Variable Interest Entities

Variable Interest Entities	9 Months Ended
	Jun. 01, 2017
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities We have interests in entities that are VIEs. If we are the primary beneficiary of a VIE, we are required to consolidate it. To determine if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing, and other applicable agreements and circumstances. Our assessments of whether we are the primary beneficiary of our VIEs require significant assumptions and judgments. Unconsolidated VIEs Inotera : Prior to our acquisition of the remaining interest in Inotera on December 6, 2016, Inotera was a VIE because of the terms of its supply agreement with us. We had determined that we did not have the power to direct the activities of Inotera that most significantly impacted its economic performance, primarily due to limitations on our governance rights that required the consent of other parties for key operating decisions and due to Inotera's dependence on Nanya for financing and the ability of Inotera to operate in Taiwan. Therefore, we did not consolidate Inotera and we accounted for our interest under the equity method. (See "Acquisition of Inotera" and "Equity Method Investments – Inotera" notes.) EQUVO : EQUVO HK Limited ("EQUVO"), a special purpose entity, was created to facilitate an equipment sale-leaseback financing transaction between us and a consortium of financial institutions. Neither we nor the financing entities have an equity interest in EQUVO. EQUVO was a VIE because its equity was not sufficient to permit it to finance its activities without additional support from the financing entities and because the third-party equity holder lacked characteristics of a controlling financial interest. By design, the arrangement with EQUVO was merely a financing vehicle and we did not bear any significant risks from variable interests with EQUVO. Therefore, we had determined that we did not have the power to direct the activities of EQUVO that most significantly impact its economic performance and we did not consolidate EQUVO. In February 2017, we completed all of our obligations under the sale-leaseback financing and no longer have any variable interests in EQUVO. SC Hiroshima Energy Corporation : SC Hiroshima Energy Corporation ("SCHE") is an entity created to construct and operate a cogeneration, electrical power plant to support our wafer manufacturing facility in Hiroshima, Japan. We do not have an equity interest in SCHE. SCHE is a VIE due to the nature of its tolling agreements with us and our option to purchase SCHE's assets. We do not control the operation and maintenance of the plant, which we have determined are the activities of SCHE that most significantly impact its economic performance. Therefore, we do not consolidate SCHE. PTI Xi'an : Powertech Technology Inc. Xi'an ("PTI Xi'an") is a wholly-owned subsidiary of Powertech Technology Inc. ("PTI") and was created to provide assembly services to us at our manufacturing site in Xi'an, China. We do not have an equity interest in PTI Xi'an. PTI Xi'an is a VIE because of the terms of its service agreement with us and its dependency on PTI to finance its operations. We have determined that we do not have the power to direct the activities of PTI Xi'an that most significantly impact its economic performance, primarily because we have no governance rights. Therefore, we do not consolidate PTI Xi'an. Consolidated VIE IMFT : IMFT is a VIE because all of its costs are passed to us and its other member, Intel, through product purchase agreements and because IMFT is dependent upon us or Intel for additional cash requirements. The primary activities of IMFT are driven by the constant introduction of product and process technology. Because we perform a significant majority of the technology development, we have the power to direct its key activities. In addition, IMFT manufactures certain products exclusively for us using our technology. We consolidate IMFT because we have the power to direct the activities of IMFT that most significantly impact its economic performance and because we have the obligation to absorb losses and the right to receive benefits from IMFT that could potentially be significant to it. (See "Equity – Noncontrolling Interests in Subsidiaries – IMFT" note.)

