Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts of Micron and our consolidated subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America consistent in all material respects with those applied in our Annual Report on Form 10-K for the year ended August 31, 2017. In the opinion of our management, the accompanying unaudited consolidated financial statements contain all necessary adjustments, consisting of a normal recurring nature, to fairly state the financial information set forth herein. Certain reclassifications have been made to prior period amounts to conform to current period presentation. Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Fiscal years 2018 and 2017 each contain 52 weeks. All period references are to our fiscal periods unless otherwise indicated. These interim financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended August 31, 2017.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Our significant accounting policies include those described in our Annual Report on Form 10-K for the year ended August 31, 2017 as well as the policy below. Government Incentives: We receive incentives from governmental entities related to expenses, assets, and other activities. Our government incentives may require that we meet or maintain specified spending levels and other operational metrics and may be subject to reimbursement if such conditions are not met or maintained. Government incentives are recorded in the financial statements in accordance with their purpose: as a reduction of expenses, a reduction of asset costs, or other income. Incentives related to specific operating activities are offset against the related expense in the period the expense is incurred. Incentives related to the acquisition or construction of fixed assets are recognized as a reduction in the carrying amounts of the related assets and reduce depreciation expense over the useful lives of the assets. Other incentives are recognized as other operating income. Government incentives received prior to being earned are recognized in current or noncurrent deferred income, whereas government incentives earned prior to being received are recognized in current or noncurrent receivables. Cash received from government incentives related to operating expenses are included as an operating activity in the statement of cash flows, whereas incentives related to the acquisition of property, plant, and equipment are included as an investing activity.

Variable Interest Entities

Variable Interest Entities	9 Months Ended
	May 31, 2018
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 VIE 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. In connection with our assembly services with PTI, we had capital lease obligations and net property, plant, and equipment of $72 million and $69 million , respectively, as of May 31, 2018 , and $80 million and $76 million , respectively, as of August 31, 2017 . 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. 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 Issued Accounting Standards	Recently Issued Accounting Standards In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 and requires modified retrospective adoption. We are evaluating the 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 with adoption permitted 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 in 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, with prospective adoption for amendments related to equity securities without readily determinable fair values. Our assets and liabilities subject to this standard are not material. 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 United States. 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. This ASU will be effective for us in the first quarter of 2019 and we expect to elect the modified retrospective adoption method. As a result of the adoption of this ASU, we expect to recognize revenue from sales of products to our distributors (which generally have agreements allowing rights of return or price protection) at the time control transfers to our distributors, which is generally earlier than recognizing revenue only upon resale by our distributors under existing revenue recognition guidance. Revenue recognized upon resale by our distributors under these arrangements was 19% of our consolidated revenue for the third quarter and first nine months of 2018 , and 19% and 21% of our consolidated revenue for the third quarter and first nine months of 2017 , respectively. On the date of initial application of this ASU, we will derecognize the deferred income on sales made to our distributors through a cumulative adjustment to retained earnings. We expect the revenue deferral, historically recognized in the following period, to be offset by the earlier recognition of revenue as described above as control of product transfers to our distributors. As a result of the adoption of this ASU, we expect to recognize interest expense from the financing component for contracts with advanced payments under which we transfer control of our products to our customers for periods extending beyond one year, although historically such arrangements would not have resulted in significant amounts of interest expense. As a result of the adoption of this ASU, we expect that revenue recognized under our current license agreements will not change materially.

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") and accounted for our ownership interest under the equity method. On December 6, 2016, we acquired the remaining 67% ownership interest in Inotera not owned by us (the "Inotera Acquisition") and began consolidating Inotera's operating results. Inotera manufactures DRAM products at its 300mm wafer fabrication facility in Taoyuan City, Taiwan, and previously sold such products exclusively to us through supply agreements, under which we purchased $504 million of DRAM products in the first quarter of 2017, based on a pricing formula that equally shared margin between Inotera and us. Pro Forma Financial Information The following 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 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.

