally restricted for payment to the secured and unsecured creditors of Elpida in October 2013. The remaining 140 billion yen is due in six annual installments payable at the end of each calendar year beginning in 2014, with payments of 20 billion yen in each of 2014 through 2017, and payments of 30 billion yen in each of 2018 and 2019. Pursuant to the terms of the Sponsor Agreement, we entered into a series of agreements with the Elpida Companies, including supply agreements, research and development services agreements and general services agreements, which are intended to generate more stable operating cash flows to meet the requirements of the Elpida Companies' businesses, including the funding of the Elpida Creditor Installment Payments.
	The remaining 140 billion yen of installment payments are also to be deposited into accounts that are legally restricted for settlement of the Elpida Creditor Installment Payments and will be directed by the trustees of the Elpida Companies to the secured and unsecured creditors of the Elpida Companies. A portion of the amounts are also subject to adjustment for certain expenses of the reorganization proceedings and certain other items. Additionally, settlements of certain pre-petition intercompany obligations between Elpida, Akita and Rexchip are included in the amounts scheduled to be deposited into the restricted cash account, but are eliminated in consolidation and therefore are excluded from our consolidated obligation to the secured and unsecured creditors of the Elpida Group. Also, a portion of each installment amount payable to the creditors of the Elpida Companies will continue to be restricted by the trustees of the Elpida Companies in the event that any outstanding claims, which were not treated as fixed claims under the plans of reorganization at the time the plans were filed with the Japan Court, become fixed claims. These fixed claims will be paid under the plans of reorganization in the same manner as the fixed claims of other creditors. To the extent the aggregate amounts reserved from the installment payments exceed the aggregate amounts payable with respect to these unfixed claims once they become fixed, the excess amounts reserved will be distributed to unsecured creditors with respect to their fixed claims, resulting in an increased recovery for the unsecured creditors out of the installment payments. To the extent the aggregate amounts reserved are less than the aggregate amounts payable with respect to these unfixed claims once they become fixed, the Elpida Companies would be responsible to fund any shortfall to ensure that the creditors receive the minimum recovery to which they are entitled under the plans of reorganization with respect to these claims. As a result, there is a possibility that the total amount payable by the Elpida Companies to their creditors under the plans of reorganization will exceed 200 billion yen. In addition, certain of these unfixed claims may be resolved pursuant to settlement arrangements or other post-petition agreements and a substantial portion of the amounts payable under such agreements may have to be funded by the Elpida Companies outside of the plans of reorganization.
	The Elpida Creditor Installment Payments were recognized at the acquisition date fair value, which reflects the present value of the Elpida Creditor Installment Payments, discounted using a rate based on indices of leveraged loan markets, adjusted for security-specific risks of the installment payments. As of August 29, 2013, the discount is being accreted to interest expense over the remaining term of the Elpida Creditor Installment Payments, resulting in an effective interest rate of 6.25%.
	The following table presents the amounts scheduled under the Sponsor Agreement to be restricted for settlement of the Elpida Creditor Installment Payments, the estimated amounts payable to the secured and unsecured creditors of the Elpida Companies (stated in Japanese yen and U.S. dollars) and the amount of unamortized discount.

	Capital Lease Obligations
	We have various capital lease obligations due in periodic installments with a weighted-average remaining term of 4.0 years and weighted-average effective interest rates of 4.1% as of 2013 and 4.9% as of 2012. In 2013, we received $126 million in proceeds from equipment sale-leaseback transactions and as a result recorded capital lease obligations aggregating $126 million at a weighted-average effective interest rate of 4.3%, payable in periodic installments through July 2017. On July 31, 2013, in connection with our acquisition of the Elpida Companies and purchase of the Rexchip shares from Powerchip, we recorded $377 million of capital lease obligations at a weighted-average effective interest rate of 3.2%, payable in periodic installments with a weighted-average remaining term of 5.5 years. In 2012, we received $609 million in proceeds from equipment sale-leaseback transactions and as a result recorded capital lease obligations aggregating $609 million at a weighted-average effective interest rate of 4.2%, payable in periodic installments through August, 2016.
	Convertible Notes With Debt and Equity Components
	The 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 our nonconvertible borrowing rate when interest expense is recognized in subsequent periods. The amount recorded as debt is based on the fair value of the debt component as a standalone instrument, determined using an average interest rate for similar nonconvertible debt issued by entities with credit ratings comparable to ours at the time of issuance. The difference between the debt recorded at inception and its principal amount is to be accreted to principal through interest expense through the estimated life of the note.

2014 Notes
In May 2007, we issued $1.3 billion of aggregate principal amount of the 2014 Notes due June 2014, of which $464 million was repurchased on February 12, 2013 and $351 million was extinguished in 2011 in connection with debt restructures (see "Debt Restructure" below). The initial conversion rate of the 2014 Notes is 70.2679 shares of common stock per $1,000 principal amount, or approximately $14.23 per share. Interest is payable in June and December of each year.
Conversion Rights: Holders may convert their 2014 Notes under the following circumstances: (1) 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 immediately preceding calendar quarter is more than 130% of the conversion price of the 2014 Notes (approximately $18.50 per share); (2) if the 2014 Notes have been called for redemption; (3) if specified distributions or corporate events occur, as set forth in the indenture for the 2014 Notes; (4) if the trading price of the 2014 Notes is less than 98% of the product of the closing price of our common stock and the conversion rate of the 2014 Notes during the periods specified in the indenture; or (5) at any time on or after March 1, 2014.
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 2014 Notes in cash upon conversion. As a result, upon conversion of the 2014 Notes, only the amounts payable in excess of the principal amounts of the 2014 Notes are considered in diluted earnings per share under the treasury stock method.
Cash Redemption at Our Option: We may redeem for cash the 2014 Notes if the last reported sale price of our common stock has been at least 130% of the conversion price (approximately $18.50 per share) for at least 20 trading days during any 30 consecutive trading-day period. The redemption price is the principal amount to be redeemed, plus accrued and unpaid interest.
Cash Repurchase at the Option of the Holder: Upon a change in control or a termination of trading, as defined in the indenture, holders may require us to repurchase for cash all or a portion of their 2014 Notes at a repurchase price equal to the principal amount, plus accrued and unpaid interest, if any.
2027 Notes
In connection with a debt restructure in 2011 (see "Debt Restructure" below), we issued $175 million of the 2027 Notes due June 2027. The initial conversion rate is 91.7431 shares of common stock per $1,000 principal amount or approximately $10.90 per share, and is subject to adjustment upon the occurrence of certain events specified in the indenture.
Conversion Rights: Holders may convert their 2027 Notes under the following circumstances: (1) 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 immediately preceding calendar quarter is more than 130% of the conversion price (approximately $14.17 per share); (2) if the 2027 Notes have been called for redemption; (3) if specified distributions or corporate events occur; (4) if the trading price of the 2027 Notes is less than 98% of the product of the closing price of our common stock and the conversion rate of the 2027 Notes during the period specified in the indenture; (5) upon our election to terminate the conversion right of the 2027 Notes; or (6) after March 1, 2027.
Upon conversion, we will pay cash up to the aggregate principal amount and shares of common stock or cash, at our option, for any remaining conversion obligation. As a result of the conversion provisions in the indenture, upon conversion of the 2027 Notes, only the amounts payable in excess of the principal amounts of the 2027 Notes are considered in diluted earnings per share under the treasury stock method.
Cash Redemption at Our Option: We may redeem for cash the 2027 Notes on or after June 1, 2014 at a price equal to 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 2027 Notes to repurchase for cash the 2027 Notes on June 1, 2017. The repurchase price is 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, we may be required by the holders of the 2027 Notes to repurchase for cash all or a portion of their 2027 Notes at a repurchase price equal to the principal amount plus accrued and unpaid interest.
Termination of Conversion Rights: We may elect to terminate the conversion right of the 2027 Notes if the daily volume weighted average price of our common stock is greater than or equal to 130% of the conversion price (approximately $14.17 per share) for at least 20 trading days during any 30 consecutive trading day period. If we terminate the conversion right prior to June 1, 2014 and any 2027 Notes are converted in connection with the termination, we will pay a make-whole premium equal to the accrued interest as of the conversion date plus the present value of remaining interest that would have been paid through June 1, 2014, discounted using a U.S. Treasury bond with an equivalent term. Subject to the terms of the indenture, we may, at our election, deliver shares of common stock in lieu of cash with respect to this make-whole payment.
2031A and 2031B Notes
On July 26, 2011, we issued $345 million of the 2031A Notes and $345 million of 2031B Notes (collectively referred to as the "2031 Notes"), each due August 2031. The initial conversion rate for the 2031 Notes is 105.2632 shares of common stock per $1,000 principal amount, equivalent to an initial conversion price of approximately $9.50 per share of common stock. Interest is payable in February and August of each year.