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04 – Simplifying the Test for Goodwill Impairment , which modified the goodwill impairment test and required an entity to write down the carrying value of goodwill up to the amount by which the carrying amount of a reporting unit exceeded its fair value. We adopted this ASU as of the beginning of the fourth quarter of 2017 in connection with our annual impairment test. The adoption of the ASU itself did not have a material impact on our financial statements. In March 2016, the FASB issued ASU 2016-09 – Improvements to Employee Share-Based Payment Accounting , which simplified several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, forfeitures, and classification within the statement of cash flows. We adopted this ASU as of the beginning of the first quarter of 2017 and elected to account for forfeitures when they occur, on a modified retrospective basis. As a result of the adoption of this ASU, in the first quarter of 2017, we recognized deferred tax assets of $325 million for the excess tax benefits that arose directly from tax deductions related to equity compensation greater than amounts recognized for financial reporting and also recognized an increase of an equal amount in the valuation allowance against those deferred tax assets. The adoption did not have any other material impacts on our financial statements. In April 2015, the FASB issued ASU 2015-05 – Customer's Accounting for Fees Paid in a Cloud Computing Arrangement , which provided additional guidance to customers about whether a cloud computing arrangement included a software license. Under ASU 2015-05, cloud computing arrangements that contain a software license should be accounted for in a manner consistent with the acquisition of other software licenses, otherwise customers should account for the arrangement as a service contract. ASU 2015-05 also removed the requirement to analogize to ASC 840-10 – Leases , to determine the asset acquired in a software licensing arrangement. We adopted this ASU as of the beginning of the first quarter of 2017 on a prospective basis. The adoption of this ASU did not have a material impact on our financial statements. In February 2015, the FASB issued ASU 2015-02 – Amendments to the Consolidation Analysis , which amended the consolidation requirements in Accounting Standards Codification 810 – Consolidation . ASU 2015-02 made targeted amendments to the consolidation guidance for VIEs. We adopted this ASU as of the beginning of the first quarter of 2017 under a modified-retrospective approach. The adoption of this ASU did not have an impact on our financial statements.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In November 2016, the FASB issued ASU 2016-18 – Restricted Cash , which requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. This ASU will be effective for us in the first quarter of 2019 with early adoption permitted and requires retrospective adoption. We are evaluating the timing of our adoption of this ASU on our financial statements. In October 2016, the FASB issued ASU 2016-16 – Intra-Entity Transfers Other Than Inventory , which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU will be effective for us in the first quarter of 2019 with early adoption permitted and requires modified retrospective adoption. We are evaluating the timing and effects of our adoption of this ASU on our financial statements. In June 2016, the FASB issued ASU 2016-13 – Measurement of Credit Losses on Financial Instruments , which requires a financial asset (or a group of financial assets) measured on the basis of amortized cost to be presented at the net amount expected to be collected. This ASU requires that the income statement reflect the measurement of credit losses for newly recognized financial assets as well as the expected increases or decreases of expected credit losses that have taken place during the period. This ASU requires that credit losses of debt securities designated as available-for-sale be recorded through an allowance for credit losses and limits the credit loss to the amount by which fair value is below amortized cost. This ASU will be effective for us in the first quarter of 2021; however, we are permitted to adopt this ASU as early as the first quarter of 2020. This ASU requires modified retrospective adoption, with prospective adoption for debt securities for which an other-than-temporary impairment had been recognized before the effective date. We are evaluating the timing and effects of our adoption of this ASU on our financial statements. In February 2016, the FASB issued ASU 2016-02 – Leases , which amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset and corresponding liability, measured at the present value of the lease payments. This ASU will be effective for us in the first quarter of 2020 with early adoption permitted and requires modified retrospective adoption. The adoption of this ASU will result in an increase to our consolidated balance sheets for these right-of-use assets and corresponding liabilities. We are evaluating the timing and other effects of our adoption of this ASU on our financial statements. In January 2016, the FASB issued ASU 2016-01 – Recognition and Measurement of Financial Assets and Financial Liabilities , which provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. This ASU will be effective for us in the first quarter of 2019 and requires modified retrospective adoption. We are evaluating the effects of our adoption of this ASU on our financial statements. In May 2014, the FASB issued ASU 2014-09 – Revenue from Contracts with Customers , which supersedes nearly all existing revenue recognition guidance under generally accepted accounting principles in the U.S. The core principal of this ASU, as amended, is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. We are required to adopt this ASU in the first quarter of 2019; however, we are permitted to adopt this ASU as early as the first quarter of 2018. This ASU allows for either full retrospective or modified retrospective adoption. We expect that, as a result of the adoption of this ASU, the timing of recognizing revenue from sales of products to our distributors under agreements allowing rights of return or price protection will be generally earlier than under the existing revenue recognition guidance. After adoption, the impact of this change in any reporting period would be the net effect of changes to revenue recognized as of the beginning and end of each period. Revenue recognized upon resale by our customers with these rights was 19% and 21% of total sales for the third quarter and first nine months of 2017 , respectively, and 26% and 24% for the third quarter and first nine months of 2016 , respectively. We are evaluating the timing, method, and other effects of our adoption of this ASU on our financial statements.

Acquisition of Inotera

Acquisition of Inotera	9 Months Ended

Inotera
Business Acquisition [Line Items]
Acquisition of Inotera	Acquisition of Inotera Through December 6, 2016, we held a 33% ownership interest in Inotera, now known as Micron Technology Taiwan, Inc. ("MTTW"), Nanya and certain of its affiliates held a 32% ownership interest, and the remaining ownership interest was publicly held. On December 6, 2016, we acquired the 67% remaining interest in Inotera not owned by us (the "Inotera Acquisition") and began consolidating Inotera's operating results. The cash paid for the Inotera Acquisition was funded, in part, with proceeds from the 2021 MSTW Term Loan and the sale of the Micron Shares (as defined below) to Nanya. Inotera manufactures DRAM products at its 300mm wafer fabrication facility in Taoyuan City, Taiwan, and sold such products exclusively to us through supply agreements. SG&A expenses for the first six months of 2017 and for full fiscal 2016 included transaction costs of $13 million and $3 million , respectively, incurred in connection with the Inotera Acquisition. In connection with the Inotera Acquisition, we revalued our previously-held 33% equity interest to its fair value. In determining the fair value, we used various valuation techniques, including the share price of Inotera prior to the announcement of the Inotera Acquisition and discounted cash flow projections using inputs including discount rate and terminal growth rate (Level 3). As a result, we recognized a non-operating gain of $71 million in the second quarter of 2017. In connection with the Inotera Acquisition, we sold 58 million shares of our common stock to Nanya (the "Micron Shares") and received cash proceeds of $986 million . Because the sale of the Micron Shares to Nanya was contemporaneous with, and contingent upon, the closing the Inotera Acquisition, the issuance of the Micron Shares was treated in purchase accounting as a non-cash exchange for a portion of the shares of Inotera held by Nanya. The Micron Shares were issued in a transaction exempt from the registration requirements of the Securities Act of 1933, as amended, and subject to certain restrictions on transfers. To reflect the lack of transferability, the fair value of the Micron Shares (based on the trading price of our common stock on the acquisition date) was reduced by a discount of $81 million , based on the implied volatility derived from traded options on our stock and on the duration of the lack of transferability (Level 2). We provisionally estimated the fair value of the Inotera assets acquired and liabilities assumed as of the December 6, 2016 acquisition date. In the third quarter of 2017, we incorporated additional information in our analysis about facts and circumstances that existed as of the acquisition date and adjusted our provisional values, which resulted in a decrease in the amount of purchase price allocated to property, plant, and equipment of $59 million and increases in the amounts allocated to other noncurrent assets of $13 million , deferred income taxes of $8 million , and goodwill of $38 million . The allocation of purchase price to assets acquired and liabilities assumed of Inotera could further change as additional information becomes available. The consideration and provisional valuation of assets acquired and liabilities assumed, as adjusted in the third quarter of 2017, are as follows: Consideration Cash paid for Inotera Acquisition $ 4,099 Less cash received from selling Micron Shares (986 ) Net cash paid for Inotera Acquisition 3,113 Fair value of our previously-held equity interest in Inotera 1,441 Fair value of Micron Shares exchanged for Inotera shares 995 Other 3 Payments attributed to intercompany balances with Inotera (361 ) $ 5,191 Assets acquired and liabilities assumed Cash and equivalents $ 118 Inventories 285 Other current assets 27 Property, plant, and equipment 3,722 Deferred tax assets 82 Goodwill 1,124 Other noncurrent assets 130 Accounts payable and accrued expenses (232 ) Debt (56 ) Other noncurrent liabilities (9 ) $ 5,191 As a result of the Inotera Acquisition, we expect to experience greater operational flexibility to drive new technology in products manufactured by Inotera, optimize the deployment of our cash flows across our operations, and enhance our ability to adapt our product offerings to changes in market conditions. As a result of these synergies, we allocated goodwill of $829 million , $198 million , and $97 million to CNBU, MBU, and EBU, respectively. Goodwill resulting from the Inotera Acquisition is not deductible for Taiwan corporate income tax purposes; however, it is deductible for Taiwan surtax purposes. Unaudited Pro Forma Financial Information The following unaudited pro forma financial information presents the combined results of operations as if the Inotera Acquisition had occurred on September 4, 2015. The pro forma financial information includes the accounting effects of the business combination, including adjustments for depreciation of property, plant, and equipment, interest expense, elimination of intercompany activities, and revaluation of inventories. The unaudited pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the Inotera Acquisition occurred on September 4, 2015.