(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 analyses to validate information obtained from these pricing services. No adjustments were made to the fair values indicated by such pricing information as of May 31, 2018 or August 31, 2017. (4) Restricted cash is included in other noncurrent assets and primarily represents balances related to the MMJ Creditor Payments and interest reserve balances related to the 2021 MSTW Term Loan. Gross realized gains and losses from sales of available-for-sale securities were not material for any period presented. As of May 31, 2018 , there were no available-for-sale securities that had been in a loss position for longer than 12 months.

Current debt as of May 31, 2018 included an aggregate of $553 million for the settlement obligation (including principal and amounts in excess of principal) for conversions of certain convertible notes that will settle in cash in the fourth quarter of 2018. Additionally, the closing price of our common stock also exceeded the thresholds for the calendar quarter ended June 30, 2018; therefore, these notes are convertible by the holders at any time through September 30, 2018. (2) The 2032C Notes were classified as current as of May 31, 2018 because the holders can require us to repurchase for cash all or a portion of the 2032C Notes on May 1, 2019. The carrying values in the table above as of May 31, 2018 include $4 million of principal amount of our 2033E Notes for which we announced we would redeem on June 15, 2018 and $553 million for the aggregate settlement obligation of certain convertible notes that had been converted but not settled. Additionally, in June 2018, we made an irrevocable election under the terms of the 2021 MSTW Term Loan to prepay principal of 25 billion New Taiwan dollars (equivalent to $836 million as of May 31, 2018) on July 6, 2018. These items had an aggregate carrying value of $1.39 billion as of May 31, 2018 that will settle in the fourth quarter of 2018 and reduce the carrying value of our debt. Debt Prepayments, Repurchases, and Conversions During the first nine months of 2018 , we prepaid, repurchased, and settled conversions of debt with an aggregate of $4.73 billion principal amount. When we receive a notice of conversion for any of our convertible notes and elect to settle in cash any amount of the conversion obligation in excess of the principal amount, the cash settlement obligations become derivative debt liabilities subject to mark-to-market accounting treatment based on the volume-weighted-average price of our common stock over a period of 20 consecutive trading days. Accordingly, at the date of our election to settle a conversion in cash, we reclassify the fair value of the equity component of the converted notes from additional capital to derivative debt liability within current debt in our consolidated balance sheet. The following table presents the effects of prepayments, repurchases, and conversions of debt in the first nine months of 2018: Nine months ended May 31, 2018 Decrease in Principal Increase (Decrease) in Carrying Value Decrease in Cash Decrease in Equity Gain (Loss) Prepayments and repurchases 2021 MSAC Term Loan $ (730 ) $ (727 ) $ (730 ) $ — $ (3 ) 2021 MSTW Term Loan (671 ) (668 ) (671 ) — (3 ) 2023 Notes (1,000 ) (991 ) (1,046 ) — (55 ) 2023 Secured Notes (1,250 ) (1,238 ) (1,373 ) — (135 ) 2024 Notes (550 ) (546 ) (572 ) — (25 ) 2026 Notes (129 ) (129 ) (139 ) — (11 ) 2033F Notes (66 ) (63 ) (316 ) (252 ) (1 ) Settled conversions 2032C Notes (52 ) (49 ) (240 ) (195 ) 4 2033E Notes (1) (161 ) (191 ) (491 ) (251 ) (49 ) 2033F Notes (119 ) (114 ) (575 ) (447 ) (14 ) Conversions not settled (2) 2032C Notes — 338 — (264 ) (74 ) 2032D Notes — 64 — (51 ) (13 ) 2033E Notes — 31 — (29 ) (3 ) 2033F Notes — 17 — (14 ) (3 ) 2043G Notes — 6 — (5 ) (1 ) $ (4,728 ) $ (4,260 ) $ (6,153 ) $ (1,508 ) $ (386 ) (1) Settlement included issuance of 4 million shares of our treasury stock in addition to payment of cash. (2) As of May 31, 2018, an aggregate of $101 million in principal amount of our convertible notes (with a carrying value of $553 million ) had converted but not settled. These notes will settle in cash in the fourth quarter of 2018. IMFT Member Debt In the first nine months of 2018, Intel provided debt financing ("IMFT Member Debt") of $969 million to IMFT pursuant to the terms of the IMFT joint venture agreement. IMFT Member Debt bears no interest, matures upon the completion of an auction and sale of assets of IMFT prior to the dissolution, liquidation, or other wind-up of IMFT, and is convertible, at the election of Intel, in whole or in part, into a capital contribution to IMFT. Additionally, to the extent IMFT distributes cash to its members under the terms of the IMFT joint venture agreement, Intel may, at its option, designate any portion of the distribution to be a repayment of the IMFT Member Debt. In the event Intel exercises its right to put its interest in IMFT to us, or if we exercise our right to call from Intel its interest in IMFT, Intel will transfer to Micron any IMFT Member Debt outstanding at the time of the closing of the put or call transaction. (See "Equity – Noncontrolling Interest in Subsidiaries – IMFT" note.) 2022 Senior Secured Term Loan B Repricing Amendment On October 26, 2017 and April 27, 2018, we amended our 2022 Term Loan B, substantially all of which was treated as a debt modification, to reduce the interest rate margins. As of May 31, 2018 , the 2022 Term Loan B bears interest at LIBOR plus 1.75% . Convertible Senior Notes As of May 31, 2018 , 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 $3.21 billion as of May 31, 2018 .