Upon conversion, we will pay cash up to the lesser of the aggregate principal amount and the conversion value and cash, shares of common stock or a combination of cash and shares of common stock, at our option, for any remaining conversion obligations. As a result of the conversion provisions in the indenture, upon conversion of the 2031 Notes, only the amounts payable in excess of the principal amounts of the 2031 Notes are considered in diluted earnings per share under the treasury stock method.
Cash Redemption at Our Option: We may redeem for cash the 2031A Notes on or after August 5, 2013 and the 2031B Notes on or after August 5, 2014 if the last reported sale price of our common stock has been at least 130% of the conversion price (approximately $12.35 per share) 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 2031A Notes prior to August 5, 2015, or the 2031B Notes prior to August 5, 2016, we will also pay a make-whole premium in cash equal to the present value of all remaining scheduled payments of interest on the 2031 Notes from the redemption date to August 5, 2015 for the 2031A Notes and through August 5, 2016 for the 2031B Notes, using a discount rate equal to 150 basis points.
Cash Repurchase at the Option of the Holder: We may be required by the holders of the 2031 Notes to repurchase for cash all or a portion of the 2031A Notes on August 1, 2018 and all or a portion of the 2031B Notes on August 1, 2020. The repurchase price is 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, we may be required by the holders of the 2031 Notes to repurchase for cash all or a portion of their 2031 Notes at a repurchase price equal to the principal amount plus accrued and unpaid interest.
2032C and 2032D Notes
On April 18, 2012, we issued $550 million of the 2032C Notes and $450 million of the 2032D Notes (collectively referred to as the "2032 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.
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 (approximately $12.52 per share for the 2032C Notes and $12.97 per share for the 2032D Notes) of the 2032C or 2032D Notes; (3) if the trading price of the 2032C or 2032D Notes is less than 98% of the product of the closing price of our common stock and the conversion rate of the 2032C or 2032D 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 conversion. As a result, upon conversion of the 2032 Notes, only the amounts payable in excess of the principal amounts 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 (approximately $12.52 per share for the 2032C Notes and $12.97 per share for the 2032D Notes) 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.

The repurchase price is 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 repurchase price equal to the principal amount plus accrued and unpaid interest.
2033E and 2033F Notes

Issuance costs for the 2033 Notes totaled $16 million. 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.
Upon issuance of the 2033 Notes, we recorded $526 million of debt, $72 million of additional capital and $14 million of deferred debt issuance costs (included in other noncurrent assets). The amount recorded as debt was based on the fair value of the debt component as a standalone instrument and was determined using an average interest rate for similar nonconvertible debt issued by entities with credit ratings comparable to ours at the time of issuance (Level 2 fair value measurements). The difference between the debt recorded at inception and the principal amount ($31 million for the 2033E Notes and $43 million for the 2033F Notes) is being accreted to principal as interest expense through February 2018 for the 2033E Notes and February 2020 for the 2033F Notes, the expected life of the notes.
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 (approximately $14.21 per share) of the 2033 Notes; (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, upon conversion of the 2033 Notes, only the amounts payable in excess of the principal amounts 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. The redemption price will 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. The repurchase price is 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 repurchase price equal to the principal amount plus accrued and unpaid interest.
Other Notes Payable
On August 27, 2013, we borrowed $312 million under a four-year term loan, collateralized by a security interest in certain production equipment. Principal is payable in equal quarterly installments, commencing on November 27, 2013. Interest accrues at a variable rate equal to the three-month London Interbank Offered Rate (“LIBOR”) rate plus a margin of 3.25% per annum, payable quarterly in arrears. Also on August 27, 2013, we entered into a variable-for-fixed interest rate swap calculated on an aggregate notional amount equal to the scheduled outstanding balance of the loan. The interest rate swap effectively fixed the rate at 4.2% per annum. The facility agreement contains customary covenants, limitations or restrictions our ability to create liens or dispose of the equipment securing the facility agreement. The facility also contains a covenant requiring us to ensure that the ratio of the outstanding loan to the fair market value of the equipment that secures the loan does not exceed 0.8 to 1.0. If such ratio is exceeded, we are required to grant a charge over additional equipment and/or prepay the loan in an amount sufficient to reduce such ratio to 0.8 to 1.0 or less. The facility agreement also contains customary events of default which could result in the acceleration of all amounts and cancellation of all commitments under the facility agreement. As of August 29, 2013, the outstanding balance was $309 million.
On October 2, 2012, we entered into a facility agreement to obtain financing collateralized by semiconductor production equipment.  Subject to customary conditions, we could draw up to $214 million under the facility agreement.  Amounts drawn are payable in 10 equal semi-annual installments beginning six months after the draw date.  On October 18, 2012, we drew $173 million with interest at 2.4% per annum.  On January 31, 2013, we drew the remaining $41 million with interest at 2.4% per annum. The facility agreement contains customary covenants and events of default. As of August 29, 2013, the outstanding balance was $191 million.
On July 31, 2013, in connection with our acquisition of the Elpida Companies and purchase of the Rexchip shares from Powerchip, we recorded a note payable of $120 million, which is collateralized by building and certain production equipment.  The note is denominated in New Taiwan dollars. Principal on the note is payable in equal quarterly installments through May 2016 and accrued interest is payable monthly. Interest accrues at a variable rate of 0.85% above the secondary market rate for 90-day New Taiwan dollar commercial paper, subject to a minimum interest rate of 2.50% per annum. As of August 29, 2013, the outstanding balance was $110 million.
In connection with the IM Flash joint venture agreements, on April 6, 2012, we borrowed $65 million under a two-year senior unsecured promissory note from Intel, payable in approximately equal quarterly installments with interest at a rate of three-month LIBOR minus 50 basis points. The proceeds of the loan are to be used to fund purchases of equipment relating to the research and development or manufacturing of certain emerging memory technologies. As of August 29, 2013, the outstanding balance was $25 million. (See "Consolidated Variable Interest Entities – IM Flash" note.)
Revolving Credit Facilities
On September 5, 2012, we entered into a three-year revolving credit facility. Under this credit facility, we can draw up to the lesser of $255 million or 80% of the net outstanding balance of certain trade receivables. Amounts drawn would be collateralized by a security interest in such receivables. The availability of the facility is subject to certain customary conditions, including the absence of any event or circumstance that has a material adverse effect on our business or financial condition. The revolving credit facility contains customary covenants and a repayment provision in the event that the maximum aging of the receivables exceeds a specified threshold. Interest is payable monthly on any outstanding principal balance at a variable rate equal to the 30-day Singapore Interbank Offering Rate plus 2.8% per annum. As of August 29, 2013, we had not drawn any of the $255 million available under this facility.
On June 27, 2013, we entered into a senior secured three-year revolving credit facility, collateralized by a security interest in certain trade receivables. Under this facility, we can draw up to 85% of the net outstanding balance of certain trade receivables, subject to certain adjustments, including an availability block that has the effect of limiting the maximum committed draw amount to approximately $153 million. The revolving 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 our business or financial condition.  Generally, interest is payable on any outstanding principal balance at a variable rate equal to the LIBOR plus a spread from 1.5% to 2.0%, or at our option, at a rate equal to an alternate base rate (defined as the highest of (1) the prime rate, (2) one-month LIBOR plus 1.0% or (3) the Federal Funds Effective Rate) plus a spread from 0.5% to 1.0%.  In either case, the spread added to the applicable interest rate basis varies depending upon the amount of the monthly average undrawn availability under the facility. As of August 29, 2013, we had not drawn any of the $153 million available under this facility.
2013 Notes Conversion
In 2012, we provided a written notice that we would redeem our 2013 convertible senior notes on June 4, 2012. As of June 4, 2012, the entire $139 million of principal amount of the 2013 Notes had been converted by holders into 27.3 million shares. We were required to pay a make-whole premium of $9 million, which is reflected in interest expense.
Debt Restructure
On February 12, 2013, we repurchased $464 million of aggregate principal amount of our 2014 Notes for $477 million in privately negotiated transactions. The liability and equity components of the 2014 Notes were stated separately pursuant to the accounting standards for convertible debt instruments that may be fully or partially settled in cash upon conversion. Accordingly, the repurchase resulted in the derecognition of $431 million in debt for the principal amount (net of $33 million of debt discount) and $15 million in additional capital for the equity component. We recognized a charge of $31 million associated with the early repurchase, based on the estimated $462 million fair value of the debt component and the $431 million carrying value (net of unamortized discount) of the notes repurchased. The fair value of the debt component was estimated using an interest rate for non-convertible debt, with terms similar to the debt component of the 2014 Notes on a stand-alone basis issued by entities with credit ratings similar to ours at the repurchase date (Level 2 fair value measurements).
In the first quarter of 2011, in connection with a series of debt restructure transactions with certain holders of our convertible notes, we recognized a loss of $111 million as follows:
•	$15 million on the exchange of $175 million in aggregate principal amount of our 2014 Notes for $175 million in aggregate principal amount of new 2027 Notes;
•	$17 million (including transaction fees) on the repurchase of $176 million in aggregate principal amount of our 2014 Notes for $171 million in cash; and
•	$79 million (including transaction fees) on the repurchase of $91 million in aggregate principal amount of our 2013 Notes for $166 million in cash.
Maturities of Notes Payable and Future Minimum Lease Payments
As of August 29, 2013, maturities of notes payable, including the Elpida Creditor Installment Payments, and future minimum lease payments under capital lease obligations were as follows:

	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 balance sheet date, 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.
	We are engaged in litigation with Rambus, Inc. ("Rambus") relating to certain of Rambus' patents and certain of our claims and defenses. Our lawsuits with Rambus related to patent matters are pending in the U.S. District Court for the District of Delaware, U.S. District Court for the Northern District of California, Germany, France, and Italy. On August 28, 2000, we filed a complaint against Rambus in the U.S. District Court for the District of Delaware seeking declaratory and injunctive relief. The complaint alleges, among other things, various anticompetitive activities and also seeks a declaratory judgment that certain Rambus patents are invalid and/or unenforceable. Rambus subsequently filed an answer and counterclaim in Delaware alleging, among other things, infringement of twelve Rambus patents and seeking monetary damages and injunctive relief. We subsequently added claims and defenses based on Rambus' alleged spoliation of evidence and litigation misconduct. The spoliation and litigation misconduct claims and defenses were heard in a bench trial before Judge Robinson in October 2007. On January 9, 2009, Judge Robinson entered an opinion in our favor holding that Rambus had engaged in spoliation and that the twelve Rambus patents in the suit were unenforceable against us. Rambus subsequently appealed the decision to the U.S. Court of Appeals for the Federal Circuit. On May 13, 2011, the Federal Circuit affirmed Judge Robinson's finding of spoliation, but vacated the dismissal sanction and remanded the case to the Delaware District Court for analysis of the remedy based on the Federal Circuit's decision. On January 2, 2013, Judge Robinson entered a new opinion in our favor holding that Rambus had engaged in spoliation, that Rambus' spoliation was done in bad faith, that the spoliation prejudiced us, and that the appropriate sanction was to declare the twelve Rambus patents in the suit unenforceable against us.  On March 27, 2013, Rambus filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit. Separately, on January 13, 2006, Rambus filed a lawsuit against us in the U.S. District Court for the Northern District of California alleging that certain of our DDR2, DDR3, RLDRAM and RLDRAM II products infringe as many as fourteen Rambus patents and seeking monetary damages, treble damages, and injunctive relief. The Northern District of California Court stayed the trial of the patent phase of the Northern District of California case upon appeal of the Delaware spoliation issue to the Federal Circuit.
	On September 1, 2011, HSM Portfolio LLC and Technology Properties Limited LLC filed a patent infringement action in the U.S. District Court for the District of Delaware against us and seventeen other defendants, including Elpida Memory, Inc. and Elpida Memory (USA) Inc. (collectively "Elpida"). The complaint alleges that certain of our DRAM and image sensor products infringe two U.S. patents and that certain Elpida DRAM products infringe two U.S. patents and seeks damages, attorneys' fees, and costs. On March 23, 2012, Elpida filed a Notice of Filing and Hearing on Petition Under Chapter 15 of the U.S. Bankruptcy Code and Issuance of Provisional Relief that included an order of the U.S. Bankruptcy Court for the District of Delaware staying judicial proceedings against Elpida. Accordingly, the plaintiffs' case against Elpida is stayed. On August 21, 2013, the Court granted a motion by the plaintiffs to amend the complaint to assert two additional patents against us and one additional patent against Elpida.
	On September 9, 2011, Advanced Data Access LLC filed a patent infringement action in the U.S. District Court for the Eastern District of Texas (Tyler) against us and seven other defendants. On November 16, 2011, Advanced Data Access filed an amended complaint. The amended complaint alleged that certain of our DRAM products infringed two U.S. patents and sought injunctive relief, damages, attorneys' fees, and costs. On March 20, 2013, we executed a settlement agreement resolving this litigation. The settlement amount did not have a material effect on our business, results of operations or financial condition.
	On September 14, 2011, Smart Memory Solutions LLC filed a patent infringement action in the U.S. District Court for the District of Delaware against us and Winbond Electronics Corporation of America.  The complaint alleged that certain of our NOR Flash products infringed a single U.S. patent and sought injunctive relief, damages, attorneys' fees, and costs. On March 20, 2013, we executed a settlement agreement resolving this litigation. The settlement amount did not have a material effect on our business, results of operations or financial condition.
	On December 5, 2011, the Board of Trustees for the University of Illinois filed a patent infringement action against us in the U.S. District Court for the Central District of Illinois. The complaint alleges that unspecified semiconductor products of ours infringe three U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. We have filed three petitions for inter-partes review by the Patent and Trademark Office, challenging the validity of each of the patents in suit. The District Court has stayed the litigation pending the outcome of the inter-partes review by the Patent Office.
	On March 26, 2012, Semiconductor Technologies, LLC filed a patent infringement action in the U.S. District Court for the Eastern District of Texas (Marshall) against us. The complaint alleged that certain of our DRAM products infringed five U.S. patents and sought injunctive relief, damages, attorneys' fees, and costs. On March 20, 2013, we executed a settlement agreement resolving this litigation. The settlement amount did not have a material effect on our business, results of operations or financial condition.
	On April 27, 2012, Semcon Tech, LLC filed a patent infringement action against us in the U.S. District Court for the District of Delaware. The complaint alleges that our use of various chemical mechanical planarization systems purchased from Applied Materials and others infringes a single U.S. patent and seeks injunctive relief, damages, attorneys' fees, and costs. On September 24, 2013, the Court entered an order staying our case pending the resolution of co-pending cases brought by Semcon Tech, LLC against Applied Materials and Ebara Technologies, Inc.
	On December 7, 2007, Tessera, Inc. filed a patent infringement against Elpida Memory, Inc., Elpida Memory (USA) Inc. (collectively "Elpida"), and numerous other defendants, in the United States District Court for the Eastern District of Texas. The complaint alleges that certain Elpida products infringe four U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. Prior to answering the complaint, Elpida and other defendants filed motions to stay the case pending final resolution of a case before the International Trade Commission ("ITC") against Elpida and other respondents, alleging infringement of the same patents asserted in the Eastern District of Texas case (In The Matter of Certain Semiconductor Chips with Minimized Chip Package Size and Products Containing Same (III), ITC No. 337-TA-630 (the "ITC Action")). On February 25, 2008, the Eastern District of Texas Court granted the defendants' motion to stay the action. On December 29, 2009, the ITC issued a Notice of Final Determination in the ITC Action finding no violation by Elpida. Tessera Inc. subsequently appealed the matter to the U.S. Court of Appeals for the Federal Circuit. On May 23, 2011, the Federal Circuit affirmed the ITC's Final Determination. The Eastern District of Texas case currently remains stayed.
	Among other things, the above lawsuits pertain to certain of our SDRAM, DDR, DDR2, DDR3, RLDRAM, NAND Flash, NOR Flash and image sensor products, 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, except as noted in the discussion of the Advanced Data Access LLC, Smart Memory Solutions LLC and Semiconductor Technologies, LLC matters above. A court determination that our products or manufacturing processes infringe the intellectual property rights of others 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.
	Antitrust Matters
	On May 5, 2004, Rambus filed a complaint in the Superior Court of the State of California (San Francisco County) against us and other DRAM suppliers which alleged that the defendants harmed Rambus by engaging in concerted and unlawful efforts affecting Rambus DRAM by eliminating competition and stifling innovation in the market for computer memory technology and computer memory chips.  Rambus' complaint alleged various causes of action under California state law including, among other things, a conspiracy to restrict output and fix prices, a conspiracy to monopolize, intentional interference with prospective economic advantage, and unfair competition. Rambus sought a judgment for damages of approximately $3.9 billion, joint and several liability, trebling of damages awarded, punitive damages, a permanent injunction enjoining the defendants from the conduct alleged in the complaint, interest, and attorneys' fees and costs. Trial began on June 20, 2011, and the case went to the jury on September 21, 2011. On November 16, 2011, the jury found for us on all claims. On April 2, 2012, Rambus filed a notice of appeal to the California 1st District Court of Appeal.
	At least sixty-eight purported class action price-fixing lawsuits have been filed against us and other DRAM suppliers in various federal and state courts in the United States and in Puerto Rico on behalf of indirect purchasers alleging a conspiracy to increase DRAM prices in violation of federal and state antitrust laws and state unfair competition law, and/or unjust enrichment relating to the sale and pricing of DRAM products during the period from April 1999 through at least June 2002. The complaints seek joint and several damages, trebled, in addition to restitution, costs and attorneys' fees. A number of these cases were removed to federal court and transferred to the U.S. District Court for the Northern District of California for consolidated pre-trial proceedings. In July, 2006, the Attorneys General for approximately forty U.S. states and territories filed suit in the U.S. District Court for the Northern District of California. The complaints allege, among other things, violations of the Sherman Act, Cartwright Act, and certain other states' consumer protection and antitrust laws and seek joint and several damages, trebled, as well as injunctive and other relief. On October 3, 2008, the California Attorney General filed a similar lawsuit in California Superior Court, purportedly on behalf of local California government entities, alleging, among other things, violations of the Cartwright Act and state unfair competition law. On June 23, 2010, we executed a settlement agreement resolving these purported class-action indirect purchaser cases and the pending cases of the Attorneys General relating to alleged DRAM price-fixing in the United States. Subject to certain conditions, including final court approval of the class settlements, we agreed to pay approximately $67 million in aggregate in three equal installments over a two-year period. We had paid the full amount into an escrow account by the end of the first quarter of 2013 in accordance with the settlement agreement.
	Three putative class action lawsuits alleging price-fixing of DRAM products also have been filed against us in Quebec, Ontario, and British Columbia, Canada, on behalf of direct and indirect purchasers, asserting violations of the Canadian Competition Act and other common law claims (collectively the "Canadian Cases").  The claims were initiated between December 2004 (British Columbia) and June 2006 (Quebec). The plaintiffs seek monetary damages, restitution, costs, and attorneys' fees. The substantive allegations in these cases are similar to those asserted in the DRAM antitrust cases filed in the United States.  Plaintiffs' motion for class certification was denied in the British Columbia and Quebec cases in May and June 2008, respectively.  Plaintiffs subsequently filed an appeal of each of those decisions.  On November 12, 2009, the British Columbia Court of Appeal reversed, and on November 16, 2011, the Quebec Court of Appeal also reversed the denial of class certification and remanded the cases for further proceedings. On October 16, 2012, we entered into a settlement agreement resolving these three putative class action cases subject to certain conditions including final court approval of the settlement. The settlement amount did not have a material effect on our business, results of operations or financial condition.
	On June 21, 2010, the Brazil Secretariat of Economic Law of the Ministry of Justice ("SDE") announced that it had initiated an investigation relating to alleged anticompetitive activities within the DRAM industry. The SDE's Notice of Investigation names various DRAM manufacturers and certain executives, including us, and focuses on the period from July 1998 to June 2002.
	We are unable to predict the outcome of these matters and therefore cannot estimate the range of possible loss, except as noted in the U.S. indirect purchaser cases and the Canadian Cases above. The final resolution of these alleged violations of antitrust laws could result in significant liability and could have a material adverse effect on our business, results of operations or financial condition.
	Securities Matters
	On July 12, 2013, seven former shareholders of Elpida Memory, Inc. (“Elpida”) filed a complaint against Messrs. Sakamoto, Adachi, Gomi, Shirai, Tsay-Jiu, Wataki, Kinoshita, and Takahasi in their capacity as members of the board of directors of Elpida as of February 2013. The complaint alleges that the defendants engaged in various acts and misrepresentations to hide the financial condition of Elpida and deceive shareholders prior to Elpida filing a petition for corporate reorganization on February 27, 2013. The plaintiffs seek joint and several damages equal to the market value of shares owned by each of the plaintiffs on February 23, 2013, along with attorneys’ fees and interest. At a hearing on September 25, 2013, the plaintiffs withdrew the complaint against Mr. Tsay-Jiu.
	We are unable to predict the outcome of this matter and therefore cannot estimate the range of possible loss.  The final resolution of this matter could result in significant liability and could have a material adverse effect on our business, results of operations or financial condition.
	Commercial Matters
	On January 20, 2011, Dr. Michael Jaffé, administrator for Qimonda AG ("Qimonda") insolvency proceedings, filed suit against us and Micron Semiconductor B.V., our Netherlands subsidiary, 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 us and Qimonda signed in fall 2008 pursuant to which we purchased all of Qimonda's shares of Inotera Memories, Inc. and seeks an order requiring us to retransfer the Inotera shares purchased from Qimonda to the Qimonda estate. The complaint also seeks 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. A three-judge panel will render a decision after a series of hearings with pleadings, arguments and witnesses. Hearings were held on September 25, 2012, February 5, 2013, June 11, 2013 and July 2, 2013. An additional hearing is scheduled for November 12, 2013. We are unable to predict the outcome of this lawsuit 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 equivalent monetary damages and 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 August 29, 2013, the Inotera shares purchased from Qimonda had a carrying value of $190 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.