The pro forma information for 2016 includes our results for the quarter and nine months ended June 2, 2016 , the results of Inotera for the quarter and nine months ended May 31, 2016, and the adjustments described above. Technology Transfer and License Agreements with Nanya Effective December 6, 2016, under the terms of technology transfer and license agreements, Nanya has options to require us to transfer to Nanya for Nanya's use certain technology and deliverables related to the next DRAM process node generation after our 20nm process node (the "1X Process Node") and the next DRAM process node generation after the 1X Process Node. Under the terms of the agreements, Nanya would pay royalties to us for a license to the transferred technologies based on revenues from products utilizing the technologies, subject to specified caps, and we would also receive an equity interest in Nanya upon the achievement of certain milestones.

(2) The fair value of Level 1 securities is measured based on quoted prices in active markets for identical assets. (3) The fair value of Level 2 securities is measured using information obtained from pricing services, which obtain quoted market prices for similar instruments, non-binding market consensus prices that are corroborated by observable market data, or various other methodologies, to determine the appropriate value at the measurement date. We perform supplemental analysis to validate information obtained from these pricing services. No adjustments were made to such pricing information as of June 1, 2017 . Proceeds from sales of available-for-sale securities were $194 million and $742 million for the third quarter and first nine months of 2017 , respectively, and $902 million and $1.89 billion for the third quarter and first nine months of 2016 , respectively. Gross realized gains and losses from sales of available-for-sale securities were not material for any period presented. As of June 1, 2017 , there were no available-for-sale securities that had been in a loss position for longer than 12 months. Restricted cash, included in other noncurrent assets and excluded from the table above, was $98 million and $122 million as of June 1, 2017 and September 1, 2016 , respectively.

Historically, we accounted for our interest in Inotera on a two-month lag under the equity method. As a result of the Inotera Acquisition, we account for Inotera without a lag, consistent with our other wholly-owned subsidiaries. From January 2013 through December 2015, we purchased all of Inotera's DRAM output under supply agreements at prices reflecting discounts from market prices for our comparable components. After December 2015 and until our acquisition of the remaining interest in Inotera, the price for DRAM products purchased by us was based on a formula that equally shared margin between Inotera and us. We purchased $504 million of DRAM products from Inotera in the first quarter of 2017 and $348 million and $1.05 billion in the third quarter and first nine months of 2016 , respectively. Tera Probe In the third quarter of 2017, we sold our 40% interest in Tera Probe, which provides semiconductor wafer testing and probe services to us and others, in a transaction that included the pending sale of our assembly and test facility located in Akita, Japan. (See "Restructure and Asset Impairments" note.) In the first quarter of 2017 and third quarter of 2016, we recorded impairment charges of $16 million and $25 million , respectively, within equity in net income (loss) of equity method investees to write down the carrying value of our investment in Tera Probe to its then fair value based on its trading price (Level 1). We incurred manufacturing costs for services performed by Tera Probe of $15 million and $47 million in the third quarter and first nine months of 2017 , respectively, and $19 million and $58 million in the third quarter and first nine months of 2016 , respectively.