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 are 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 upon their intellectual property rights. On November 21, 2014, Elm 3DS Innovations, LLC ("Elm") filed a patent infringement action against Micron, Micron Semiconductor Products, Inc., and Micron Consumer Products Group, Inc. in the U.S. District Court for the District of Delaware. On March 27, 2015, Elm filed an amended complaint against the same entities. The amended complaint alleges that unspecified semiconductor products of ours that incorporate multiple stacked die infringe 13 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 alleged that a variety of our DRAM products infringed two U.S. patents and sought damages, injunctive relief, and other unspecified relief. On March 1, 2018, 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 March 19, 2018, Micron Semiconductor (Xi’an) Co., Ltd. ("MXA") was served with a patent infringement complaint filed by Fujian Jinhua Integrated Circuit Co., Ltd. ("Jinhua") in the Fuzhou Intermediate People’s Court in Fujian Province, China. On April 3, 2018, Micron Semiconductor (Shanghai) Co. Ltd. ("MSS") was served with the same complaint. The complaint alleges that MXA and MSS infringe a Chinese patent by manufacturing and selling certain Crucial DDR4 DRAM modules. The complaint seeks an order requiring the defendants to destroy inventory of the accused products and equipment for manufacturing the accused products in China, to stop manufacturing, using, selling, and offering for sale the accused products in China, and to pay damages of 98 million Chinese yuan plus court fees incurred. On March 21, 2018, MXA was served with a patent infringement complaint filed by United Microelectronics Corporation ("UMC") in the Fuzhou Intermediate People's Court in Fujian Province, China. On April 3, 2018, MSS was served with the same complaint. The complaint alleges that MXA and MSS infringe a Chinese patent by manufacturing and selling certain Crucial DDR4 DRAM modules. The complaint seeks an order requiring the defendants to destroy inventory of the accused products and equipment for manufacturing the accused products in China, to stop manufacturing, using, selling, and offering for sale the accused products in China, and to pay damages of 90 million Chinese yuan plus court fees incurred. On April 3, 2018, MSS was served with another patent infringement complaint filed by Jinhua and two additional complaints filed by UMC in the Fuzhou Intermediate People's Court in Fujian Province, China. The three additional complaints allege that MSS infringes three Chinese patents by manufacturing and selling certain Crucial MX300 SSDs and certain GDDR5 memory chips. The two complaints filed by UMC each seek an order requiring the defendant to destroy inventory of the accused products and equipment for manufacturing the accused products in China, to stop manufacturing, using, selling, and offering for sale the accused products in China, and to pay damages of 90 million Chinese yuan plus court fees incurred. The complaint filed by Jinhua seeks an order requiring the defendants to destroy inventory of the accused products and equipment for manufacturing the accused products in China, to stop manufacturing, using, selling, and offering for sale the accused products in China, and to pay damages of 98 million Chinese yuan plus court fees incurred. 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's 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 May 31, 2018 , 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 the Inotera 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 Micron B.V. 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 Micron B.V. 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 On December 5, 2017, Micron filed a complaint against UMC and Jinhua in the U.S. District Court for the Northern District of California. The complaint alleges that UMC and Jinhua violated the Defend Trade Secrets Act, the civil provisions of the Racketeer Influenced and Corrupt Organizations Act, and California's Uniform Trade Secrets Act by misappropriating Micron's trade secrets and other misconduct. Micron's complaint seeks damages, restitution, disgorgement of profits, injunctive relief, and other appropriate relief. On April 27, 2018, a purported class-action lawsuit was filed against Micron and other DRAM suppliers in the U.S. District Court for the Northern District of California asserting claims based on alleged price-fixing of DRAM products during the period from June 1, 2016 to February 1, 2018. Similar cases were subsequently filed in Canadian courts in Quebec, Montreal and Toronto, Ontario. The complaints seek treble monetary damages, costs, interest, attorneys' fees, and other injunctive and equitable relief. We are unable to predict the outcome of these matters and therefore cannot estimate the range of possible loss. The final resolution of these matters could result in significant liability and could have a material adverse effect on our business, results of operations, or financial condition. 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.