	Capped Calls
	Issued and Outstanding Capped Calls: In July 2011, we entered into capped call transactions (the "2031 Capped Calls") that have an initial strike price which was set to equal, subject to certain adjustments, the initial conversion price of the 2031 Notes. The 2031 Capped Calls are in four equal tranches. In April 2012, we entered into capped call transactions (the "2032C Capped Calls" and "2032D Capped Calls," collectively the "2032 Capped Calls") that have an initial strike price which was set to be, subject to certain adjustments, slightly higher than the initial conversion prices of the 2032C Notes and the 2032D Notes.  The 2032C and 2032D Capped Calls are each in four tranches. On February 6, 2013 and February 12, 2013, we entered into capped call transactions (the "2033E Capped Calls" and "2033F Capped Calls," collectively the "2033 Capped Calls") that have an initial strike price which was set to equal, subject to certain adjustments, the initial conversion price of the 2033 Notes.  We paid $57 million, $103 million and $48 million, to purchase the 2031, 2032 and 2033 Capped Calls, respectively. The capped calls transactions are considered capital transactions and the related cost was recorded as a charge to additional capital. The 2031, 2032 and 2033 Capped Calls are intended to reduce the effect of potential dilution upon conversion of the 2031, 2032 and 2033 Notes, respectively and may be settled in shares or cash, at our election.

If share settlement were elected, the number of shares repurchased 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 Capped Calls: Concurrent with the issuance in April 2009 of our 4.25% Convertible Senior Notes due 2013, we entered into capped call transactions (the "2013 Capped Calls") covering approximately 45.2 million shares of common stock with an initial strike price of approximately $5.08 per share and a cap price of $6.64 per share.  The 2013 Capped Calls expired in October 2012 and November 2012.  We elected cash settlement and received $24 million in 2013.
	Concurrent with the offering of the 2014 Notes, we purchased capped calls with a strike price of approximately $14.23 per share and various expiration dates between November 2011 and December 2012 (the "2014 Capped Calls").  In the first six months of 2012, 2014 Capped Calls covering 30.4 million shares expired according to their terms.  In April 2012, we settled the remaining 2014 Capped Calls, covering 60.9 million shares, and received a de minimis payment.