The closing price of our common stock also exceeded the thresholds for the calendar quarter ended June 30, 2017; therefore, these notes are convertible by the holders through September 30, 2017. The 2033 Notes were classified as current as of June 1, 2017 because the terms of these notes require us to pay cash for the principal amount of any converted notes and holders of these notes had the right to convert their notes as of that date. In addition, the holders of the 2033E Notes can require us to repurchase for cash all or a portion of the 2033E Notes on February 15, 2018. Debt Restructure On April 11, 2017, we repurchased $631 million of principal amount of our 2025 Notes (carrying value of $625 million ) and $321 million of principal amount of our 2026 Notes (carrying value of $318 million ) for an aggregate of $1.00 billion in cash. In connection with the transactions, we recognized a non-operating loss of $60 million in the third quarter of 2017. Capital Lease Obligations In the third quarter of 2017 , we recorded capital lease obligations aggregating $84 million at a weighted-average effective interest rate of 6.5% and a weighted-average expected term of 5 years. In the first nine months of 2017 , we recorded capital lease obligations aggregating $217 million . 2021 MSAC Senior Secured Term Loan In November 2016, we entered into a five -year variable-rate facility agreement to obtain up to $800 million of financing, collateralized by certain production equipment. On March 6, 2017 and December 2, 2016, we drew $175 million and $450 million , respectively, under the 2021 MSAC Term Loan. On June 5, 2017, subsequent to the end of our third quarter of 2017, we drew the remaining $175 million under this facility. Interest is payable quarterly at a per annum rate equal to three -month LIBOR plus 2.4% . Principal is payable in 16 equal quarterly installments beginning in March 2018. The 2021 MSAC Term Loan contains covenants which are customary for financings of this type, including negative covenants that limit or restrict our ability to create liens or dispose of the equipment securing the facility agreement. The 2021 MSAC Term Loan also contains a covenant that the ratio of the outstanding loan to the fair value of the equipment collateralizing the loan not exceed 0.8 . If such ratio is exceeded, we are required to grant a security interest in additional equipment and/or prepay the 2021 MSAC Term Loan in an amount sufficient to reduce such ratio to 0.8 or less. The 2021 MSAC Term Loan also contains customary events of default which could result in the acceleration of all amounts to be immediately due and payable. The 2021 MSAC Term Loan is guaranteed by Micron. 2021 MSTW Senior Secured Term Loan In connection with the Inotera Acquisition, on December 6, 2016, we drew 80 billion New Taiwan dollars under a collateralized, five -year term loan that bears interest at a variable per annum rate equal to the three -month or six -month TAIBOR, at our option, plus a margin of 2.05% . Principal under the 2021 MSTW Term Loan is payable in six equal semi-annual installments, commencing in June 2019, through December 2021. The 2021 MSTW Term Loan is collateralized by certain assets, including a real estate mortgage on MTTW's main production facility and site, a chattel mortgage over certain equipment of MTTW, all of the stock of our MSTW subsidiary, and the 82% of stock of MTTW owned by MSTW. The 2021 MSTW Term Loan is guaranteed by Micron. The 2021 MSTW Term Loan contains affirmative and negative covenants, including covenants that limit or restrict our ability to create liens in or dispose of collateral securing obligations under the 2021 MSTW Term Loan, mergers involving MSTW and/or MTTW, loans or guarantees to third parties by MTTW and/or MSTW, and MSTW's and/or MTTW's distribution of cash dividends. The 2021 MSTW Term Loan also contains financial covenants, which are tested semi-annually, as follows: • MSTW must maintain a consolidated ratio of total liabilities to adjusted EBITDA not higher than 5.5 x in 2017 and 2018, and not higher than 4.5 x in 2019 through 2021; • MSTW must maintain adjusted consolidated tangible net worth of not less than 4.0 billion New Taiwan dollars in 2017 and 2018, not less than 6.5 billion New Taiwan dollars in 2019 and 2020, and not less than 12.0 billion New Taiwan dollars in 2021; • on a consolidated basis, Micron must maintain a ratio of total liabilities to adjusted EBITDA not higher than 3.5 x in 2017, not higher than 3.0 x in 2018 and 2019, and not higher than 2.5 x in 2020 and 2021; and • on a consolidated basis, Micron must maintain adjusted tangible net worth not less than $9.0 billion in 2017, not less than $12.5 billion in 2018 and 2019, and not less than $16.5 billion in 2020 and 2021. If MSTW fails to maintain a required financial covenant, the interest rate will be increased by 0.25% until such time as the required financial ratios are maintained. If MSTW's failure continues for two consecutive semi-annual periods, such failure will constitute an event of default that could result in all obligations owed under the 2021 MSTW Term Loan being accelerated to be immediately due and payable. Micron's failure to maintain a required financial covenant will only result in a 0.25% increase to the interest rate but will not constitute an event of default. The 2021 MSTW Term Loan also contains customary events of default. Convertible Senior Notes As of June 1, 2017 , the trading price of our common stock was higher than the initial conversion prices of our convertible notes. As a result, the conversion values for these notes exceeded the principal amounts by $1.77 billion as of June 1, 2017 . 2022 Senior Secured Term Loan B Repricing Amendment On April 26, 2017, we amended our 2022 Term Loan B, substantially all of which was treated as a debt modification, to reduce the margins added to the base rate from 2.75% to 1.5% and to the adjusted LIBOR rate from 3.75% to 2.5% . In October 2016, we amended our 2022 Term Loan B, substantially all of which was treated as a debt modification, to reduce the margins added to the base rate from 5.00% to 2.75% and to the adjusted LIBOR rate from 6.00% to 3.75% .