Equity

Equity [Abstract]
Equity	Equity Micron Shareholders' Equity Common Stock Issuance : In October 2017, we issued 34 million shares of our common stock for $41.00 per share in a public offering for proceeds of $1.36 billion , net of underwriting fees and other offering costs. Outstanding Capped Calls : In connection with certain of our convertible notes, we entered into capped call transactions, which are intended to reduce the effect of potential dilution. The capped calls provide for our receipt of cash or shares, at our election, from our counterparties if the trading price of our stock is above the strike prices on the expiration dates. As of May 31, 2018 , 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 the strike prices for all capped calls at expiration, to $98 million , if the trading price of our stock is at or above the cap prices for all capped calls. Settlement of the capped calls prior to the expiration dates may be for an amount less than the maximum value at expiration. Settlement of Capped Calls : During the first nine months of 2018, we share-settled portions of our capped calls upon expiration, and received 9 million shares (equal to a value of $429 million ) based on the volume-weighted trading stock prices at the expiration dates. Shares received were recorded as treasury stock. Common Stock Repurchase Authorization : In May 2018, we announced that our Board of Directors had authorized the discretionary repurchase of up to $10 billion of our outstanding common stock beginning in 2019. We may purchase shares on a discretionary basis through open-market purchases, block trades, privately-negotiated transactions, and/or derivative transactions, subject to market conditions and our ongoing determination of the best use of available cash. The repurchase authorization does not obligate us to acquire any common stock. Noncontrolling Interests in Subsidiaries As of May 31, 2018 August 31, 2017 Balance Percentage Balance Percentage IMFT $ 852 49 % $ 832 49 % Other 17 Various 17 Various $ 869 $ 849 IMFT : Since 2006, we have owned 51% of IMFT, a joint venture between us and Intel. 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. IMFT manufactures semiconductor products exclusively for its members under a long-term supply agreement at prices approximating cost. IMFT's capital requirements are generally determined based on an annual plan approved by the members, and capital contributions to IMFT are requested as needed. Capital requests are made to the members in proportion to their then-current ownership interest. Members may elect to not contribute their proportional share, and in such event, the contributing member may elect to contribute any amount of the remaining capital request, either in the form of an equity contribution or member debt financing. Under the supply agreement, the members have rights and obligations to the capacity of IMFT in proportion to their investment, including member debt financing. Any capital contribution or member debt financing results in a proportionate adjustment to the sharing of output on an eight -month lag. Members pay their proportionate share of fixed costs associated with IMFT's capacity. IMFT sales to Intel were $114 million and $341 million for the third quarter and first nine months of 2018 , respectively, and $123 million and $375 million for the third quarter and first nine months of 2017 , respectively. In the first quarter of 2018, IMFT discontinued production of NAND and subsequent to that time is entirely focused on 3D XPoint memory production. The IMFT joint venture agreement extends through 2024 and includes certain buy-sell rights. At any time 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 a price that approximates Intel's interest in the net book value of IMFT plus member debt at the time of the closing. If Intel exercises its put right, we can elect to set the closing date of the transaction any time between six months and