Derivative Financial Instruments	Derivative Financial Instruments
	We are exposed to currency exchange rate risk for monetary assets and liabilities held or denominated in foreign currencies, primarily the euro, shekel, Singapore dollar and yen.  We are also exposed to currency exchange rate risk for capital expenditures and operating cash flows, primarily denominated in the euro and yen.  In connection with the Elpida Installment Payments, we are exposed to significant currency exchange rate risk for the yen. Additionally, we are exposed to interest rate fluctuation risk on our four-year note payable, under which we borrowed $312 million on August 27, 2013 at a variable interest rate. We use derivative instruments to manage a portion of our exposures to changes in currency exchange rates and variable interest rates.  For exposures associated with our monetary assets and liabilities, our primary objective in entering into currency derivatives is to reduce the volatility that changes in currency exchange rates have on our earnings.  For exposures associated with our capital expenditures and operating cash flows, our primary objective of entering into currency derivatives is to reduce the volatility that changes in currency exchange rates have on future cash flows. For exposures associated with our yen-denominated Elpida Installment Payments, our primary objective for entering into currency derivatives is to mitigate risks if those currencies strengthen relative to the U.S. dollar, while preserving some ability for us to benefit if those currencies weaken. For exposures associated with our variable-rate debt, our primary objective is to reduce the volatility that changes in interest rates have on interest expense.
	Our currency derivatives consist primarily of forward contracts and currency options and our interest rate derivative consists of interest rate swap agreements.  These derivatives expose us to credit risk to the extent the counterparties may be unable to meet the terms of the derivative instrument.  As of August 29, 2013, our maximum exposure to loss due to credit risk if counterparties fail completely to perform according to the terms of the contracts, was generally equal to the fair value of our assets for these contracts as listed in the tables below.  We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading risk across multiple major financial institutions.  In addition, we monitor the potential risk of loss with any one counterparty resulting from this type of credit risk on an ongoing basis.  We also seek to mitigate risk through master netting arrangements (see "Master Netting Arrangements" below).
	We have the following risk management programs:
	Derivatives without Hedge Accounting Designation
	We utilize a rolling hedge strategy with currency forward contracts that generally mature within 35 days to hedge our exposure to changes in currency exchange rates from our monetary assets and liabilities.  At the end of each reporting period, monetary assets and liabilities held or 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). Currency options are valued at their fair value using a modified Black-Scholes option valuation model using inputs of the current spot rate, strike price, risk-free interest rate, maturity, volatility and credit-risk spread (Level 2 fair value measurements).  These options are marked-to-market at the end of each reporting period. Realized and unrealized gains and losses on derivative instruments 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).
	In connection with the currency exchange rate risk associated with our acquisition of Elpida and the Rexchip shares from the Powerchip Group, we entered into currency exchange transactions (the "Elpida Hedges" and the "Rexchip Hedges" and, together, the "Elpida Acquisition Hedges"). The Elpida Acquisition Hedges were not designated for hedge accounting and were remeasured at fair value each period with gains and losses reflected in other non-operating income (expense). We recorded losses from the Elpida Acquisition Hedges in 2013 of $228 million and gains in 2012 of $8 million. To mitigate the risk that increases in exchange rates have on the payments due in 2014 and 2015, we entered into forward contracts to purchase 20 billion yen on November 28, 2014 and 10 billion yen on November 27, 2015.
	We entered into interest rate swap contracts that mature in 4 years to hedge against the variability of future interest payments due on our $312 million floating rate debt. We designated 80% of the swaps as cash flow hedges and the remaining 20% were not designated for hedge accounting treatment. Changes in the fair value of the undesignated portion are included in interest income (expense). The fair values of the interest rate swaps are calculated by discounting the expected future cash flows based on inputs that are readily available in publicly quoted markets (Level 2 fair value measurements).
	Total gross notional amounts and fair values for currency derivatives and interest rate swaps without hedge accounting designation were as follows:
			Notional Amount					Fair Value of

	Derivatives with Cash Flow Hedge Accounting Designation
	We utilize currency forward contracts that generally mature within 12 months and currency options that generally mature from 12 to 18 months to hedge our exposure to changes in cash flows from changes in currency exchange rates for certain capital expenditures and forecasted operating cash flows.  Currency forward contracts are valued at their fair values based on market-based observable inputs including currency exchange spot and forward rates, interest rate and credit risk spread (Level 2 fair value measurements).  Currency options are valued at their fair value using a modified Black-Scholes option valuation model using inputs of the current spot rate, strike price, risk-free interest rate, maturity, volatility and credit-risk spread (Level 2 fair value measurements). We entered into interest rate swap contracts that mature in 4 years to hedge against the variability in future interest payments due on our $312 million floating rate debt and designated 80% of the swaps as cash flow hedges. The fair values of the interest rate swaps have been calculated by discounting the expected future cash flows based on inputs that are readily available in publicly quoted markets (Level 2 fair value measurements).
	For derivatives 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).  For derivatives hedging capital expenditures, the amounts in accumulated other comprehensive income (loss) for 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. Amounts in accumulated other comprehensive income (loss) for inventory purchases are reclassified to earnings when inventory is sold. Amounts in accumulated other comprehensive income (loss) for interest rate swaps are reclassified to earnings when the related interest payments affect earnings. The ineffective or excluded portion of the realized and unrealized gain or loss is included in other non-operating income (expense).  Total gross notional amounts and fair values for derivatives with cash flow hedge accounting designation were as follows:
			Notional Amount				Fair Value of

	For 2013, 2012 and 2011, we recognized $8 million of net pre-tax derivative losses, $9 million of net derivative losses and $49 million of net derivative gains, 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 2013, 2012 or 2011.  In 2013 and 2012, $1 million and $9 million, respectively, of net gains were reclassified from accumulated other comprehensive income (loss) to earnings. As of August 29, 2013, the amount of pre-tax net derivative gains included in accumulated other accumulated comprehensive income (loss) expected to be reclassified into earnings in the next 12 months was $4 million.
	Master Netting Arrangements
	We seek to enter into master netting arrangements to mitigate credit risk in derivative 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 under these arrangements have been presented in our consolidated balance sheet on a net basis. The following table presents the gross amounts of our derivative assets and liabilities and the net amounts recorded in our consolidated balance sheet:

	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).
	Fair Value Measurements on a Recurring Basis

	Government securities consist of securities issued directly by or deemed to be guaranteed by government entities such as U.S and non U.S. agency securities, government bonds and treasury securities. Level 2 securities are valued 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 our pricing services. As of August 29, 2013, no adjustments were made to such pricing information.
	Fair Value Measurements on a Nonrecurring Basis
	Our non-marketable securities, equity method investments, and non-financial assets such as intellectual property and property, plant and equipment are carried at cost unless impairment is deemed to have occurred.
	During the third quarter of 2012, the Board of Directors of Transform approved a liquidation plan. As a result, we impaired our investment in Transform to the estimated liquidation values for its assets and liabilities measured using unobservable inputs (Level 3). Transform's primary assets were semiconductor equipment and a manufacturing facility. The fair values for semiconductor equipment were based on quotations obtained from equipment dealers, which consider the remaining useful life and configuration of the equipment. Fair value for the facility was determined based on sales of similar facilities and properties in comparable markets. Based on our valuation of Transform's net assets, we recognized an other-than-temporary impairment charge of $69 million in equity in net income (losses) of equity method investees.
	Fair Value of Financial Instruments
	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 components of our convertible notes classified in equity) were as follows:
	As of	2013				2012
		Fair		Carrying		Fair		Carrying
		Value		Value		Value		Value

	Elpida creditor installment payments and other notes	2,269		2,279		56		58
	The fair values of our convertible debt instruments were determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including 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 are observable in the market or that could be derived from, or corroborated with, observable market data, including interest rates based on similar debt issued by parties with credit ratings similar to ours (Level 2).

	As of August 29, 2013, we had an aggregate of 160.2 million shares of common stock reserved for the issuance of stock options and restricted stock awards, of which 83.8 million shares were subject to outstanding awards and 76.4 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 September 2004 generally expire six years from the date of grant. All other options expire ten years from the grant date.
	Option activity for 2013 is summarized as follows:

	The weighted-average grant-date fair value per share was $3.34, $3.18 and $4.46 for options granted during 2013, 2012 and 2011, respectively. The total intrinsic value was $103 million, $6 million, and $35 million for options exercised during 2013, 2012 and 2011, respectively.
	The fair values of option awards were estimated at each grant date using the Black-Scholes option valuation model.  The Black-Scholes model requires the input of assumptions, including the expected stock-price volatility and estimated option life.  The expected volatilities utilized were based on implied volatilities from traded options on our stock and on 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.  Assumptions used in the Black-Scholes model are presented below:
	For the year ended	2013		2012			2011
	Average expected life in years	5.1		5.1			5.1
	Weighted-average expected volatility	59	%	66	%		56	%

	Restricted Stock and Restricted Stock Units ("Restricted Stock Awards")
	As of August 29, 2013, there were 13.0 million shares of Restricted Stock Awards outstanding, of which 3.4 million were performance-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.  For performance-based Restricted Stock Awards, vesting is contingent upon meeting certain performance goals.  Restricted Stock Awards activity for 2013 is summarized as follows:
		Number of Shares		Weighted-Average Grant Date Fair Value Per Share

	Stock-based compensation expense of $6 million and $5 million was capitalized and remained in inventory as of August 29, 2013 and August 30, 2012, respectively. As of August 29, 2013, $136 million of total unrecognized compensation costs, net of estimated forfeitures, related to non-vested awards was expected to be recognized through the fourth quarter of 2017, resulting in a weighted-average period of 1.2 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.  (See "Income Taxes" note.)