Loss Contingency [Abstract]
Contingencies	Contingencies We have accrued a liability and charged operations for the estimated costs of adjudication or settlement of various asserted and unasserted claims existing as of the 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-tech industries, from time to time others have asserted, and may in the future assert, that our products or manufacturing processes infringe their intellectual property rights. On November 21, 2014, Elm 3DS Innovations, LLC ("Elm") filed a patent infringement action against Micron, MSP, and Micron Consumer Products Group, Inc. in the U.S. District Court for the District of Delaware. On March 27, 2015, Elm filed an amended complaint against the same entities. The amended complaint alleges that unspecified semiconductor products of ours that incorporate multiple stacked die infringe thirteen U.S. patents and seeks damages, attorneys' fees, and costs. On December 15, 2014, Innovative Memory Solutions, Inc. filed a patent infringement action against Micron in the U.S. District Court for the District of Delaware. The complaint alleges that a variety of our NAND products infringe eight U.S. patents and seeks damages, attorneys' fees, and costs. On June 24, 2016, the President and Fellows of Harvard University filed a patent infringement action against Micron in the U.S. District Court for the District of Massachusetts. The complaint alleges that a variety of our DRAM products infringe two U.S. patents and seeks damages, injunctive relief, and other unspecified relief. Among other things, the above lawsuits pertain to certain of our DDR DRAM, DDR2 DRAM, DDR3 DRAM, DDR4 DRAM, SDR SDRAM, PSRAM, RLDRAM, LPDRAM, NAND, and certain other memory products we manufacture, which account for a significant portion of our net sales. We are unable to predict the outcome of assertions of infringement made against us and therefore cannot estimate the range of possible loss. A determination that our products or manufacturing processes infringe the intellectual property rights of others or entering into a license agreement covering such intellectual property could result in significant liability and/or require us to make material changes to our products and/or manufacturing processes. Any of the foregoing could have a material adverse effect on our business, results of operations, or financial condition. Qimonda On January 20, 2011, Dr. Michael Jaffé, administrator for Qimonda insolvency proceedings, filed suit against Micron and Micron Semiconductor B.V., our Netherlands subsidiary ("Micron B.V."), in the District Court of Munich, Civil Chamber. The complaint seeks to void under Section 133 of the German Insolvency Act a share purchase agreement between Micron B.V. and Qimonda signed in fall 2008 pursuant to which Micron B.V. purchased substantially all of Qimonda's shares of Inotera (the "Inotera Shares"), representing approximately 18% of Inotera's outstanding shares as of June 1, 2017 and seeks an order requiring us to re-transfer those shares to the Qimonda estate. The complaint also seeks, among other things, to recover damages for the alleged value of the joint venture relationship with Inotera and to terminate under Sections 103 or 133 of the German Insolvency Code a patent cross-license between us and Qimonda entered into at the same time as the share purchase agreement. Following a series of hearings with pleadings, arguments, and witnesses on behalf of the Qimonda estate, on March 13, 2014, the Court issued judgments: (1) ordering Micron B.V. to pay approximately $1 million in respect of certain Inotera shares sold in connection with the original share purchase; (2) ordering Micron B.V. to disclose certain information with respect to any Inotera Shares sold by it to third parties; (3) ordering Micron B.V. to disclose the benefits derived by it from ownership of the Inotera Shares, including in particular, any profits distributed on such shares and all other benefits; (4) denying Qimonda's claims against Micron for any damages relating to the joint venture relationship with Inotera; and (5) determining that Qimonda's obligations under the patent cross-license agreement are canceled. In addition, the Court issued interlocutory judgments ordering, among other things: (1) that Micron B.V. transfer to the Qimonda estate the Inotera Shares still owned by it and pay to the Qimonda estate compensation in an amount to be specified for any Inotera Shares sold to third parties; and (2) that Micron B.V. pay the Qimonda estate as compensation an amount to be specified for benefits derived by it from ownership of the Inotera Shares. The interlocutory judgments have no immediate, enforceable effect on us, and, accordingly, we expect to be able to continue to operate with full control of the Inotera Shares subject to further developments in the case. We have filed a notice of appeal, and the parties have submitted briefs to the appeals court. We are unable to predict the outcome of the matter and therefore cannot estimate the range of possible loss. The final resolution of this lawsuit could result in the loss of the Inotera Shares or monetary damages, unspecified damages based on the benefits derived by Micron B.V. from the ownership of the Inotera Shares, and/or the termination of the patent cross-license, which could have a material adverse effect on our business, results of operation, or financial condition. 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.

Temporary Equity [Abstract]
Redeemable Convertible Notes	Redeemable Convertible Notes Under the terms of the indentures governing the 2033 Notes, upon conversion, we would be required to pay cash equal to the lesser of (1) the aggregate principal amount or (2) the conversion value of the notes being converted. To the extent the conversion value exceeds the principal amount, we could pay cash, shares of common stock, or a combination thereof, at our option, for the amount of such excess. The closing price of our common stock met the thresholds for conversion for the calendar quarter ended March 31, 2017; therefore, the 2033 Notes were convertible by the holders as of June 1, 2017. As a result, the 2033 Notes were classified as current debt and the aggregate difference between the principal amount and the carrying value of $25 million was classified as redeemable convertible notes in the accompanying consolidated balance sheet as of June 1, 2017. The closing price of our common stock did not meet the thresholds for the calendar quarter ended June 30, 2016; therefore, the 2033 Notes were not convertible by the holders as of September 1, 2016. Therefore, as of September 1, 2016 , the 2033 Notes had been classified as noncurrent debt and the aggregate difference between the principal amount and the carrying value had been classified as additional capital.