For 2013, restructure and asset impairment charges of $12 million, $11 million, $11 million and $6 million were recorded by our ESG, WSG, NSG and DSG operating segments. For 2012, restructure and asset impairment charges of $6 million and $3 million were recorded by our WSG and ESG operating segments and a gain of $1 million was recorded by our NSG operating segment. For 2011, restructure and asset impairment charges of $23 million, $21 million, $21 million and $4 million were recorded by our DSG, NSG, WSG and ESG operating segments. Our other segments that do not meet the quantitative thresholds of a reportable segment are reported under All Other and recorded the remaining restructure and asset impairment charges. (See "Segments" note.) As of August 29, 2013, we had accrued $12 million for unpaid other restructure activities related to our workforce optimization activity. As of August 29, 2013, we do not anticipate incurring any significant additional costs for these restructure activities.
	Micron Technology Italia, S.r.l. ("MIT")
	On May 3, 2013, we sold MIT, a wholly-owned subsidiary, including its 200mm wafer fabrication facility assets in Avezzano, Italy, to LFoundry. In exchange for the shares of MIT, we received consideration from LFoundry valued at $35 million, substantially all of which was under a 7-year, non-interest bearing term note. Under the terms of the agreements, we assigned to LFoundry our supply agreement with Aptina for CMOS image sensors manufactured at the Avezzano facility.
	The assets and liabilities of MIT, and related imager inventories, were classified as held for sale in 2013 and we recorded an impairment loss of $62 million to write down the assets and liabilities to their estimated fair values. The fair values were determined primarily based on the estimated fair value of proceeds from the sale to LFoundry (Level 3 fair value measurement). The carrying values of the MIT assets and liabilities sold, after the effects of the write down, were as follows:
	Other current assets	$	75
	Other noncurrent assets	37
	Accounts payable and accrued expenses	(43		)
	Other noncurrent liabilities	(34		)
		$	35
	Light-emitting Diode ("LED")
	In 2013, we discontinued the development activities of our LED operations. In connection therewith, we recognized a charge of $33 million primarily to write down certain production assets used in the development of LED technology to the expected proceeds from their sale. Fair value for these assets was based on quotations obtained from equipment dealers, which consider the remaining useful life and configuration of the equipment (Level 3 fair value measurement).
	STMicroelectronics S.r.l. ("ST") Consortium Agreement
	In 2013, we restructured a consortium agreement with ST whereby certain assets and approximately 500 employees from our Agrate, Italy fabrication facility were transferred to ST. The consortium agreement supports the R&D activities of us and ST and the manufacturing of semi-finished and advanced commercial semiconductor devices. In connection therewith, we recognized a restructure charge of $26 million for 2013, primarily from transfers of equipment.
	Lease to Transform
	In May 2012, the Board of Directors of Transform approved a liquidation plan. In connection therewith, Transform terminated a lease to a portion of our manufacturing facilities in Boise, Idaho and we recognized a gain of $25 million in 2013.
	Japan Fabrication Facility
	On June 2, 2011, we sold our wafer fabrication facility in Japan (the "Japan Fab") to Tower Semiconductor Ltd. ("Tower"). Under the arrangement, Tower paid $40 million in cash, approximately 1.3 million ordinary shares of Tower (subsequent to a 1 for 15 reverse stock split on August 6, 2012), and $20 million in installment payments, which we received in 2012. The net carrying value of assets sold and liabilities transferred to Tower on the transaction date prior to the effects of the transaction was $23 million and we recorded a gain of $54 million (net of transaction costs of $3 million) in connection with the sale of the Japan Fab. We also recorded a tax provision of $74 million related to the gain on the sale and to write down certain deferred tax assets associated with the Japan Fab. In connection with the sale of the Japan Fab, we entered into a supply agreement for Tower to manufacture products for us in the facility through approximately May 2014.
	Other Restructure and Asset Impairment Activities
	In order to improve efficiency, labor productivity and competitiveness, we initiated certain limited activities for workforce optimization in 2013. In connection therewith, we incurred charges of $17 million for severance and other employee-related costs in 2013.
	In September 2013, we entered into an agreement to sell our 200mm wafer fabrication equipment in Kiryat Gat, Israel to Intel and to terminate the related facility lease with Intel. Through a series of arrangements, Intel will continue to manufacture wafers for us through 2014. We recognized an impairment charge of $14 million in 2013 to write down the value of these assets to their estimated fair values. The fair value of $38 million was determined primarily based on the expected proceeds of the sale and the fair value of a supply agreement to manufacture NOR flash memory at the facility (Level 3 fair value measurement).

	Noncurrent deferred tax liabilities (included in other noncurrent liabilities)	—			(1		)
	Net deferred tax assets	$	982		$	65
	The valuation allowance is based on our assessment that it is more likely than not that certain deferred tax assets will not be realized. We have a valuation allowance against substantially all U.S. net deferred tax assets as well as $1.5 billion related to our foreign subsidiaries. Elpida represents $912 million of the net deferred tax assets.
	As of August 29, 2013, our federal and state net operating loss carryforwards were $4.2 billion and $2.2 billion, respectively.  If not utilized our federal and state net operating loss carryforwards will expire at various dates through 2033.  As of August 29, 2013, our federal and state tax credit carryforwards were $238 million and $203 million, respectively.  If not utilized our federal and state tax credit carryforwards will expire at various dates through 2033.
	As of August 29, 2013, our foreign net operating loss carryforwards were $7.0 billion, of which $5.9 billion pertains to Elpida. Our foreign net operating loss carryforwards will expire at various dates through 2023. We have placed a valuation allowance against $4.7 billion of these foreign net operating loss carryforwards, of which $3.8 billion pertains to Elpida.  This partial valuation allowance against foreign net operating loss carryforwards, which is primarily attributable to Elpida, results from our current projections of taxable income, being more likely than not, insufficient to utilize the full amount of the net operating loss deferred tax assets.
	We have approximately $67 million of net tax benefits related to excess stock compensation benefits, which are not recorded as deferred tax assets.  These excess stock compensation benefits will be credited to additional paid-in capital when recognized. We use the "with and without" method, as described in ASC 740, for purposes of determining when excess tax benefits have been realized.
	The changes in valuation allowance of $1,693 million and $315 million in 2013 and 2012, respectively, are primarily due to uncertainties of realizing certain U.S. and foreign net operating losses and certain tax credit carryforwards. Elpida represents $1,292 million of the change in the valuation allowance during 2013.
	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 liability.  Remaining undistributed earnings of $1.8 billion as of August 29, 2013 have been indefinitely reinvested; therefore, no provision has been made for taxes due upon remittance of these earnings.  Determination of the amount of unrecognized deferred tax liability on these unremitted earnings is not practicable.
	Below is a reconciliation of the beginning and ending amount of unrecognized tax benefits:
	For the year ended	2013			2012			2011
	Beginning unrecognized tax benefits	$	77		$	121		$	88

Ending unrecognized tax benefits	$	78		$	77		$	121
Included in the unrecognized tax benefits balance as of August 29, 2013, August 30, 2012 and September 1, 2011 were $63 million, $66 million and $113 million, respectively, of unrecognized income tax benefits, which if recognized, would affect our effective tax rate.  We recognize interest and penalties related to income tax matters within income tax expense. As of August 29, 2013, August 30, 2012 and September 1, 2011, accrued interest and penalties related to uncertain tax positions was $16 million, $12 million and $16 million, respectively.
We are unable to reasonably estimate possible increases or decreases in uncertain tax positions that may occur within the next 12 months due to the uncertainty of the timing of the resolution and/or closure on audits.  However, we do not anticipate any such change would be significant.
We currently operate in several tax jurisdictions where we have arrangements that allow us to compute our tax provision at rates below the local statutory rates that expire in whole or in part at various dates through 2026.  These arrangements benefitted our tax provision in 2013, 2012 and 2011 by $141 million ($0.13 per diluted share), $52 million ($0.05 per diluted share) and $72 million ($0.07 per diluted share), respectively.
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 federal and state tax returns remain open to examination for 2009 through 2013.  In addition, tax years open to examination in multiple foreign taxing jurisdictions range from 2005 to 2013.  We are currently under examination in various taxing jurisdictions in which we conduct business operations. We believe that adequate amounts of taxes and related interest and penalties have been provided for, and any adjustments as a result of the examinations are not expected to materially adversely affect our business, results of operations or financial condition.