Equity [Abstract]
Equity	Equity Micron Shareholders' Equity Treasury Stock : In connection with the Inotera Acquisition, in the second quarter of 2017, we sold 58 million shares of our common stock to Nanya for $986 million in cash, of which 54 million shares were issued from treasury stock. As a result, in the second quarter of 2017, treasury stock decreased by $1.03 billion , while retained earnings decreased by $104 million for the difference between the carrying value of the treasury stock and its $925 million fair value. Outstanding Capped Calls : Our capped calls are intended to reduce the effect of potential dilution from our convertible notes and provide for our receipt of cash or shares, at our election, from our counterparties if the trading price of our stock is above strike prices on the expiration dates. As of June 1, 2017 , the dollar value of cash or shares that we would receive from our outstanding capped calls upon their expiration dates range from $0 , if the trading price of our stock is below strike prices for all capped calls at expiration, to $527 million , if the trading price of our stock is at or above the cap prices for all capped calls. Expiration of Capped Calls : In the third quarter of 2017, we cash-settled a portion of our 2032C and 2032D Capped Calls and received $125 million , based on the volume-weighted trading stock prices at the expiration dates. In the second quarter of 2017, we share-settled a portion of our 2032C and 2032D Capped Calls and received 4 million shares of our stock, equal to a value of $67 million , based on the volume-weighted trading stock prices at the expiration dates. The shares received were recorded as treasury stock. Shareholder Rights Agreement : On January 18, 2017, our shareholders approved a Section 382 Rights Agreement (the "Rights Agreement"), under which our shareholders of record as of the close of business on August 1, 2016 received one right for each share of common stock outstanding, which entitles shareholders to purchase additional shares of our common stock at a significant discount in the event of an ownership change. The Rights Agreement is intended to avoid an ownership change, as defined by Section 382 of the Internal Revenue Code of 1986, as amended, and thereby preserve our current ability to utilize certain net operating loss and credit carryforwards. Noncontrolling Interests in Subsidiaries As of June 1, 2017 September 1, 2016 Noncontrolling Interest Balance Noncontrolling Interest Percentage Noncontrolling Interest Balance Noncontrolling Interest Percentage IMFT $ 832 49 % $ 832 49 % Other 16 Various 16 Various $ 848 $ 848 IMFT : Since IMFT's inception in 2006, we have owned 51% of IMFT, a joint venture between us and Intel that manufactures NAND and 3D XPoint memory products exclusively for the members. The members share the output of IMFT generally in proportion to their investment. IMFT is governed by a Board of Managers for which the number of managers appointed by each member varies based on the members' respective ownership interests. The IMFT joint venture agreement extends through 2024 and includes certain buy-sell rights. Through December 2018, Intel can put to us, and from January 2019 through December 2021, we can call from Intel, Intel's interest in IMFT, in either case, for an amount equal to the noncontrolling interest balance attributable to Intel at such time either member exercises its right. If Intel exercises its put right, we can elect to set the closing date of the transaction to be any time within two years following such election by Intel and can elect to receive financing of the purchase price from Intel for one to two years from the closing date. Creditors of IMFT have recourse only to IMFT's assets and do not have recourse to any other of our assets. In the third quarter of 2016, IMFT distributed $36 million and $34 million of cash to us and Intel, respectively, and in first nine months of 2016, we and Intel contributed $38 million and $37 million , respectively, to IMFT. IMFT manufactures memory products using designs and technology we develop with Intel. We generally share with Intel the costs of product design and process development activities for NAND and 3D XPoint memory at IMFT and our other facilities. Our R&D expenses were reduced by reimbursements from Intel of $47 million and $162 million for the third quarter and first nine months of 2017 , respectively, and $54 million and $153 million for the third quarter and first nine months of 2016 , respectively. Non-Trade sales primarily consists of NAND and 3D XPoint products manufactured and sold to Intel through IMFT at long-term negotiated prices approximating cost and were $138 million and $419 million for the third quarter and first nine months of 2017 , respectively, and $120 million and $372 million for the third quarter and first nine months of 2016 , respectively. The following table presents the assets and liabilities of IMFT included in our consolidated balance sheets: As of June 1, September 1, Assets Cash and equivalents $ 113 $ 98 Receivables 84 89 Inventories 120 68 Other current assets 4 6 Total current assets 321 261 Property, plant, and equipment, net 1,748 1,792 Other noncurrent assets 49 50 Total assets $ 2,118 $ 2,103 Liabilities Accounts payable and accrued expenses $ 215 $ 175 Deferred income 6 7 Current debt 19 16 Total current liabilities 240 198 Long-term debt 80 66 Other noncurrent liabilities 89 94 Total liabilities $ 409 $ 358 Amounts exclude intercompany balances that were eliminated in our consolidated balance sheets. Restrictions on Net Assets As a result of the corporate reorganization proceedings the MMJ Companies initiated in March 2012, and for so long as such proceedings continue, the MMJ Group is subject to certain restrictions on dividends, loans, and advances. In addition, the 2021 MSTW Term Loan contains covenants that limit or restrict the ability of MSTW and/or MTTW to distribute cash dividends. Also, our ability to access the cash and other assets of IMFT through dividends, loans, or advances, including to finance our other operations, is limited and is subject to agreement by Intel. As a result, our total restricted net assets (excluding intercompany balances and noncontrolling interests) as of June 1, 2017 were $3.48 billion for the MMJ Group, $2.55 billion for MSTW and MTTW, and $877 million for IMFT. As of June 1, 2017 , the MMJ Group held cash and equivalents of $595 million , MSTW and MTTW held $261 million , and IMFT held $113 million .