	IM Flash
	We partnered with Intel to form IMFT in 2006 and IMFS in 2007 to manufacture NAND Flash memory products for the exclusive use of the members. IMFT (and IMFS prior to April 6, 2012) is governed by a Board of Managers. The number of managers appointed by each member to the board varies based on the members' respective ownership interests. The members' ownership percentage is based on contributions to the partnership. We have owned 51% of IMFT from inception through August 29, 2013. Our ownership percentage of IMFS had increased from 51% at inception to 82% as of April 6, 2012 due to a series of contributions by us that were not fully matched by Intel.
	On April 6, 2012, we entered into a series of agreements with Intel to restructure IM Flash. We acquired Intel's remaining 18% interest in IMFS for $466 million. In addition, we acquired IMFT's assets located at our Virginia wafer fabrication facility, for which Intel received a distribution from IMFT of $139 million. For both transactions, the amounts Intel received approximated the book values of Intel's interests in the assets acquired. Additionally, we received a $300 million deposit from Intel which may be applied either to Intel's purchases of NAND Flash under a supply agreement or, under certain circumstances, refunded. As of August 29, 2013, $134 million of the deposit remained to be applied or refunded.
	The agreements also provided for the following:
	•	expansion of the scope of the IMFT joint venture to include certain emerging memory technologies;
	•	supply of NAND Flash memory products and certain emerging memory products to Intel on a cost-plus basis and termination of IMFS's supply agreement with us and Intel;
	•	extension of IMFT's joint venture agreement through 2024;
	•	certain buy-sell rights, commencing in 2015, pursuant to which Intel may elect to sell to us, or we may elect to purchase from Intel, Intel’s interest in IMFT (if Intel so elects, we would set the closing date of the transaction within two years following such election and could elect to receive financing from Intel for one to two years);
	•	financing of $65 million provided by Intel to us under a two-year senior unsecured promissory note, payable with interest in approximately equal quarterly installments (as of August 29, 2013, $25 million of the note was outstanding); and
	•	termination of IMFT's lease to use approximately 50% of our Virginia fabrication facility, which resulted in a charge to other operating expense of $17 million in 2012.
	The following table presents IM Flash's distributions to and contributions from its members ("IM Flash" includes both IMFT and IMFS for all periods prior to April 6, 2012 and includes only IMFT for the period after April 6, 2012):
	For the year ended		2013		2012		2011
	IM Flash distributions to Micron		$	38	$	439	$	234
	IM Flash distributions to Intel		37		391		225
	Micron contributions to IM Flash		12		151		1,580
	Intel contributions to IM Flash		11		177		—
	IM Flash sells products to the joint venture members generally in proportion to their ownership interests at long-term negotiated prices approximating cost. Due to the changes in ownership, our share of IMFS output grew from 51% in the first quarter of 2011 to 78% in the second quarter of 2012. As a result of our restructuring of IM Flash on April 6, 2012, Intel has no continuing rights to the output from the IMFS and Virginia facilities. Intel continues to receive output from IMFT in proportion to its ownership interest at long-term negotiated prices approximating cost and, subsequent to April 6, 2012, also purchases NAND Flash products from us under a cost-plus supply arrangement. Aggregate sales of NAND Flash products to Intel (including sales by IMFT at prices approximating cost and sales by us under the cost-plus supply agreement) were $849 million, $986 million and $884 million for 2013, 2012 and 2011, respectively. Receivables from Intel for sales of NAND Flash products as of August 29, 2013 and August 30, 2012, were $198 million and $103 million, respectively.
	As a result of changes to the timing of the passage of title in the IMFT supply agreement with Intel, effective April 6, 2012, sales are now recognized upon completion of wafer fabrication, rather than after backend assembly and test are completed. As a result, we sold $97 million of backend inventories, which generated a one-time increase in NAND sales and reduction in work in process inventories in 2012.
	The following table presents the assets and liabilities of IMFT included in our consolidated balance sheets, excluding intercompany balances:
	As of		2013		2012

	Amounts exclude intercompany balances that were eliminated in our consolidated balance sheets.
	Our ability to access IMFT's cash and other assets through cash dividends, loans or advances, including to finance our other operations, is subject to agreement by Intel. Creditors of IMFT have recourse only to its assets and do not have recourse to any other of our assets.
	IM Flash manufactures NAND Flash memory products using designs and technology we develop with Intel. We generally share product design and other NAND Flash R&D costs with Intel. The April 6, 2012 agreements with Intel expanded our NAND Flash R&D cost-sharing agreement with Intel to include certain emerging memory technologies, but did not change the cost-sharing percentage. R&D expenses were reduced by reimbursements from Intel of $127 million, $87 million and $95 million for 2013, 2012 and 2011, respectively.
	MP Mask
	In 2006, we formed a joint venture with Photronics to produce photomasks for leading-edge and advanced next generation semiconductors.  At inception and through August 29, 2013, we owned 50.01% and Photronics owned 49.99% of MP Mask.  We contributed $21 million to MP Mask and Photronics contributed $20 million to MP Mask in 2012. In connection with the formation of the joint venture, we received $72 million in 2006 in exchange for entering into a license agreement with Photronics, which is being recognized over the term of the 10-year agreement.  Deferred income and other noncurrent liabilities included an aggregate of $19 million and $26 million as of August 29, 2013 and August 30, 2012, respectively, related to this agreement. We purchase a substantial majority of the reticles produced by MP Mask pursuant to a supply arrangement.
	Total MP Mask assets and liabilities included in our consolidated balance sheets were as follows:
	As of		2013		2012
	Current assets		$	26	$	19
	Noncurrent assets (primarily property, plant and equipment)		182		170
	Current liabilities		25		12
	Amounts exclude intercompany balances that were eliminated in our consolidated balance sheets.
	Creditors of MP Mask have recourse only to the assets of MP Mask and do not have recourse to any other of our assets.
	Through February 24, 2012, we leased to Photronics a facility to produce photomasks under an operating lease. On February 24, 2012, we sold the facility to Photronics for $35 million. The proceeds were equal to our net carrying value and no gain or loss was realized from the sale.

	Embedded Solutions Group ("ESG"): Includes DRAM, NAND Flash and NOR Flash products sold into automotive and industrial applications, as well as NOR and NAND Flash sold to consumer electronics, networking, PC and server markets.
	Our other operations do not meet the quantitative thresholds of a reportable segment and are reported under All Other.
	Certain operating expenses directly associated with the activities of a specific reportable segment are charged to that segment. Other indirect operating expenses (income) are generally allocated to the reportable segments based on their respective percentage of cost of goods sold or forecasted wafer production. In 2013, we reclassified the (gains) losses from changes in currency exchange rates from other operating (income) expense, net to other non-operating income (expense), net in the consolidated statements of income. As a result, the (gains) losses from changes in currency exchange rates have been reclassified out of operating income (loss) for our segments for 2012 and 2011.
	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 operating segments.  There are no differences in the accounting policies for segment reporting and our consolidated results of operations.

	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 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 and interest rate swap hedges is limited and the notional amount is relatively large. We seek to mitigate such risk by limiting our counterparties to major financial institutions. The 2031 Capped Calls, 2032 Capped Calls and 2033 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. (See "Shareholders' Equity – Capped Calls" note.)

Basis of Presentation
Micron Technology, Inc., ("Micron") a Delaware corporation, was incorporated in 1978.  Micron is the parent company of it's consolidated subsidiaries and, together with it's consolidated subsidiaries, is one of the world's leading providers of advanced semiconductor solutions.
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 (U.S.) 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 August 29, 2013.

Micron' senior notes are unsecured obligations ranking 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 Intel note of Micron are structurally subordinated to $1,863 million of other notes payable of its subsidiaries and capital lease obligations. MTI guarantees certain debt obligations of its subsidiaries. MTI does not guarantee the Elpida creditor installment payments. As of August 29, 2013, Micron had guaranteed $701 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
We have various capital lease obligations due in periodic installments with a weighted-average remaining term of 2.9 years and weighted-average effective interest rates of 4.7% as of August 29, 2013 and 4.8% as of August 30, 2012. In 2013, we received $126 million in proceeds from equipment sale-leaseback transactions and as a result recorded capital lease obligations aggregating $126 million at a weighted-average effective interest rate of 4.3%, payable in periodic installments through July, 2017. In 2012, we received $439 million in proceeds from equipment sale-leaseback transactions and as a result recorded capital lease obligations aggregating $439 million at a weighted-average effective interest rate of 4.1%, payable in periodic installments through August, 2016.
As of August 29, 2013 and August 30, 2012, production equipment with a carrying value of $458 million and $491 million, respectively, was collateral for Micron's capital leases.
Convertible Senior Notes and Intel Senior Note

Commitments
Micron has various financial guarantees which are 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 purchases or sales, as applicable, by Micron or any of its subsidiaries, and occasionally Micron may be required to perform under such agreements on behalf of its subsidiaries.
As of August 29, 2013, the maximum potential amount of future payments Micron could have been required to make under its debt guarantees was approximately $705 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 collateralized by the 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 December, 2014 and January, 2018. Micron also guarantees credit facilities that provide for up to $408 million of additional financing. As of August 29, 2013, no amounts had been drawn under these credit facilities.
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 over drafting their bank accounts. The majority of these guarantees have no contractual expiration.
We have agreed, subject to certain conditions, to provide certain support to Elpida with respect to obtaining financing for working capital purposes and capital expenditures. In addition, we agreed, subject to certain conditions, to use reasonable best efforts to assist the Elpida Companies in financing up to 64 billion yen (or the equivalent of approximately $655 million) of eligible capital expenditures incurred through June 30, 2014, which may include us providing payment guarantees of third party financing under certain circumstances or direct financial support from Micron Technology, Inc. or one of its subsidiaries. For further information, see "Item 8. Financial Statements and Supplementary Data – Acquisition of Elpida Memory, Inc." to Micron's consolidated financial statements.
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 it's 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. We are currently a party to various litigation regarding patent, antitrust, securities, commercial and other matters arising from the normal course of business, none of which is expected to have a material adverse effect on Micron's business, results of operations or financial condition. Micron is a party to the matters listed in the "Contingencies" note in the consolidated financial statements, with the exception of the patent infringement case Tessera Inc. filed on December 7, 2007 against Elpida Memory, Inc., Elpida Memory (USA) Inc., and numerous other defendants, and the complaint filed on July 12, 2013 by seven former shareholders of Elpida against the board of directors of Elpida as of February 2013. For further information, see the Consolidated Financial Statements, "Contingencies" note.
Related Party Transaction
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. As of August 29, 2013, Micron held a 31% ownership interest in Aptina Imaging Corporation ("Aptina") and a 50% ownership interest in Transform Solar Pty Ltd. Net sales included sales to consolidated subsidiaries of $4,190 million, $4,148 million and $5,718 million for 2013, 2012 and 2011, respectively. Net sales for 2013, 2012 and 2011 also included $182 million, $372 million and $349 million, respectively, for sale of products to Aptina. For further information regarding transactions between Micron and its equity method investees, see the Consolidated Financial Statements, "Equity Method Investments – Other" note.

Significant_Accounting_Policie1

Significant Accounting Policies (Policies)	12 Months Ended
	Aug. 29, 2013
Policy Text Block [Abstract]
Basis of Presentation	Basis of Presentation: We are one of the world's leading providers of advanced semiconductor solutions. Through our worldwide operations, we manufacture and market a full range of DRAM, NAND Flash and NOR Flash memory, as well as other innovative memory technologies, packaging solutions and semiconductor systems for use in leading-edge computing, consumer, networking, automotive, industrial, embedded and mobile products. 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, including restructure and asset impairment activities prior to 2013 that were previously reported in other operating (income) expense, net. In 2013, we reclassified gains and losses from changes in currency exchange rates in order to improve comparability with our industry peers. As a result of the reclassification, $6 million of losses in both 2012 and 2011, were reclassified from the amounts previously reported in other operating (income) expense, net to other non-operating income (expense), net. Certain deferred tax assets and liabilities in prior years were corrected with corresponding changes in the valuation allowance, resulting in no change to net deferred tax assets. The change in these items was not material for any period presented.
Fiscal Period	Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Our fiscal years 2013, 2012 and 2011 each contained 52 weeks. All period references are to our fiscal periods unless otherwise indicated. Our recently acquired subsidiary, Elpida Memory, Inc., has been consolidated based on its fiscal year ending on August 31, 2013.
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.
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 material.
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.  Since we are unable to estimate returns and changes in market price, and therefore the price is not fixed or determinable, sales made under agreements allowing pricing protection or rights of return (other than for product warranty) are deferred until customers have resold the product.
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 these cost-sharing arrangements are reflected as a reduction of research and development expense.  (See "Equity Method Investments" and "Consolidated Variable Interest Entities – IM Flash" notes.)
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.)
Stock Repurchases	Stock Repurchases: When we repurchase and retire our common stock, any excess of the repurchase price paid over par value is allocated between paid-in capital and retained earnings.
Functional Currency	Functional Currency: The U.S. dollar is the functional currency for all of our consolidated operations.
Cash and Cash Equivalents	Cash equivalents include highly liquid short-term investments with original maturities to us of three months or less, readily convertible to known amounts of cash.
Investments	Investments with original maturities greater than three months and remaining maturities 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.
Derivative and Hedging Instruments	Derivative and Hedging Instruments: We use derivative financial instruments to manage certain exposures to fluctuating currency exchange and interest rates. Our derivatives consist primarily of forward and option currency contracts and 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) for 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 and included for options.
	We seek to enter into master netting arrangements to mitigate credit risk in derivative 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 under these arrangements have been presented in our consolidated balance sheet on a net basis.
	(See "Derivative Financial Instruments – Currency Derivatives with Hedge Accounting Designation" note.)
Inventories	Inventories: Inventories are stated at the lower of average cost or market value.  Cost includes labor, material and overhead costs, including product and process technology costs.  Determining market values of inventories involves numerous judgments, including projecting average selling prices and sales volumes for future periods and costs to complete products in work in process inventories.  When market values are below costs, we record a charge to cost of goods sold to write down inventories to their estimated market value in advance of when the inventories are actually sold.  The major characteristics considered in determining inventory categories for purposes of determining the lower of cost or market value are product type and markets. Prior to the third quarter of 2013, inventory was categorized as memory (primarily DRAM and NAND Flash and NOR Flash) and imaging products for purposes of determining lower of average cost or market. Due to the sale on May 3, 2013 of Micron Technology Italia, S.r.l. ("MIT") and our assignment to LFoundry Marsica S.r.l. ("LFoundry") of our supply agreement with Aptina Imaging Corporation ("Aptina") for CMOS image sensors, we ceased manufacturing CMOS image sensors subsequent to that date and no longer have imagining inventory for purposes of determining lower of average cost or market.
Product and Process Technology	Product and Process Technology: Costs incurred to acquire product and process technology or to patent technology are capitalized and amortized on a straight-line basis over periods ranging up to 10 years.  We capitalize a portion of costs incurred based on the historical and projected patents issued as a percent of patents we file.  Capitalized product and process technology costs are amortized over the shorter of (i) the estimated useful life of the technology, (ii) the patent term or (iii) the term of the technology agreement.  Fully-amortized assets are removed from product and process technology and accumulated amortization.
Property, plant and equipment	Property, Plant and Equipment: Property, plant and equipment are stated at cost and depreciated using the straight-line method over estimated useful lives of generally 10 to 30 years for buildings, generally 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 or equipment is retired or otherwise disposed, the net book value of the asset is removed and we recognize any gain or loss in our results of operations.
	We capitalize interest on borrowings during the active construction period of capital projects.  Capitalized interest is added to the cost of the underlying assets and amortized over the useful lives of the assets.

Variable Interest Entities (Policies)	12 Months Ended

Policy Text Block [Abstract]
Variable Interest Entities	We have interests in entities that are Variable Interest Entities ("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.