Fair Value Measurements	Fair Value Measurements All of our marketable debt and equity investments (excluding equity method investments) were classified as available-for-sale and carried at fair value. 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 (excluding the carrying value of the equity and mezzanine equity components of our convertible notes) were as follows: As of June 1, 2017 September 1, 2016 Fair Value Carrying Value Fair Value Carrying Value Notes and MMJ creditor installment payments $ 9,307 $ 8,895 $ 7,257 $ 7,050 Convertible notes 3,747 1,479 2,408 1,454 The fair values of our convertible notes were determined based on inputs that were observable in the market or that could be derived from, or corroborated with, observable market data, including the trading price of our convertible notes when available, our stock price, and interest rates based on similar debt issued by parties with credit ratings similar to ours (Level 2). The fair values of our other debt instruments were estimated based on discounted cash flows using inputs that were observable in the market or that could be derived from, or corroborated with, observable market data, including the trading price of our notes, when available, and interest rates based on similar debt issued by parties with credit ratings similar to ours (Level 2).

Derivative Instrument Detail [Abstract]
Derivative Instruments	Derivative Instruments We use derivative instruments to manage our exposure to changes in currency exchange rates from our monetary assets and liabilities denominated in currencies other than the U.S. dollar. We do not use derivative instruments for speculative purpose. Derivative Instruments without Hedge Accounting Designation Currency Derivatives : To hedge our exposures of monetary assets and liabilities to changes in currency exchange rates, we generally utilize a rolling hedge strategy with currency forward contracts that mature within nine months. In addition, to mitigate the risk of the yen strengthening against the U.S. dollar on our MMJ creditor installment payments due in December 2017 and 2018, we entered into forward contracts to purchase 18 billion yen in December 2017 and 28 billion yen in December 2018. At the end of each reporting period, monetary assets and liabilities denominated in currencies other than the U.S. dollar are remeasured into 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). Total notional amounts and gross fair values for derivative instruments without hedge accounting designation were as follows: Notional Amount (in U.S. Dollars) Fair Value Current Assets (1) Current Liabilities (2) As of June 1, 2017 New Taiwan dollar $ 3,083 $ 49 $ — Yen 1,177 4 (1 ) Singapore dollar 389 1 — Euro 193 1 — Other 45 — — $ 4,887 $ 55 $ (1 ) As of September 1, 2016 Yen $ 1,668 $ — $ (10 ) Singapore dollar 206 — — Euro 93 — — Other 85 — (1 ) $ 2,052 $ — $ (11 ) (1) Included in receivables – other. (2) Included in accounts payable and accrued expenses – other. 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). For derivative instruments without hedge accounting designation, we recognized net gains of $70 million and net losses of $47 million for the third quarter and first nine months of 2017 , respectively, and net gains of $42 million and $113 million for the third quarter and first nine months of 2016 , respectively. Derivative Instruments with Cash Flow Hedge Accounting Designation Currency Derivatives : We utilize currency forward contracts that generally mature within 12 months to hedge our exposure to changes in cash flows from changes in currency exchange rates for certain capital expenditures. Currency forward contracts are measured at fair value based on market-based observable inputs including currency exchange spot and forward rates, interest rates, and credit-risk spreads (Level 2). For derivative instruments designated as cash flow hedges, the effective portion of the realized and unrealized gain or loss on the derivatives is included as a component of accumulated other comprehensive income (loss). Amounts in accumulated other comprehensive income (loss) are reclassified into earnings in the same line items and in the same periods in which the underlying transactions affect earnings. The ineffective and excluded portion of the realized and unrealized gain or loss is included in other non-operating income (expense). Total notional amounts and gross fair values for derivative instruments with cash flow hedge accounting designation were as follows: Notional Amount (in U.S. Dollars) Fair Value Current Assets (1) Current Liabilities (2) As of June 1, 2017 Euro $ 129 $ 5 $ — Yen 86 1 (1 ) $ 215 $ 6 $ (1 ) As of September 1, 2016 Euro $ 65 $ — $ (1 ) Yen 107 2 (1 ) $ 172 $ 2 $ (2 ) (1) Included in receivables – other. (2) Included in accounts payable and accrued expenses – other. We recognized a gain in accumulated other comprehensive income (loss) from the effective portion of cash flow hedges of $6 million in the third quarter and a loss of $3 million in the first nine months of 2017 , and gains of $4 million and $5 million in the third quarter and first nine months of 2016 , respectively. Neither the ineffective portions of cash flow hedges recognized in other non-operating income (expense) nor amounts reclassified from accumulated other comprehensive income (loss) to earnings were material in the third quarters and first nine months 2017 and 2016 . The amounts from cash flow hedges included in accumulated other comprehensive income (loss) that are expected to be reclassified into earnings in the next 12 months are not material.

The 2016 Restructuring Plan includes the elimination of certain projects and programs, the permanent closure of a number of open headcount requisitions, workforce reductions in certain areas of our business, and other non-headcount related spending reductions. As a result, we incurred charges of $33 million in the first nine months of 2017 and $58 million in the fourth quarter of 2016 and do not expect to incur additional material charges. As of September 1, 2016 , we had accrued liabilities of $24 million related to the 2016 Restructuring Plan, substantially all of which was paid in the first nine months of 2017. On April 14, 2017, we entered into an agreement to sell our assembly and test facility located in Akita, Japan and our 40% ownership interest in Tera Probe, for aggregate consideration of $60 million , substantially all in cash, subject to changes in working capital. We completed the sale of our interest in Tera Probe in the third quarter of 2017 and expect to close the sale of the Akita facility in the fourth quarter of 2017. We recognized a loss of $11 million in the third quarter of 2017 for this transaction and do not expect to incur additional material charges.

Income Taxes	Income Taxes Our income tax (provision) benefit consisted of the following: Quarter ended Nine months ended June 1, June 2, June 1, June 2, Utilization of and other changes in net deferred tax assets of MMJ, MMT, and Inotera $ (31 ) $ (71 ) $ (52 ) $ (103 ) U.S. valuation allowance release resulting from business acquisition — — — 41 Other income tax (provision) benefit, primarily other non-U.S. operations (61 ) 56 (109 ) 46 $ (92 ) $ (15 ) $ (161 ) $ (16 ) Other income tax (provision) benefit in the table above for the third quarter and first nine months of 2016 included tax benefits of $52 million and $58 million , respectively, related to the favorable resolution of certain prior year tax matters, which were previously reserved as uncertain tax positions. We have a full valuation allowance for our net deferred tax assets associated with our U.S. operations. The amount of the deferred tax assets considered realizable could be adjusted if significant positive evidence increases. Income taxes on U.S. operations in the third quarters and first nine months of 2017 and 2016 were substantially offset by changes in the valuation allowance. As of the date of the Inotera Acquisition, Inotera's net operating loss carryforwards were $654 million , which expire on various dates through 2022. In connection with the Inotera Acquisition, we assumed $54 million of uncertain tax positions, of which $26 million was recorded in purchase accounting as a reduction to deferred tax assets. The amounts recorded in purchase accounting primarily related to the surtax treatment of certain purchase accounting adjustments. During the second quarter of 2017, $21 million of the uncertain tax positions assumed in the Inotera Acquisition reached effective settlement with no impact to tax expense or purchase accounting. Although the timing of final resolution is uncertain, the estimated potential reduction in the Inotera unrecognized tax benefits in the next 12 months ranges from $0 to $36 million , including interest and penalties. We operate in a number of tax jurisdictions, including Singapore and Taiwan, where our earnings are indefinitely reinvested and are taxed at lower effective tax rates than the U.S. statutory rate and in a number of locations outside the U.S., including Singapore, where we have tax incentive arrangements that are conditional, in part, upon meeting certain business operations and employment thresholds. The effect of tax incentive arrangements, which expire in whole or in part at various dates through 2030, reduced our tax provision for the third quarter and first nine months of 2017 by $250 million (benefitting our diluted earnings per share by $0.21 ) and $422 million ( $0.37 per diluted share), respectively, and were not material for the third quarter or first nine months of 2016 .

Segment Reporting [Abstract]
Segment Information	Segment Information Segment information reported herein is consistent with how it is reviewed and evaluated by our chief operating decision maker. We have the following four business units, which are our reportable segments: Compute and Networking Business Unit ("CNBU") : Includes memory products sold into compute, networking, graphics, and cloud server markets. Storage Business Unit ("SBU") : Includes memory products sold into enterprise, client, cloud, and removable storage markets. SBU also includes products sold to Intel through our IMFT joint venture. Mobile Business Unit ("MBU") : Includes memory products sold into smartphone, tablet, and other mobile-device markets. Embedded Business Unit ("EBU") : Includes memory products sold into automotive, industrial, connected home, and consumer electronics markets. Certain operating expenses directly associated with the activities of a specific segment are charged to that segment. Other indirect operating expenses (income) are generally allocated to segments based on their respective percentage of cost of goods sold or forecasted wafer production. In the first quarter of 2017, we revised the measure of segment profitability reviewed by our chief operating decision maker and, as a result, certain items are no longer allocated to our business units. Comparative periods have been revised to reflect these changes. Items not allocated are identified in the table below. We do not identify or report internally our assets (other than goodwill) or capital expenditures by segment, nor do we allocate gains and losses from equity method investments, interest, other non-operating income or expense items, or taxes to segments.

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

The closing price of our common stock also exceeded the thresholds for the calendar quarter ended June 30, 2017; therefore, these notes are convertible by the holders through September 30, 2017. The 2033 Notes were classified as current as of June 1, 2017 because the terms of these notes require us to pay cash for the principal amount of any converted notes and holders of these notes had the right to convert their notes as of that date. In addition, the holders of the 2033E Notes can require us to repurchase for cash all or a portion of the 2033E Notes on February 15, 2018.

[1]	The maturities of long-term marketable investments range from one to four years.
[2]	The fair value of Level 1 securities is measured based on quoted prices in active markets for identical assets.
[3]	The fair value of Level 2 securities is measured using information obtained from pricing services, which obtain quoted market prices for similar instruments, non-binding market consensus prices that are corroborated by observable market data, or various other methodologies, to determine the appropriate value at the measurement date. We perform supplemental analysis to validate information obtained from these pricing services. No adjustments were made to such pricing information as of June 1, 2017.

[1]	Since the closing price of our common stock exceeded 130% of the conversion price per share for at least 20 trading days in the 30 trading day period ended on March 31, 2017, these notes are convertible by the holders through the calendar quarter ending June 30, 2017. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended June 30, 2017; therefore, these notes are convertible by the holders through September 30, 2017. The 2033 Notes were classified as current as of June 1, 2017 because the terms of these notes require us to pay cash for the principal amount of any converted notes and holders of these notes had the right to convert their notes as of that date. In addition, the holders of the 2033E Notes can require us to repurchase for cash all or a portion of the 2033E Notes on February 15, 2018.