two years following such election by Intel and we can elect to receive financing of the purchase price from Intel for one to two years from the closing date. If we exercise our call right, Intel can elect to set the closing date of the transaction to be any time between six months and one year following such election. Following the closing date resulting from exercise of either the put or the call, we will continue to supply to Intel for a period of one year between 50% and 100% , at Intel's choice, of Intel's immediately preceding six -month period pre-closing volumes of IMFT products for the first six -month period following the closing and between 0% and 100% , at Intel's choice, of Intel's first six -month period following the closing volumes of IMFT products for the second six -month period following the closing, at a margin that varies depending on whether the put or call was exercised. Creditors of IMFT have recourse only to IMFT's assets and do not have recourse to any other of our assets. The following table presents the assets and liabilities of IMFT included in our consolidated balance sheets: As of May 31, August 31, Assets Cash and equivalents $ 109 $ 87 Receivables 86 81 Inventories 119 128 Other current assets 6 7 Total current assets 320 303 Property, plant, and equipment, net 2,706 1,852 Other noncurrent assets 46 49 Total assets $ 3,072 $ 2,204 Liabilities Accounts payable and accrued expenses $ 200 $ 299 Deferred income 9 6 Current debt 20 19 Total current liabilities 229 324 Long-term debt 1,029 75 Other noncurrent liabilities 77 88 Total liabilities $ 1,335 $ 487 Amounts exclude intercompany balances that were eliminated in our consolidated balance sheets. Restrictions on Net Assets As a result of the corporate reorganization proceedings of MMJ, the 2021 MSTW Term Loan covenants, and the IMFT joint venture agreement, our total restricted net assets (excluding intercompany balances and noncontrolling interests) as of May 31, 2018 were $3.98 billion for the MMJ Group, $4.06 billion for MSTW and MTTW, and $885 million for IMFT.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements All of our marketable debt and equity 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 our outstanding debt instruments (excluding the carrying value of equity and mezzanine equity components of our convertible notes) were as follows: As of May 31, 2018 August 31, 2017 Fair Value Carrying Value Fair Value Carrying Value Notes and MMJ Creditor Payments $ 4,870 $ 4,808 $ 8,793 $ 8,423 Convertible notes 4,734 1,585 3,901 1,521 The fair values of our convertible notes were determined based on Level 2 inputs, 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. The fair values of our other debt instruments were estimated based on Level 2 inputs, including discounted cash flows, 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.

(4) Included in other noncurrent assets. (5) Notional amounts of convertible notes settlement obligations as of May 31, 2018 and August 31, 2017 were 10 million and 2 million shares of our common stock, respectively. Derivative Instruments with Hedge Accounting Designation We utilize currency forward contracts that generally mature within twelve months to hedge our exposure to changes in currency exchange rates. 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). Cash Flow Hedges : We utilize cash flow hedges for our exposure from changes in currency exchange rates for certain capital expenditures. For derivative instruments designated as cash flow hedges, the effective portion of the realized and unrealized gains or losses on derivatives is included as a component of accumulated other comprehensive income. Amounts in accumulated other comprehensive income are reclassified into earnings in the same line items and in the same periods in which the underlying transactions affect earnings. For the periods presented prior to the second quarter of 2018, the ineffective and excluded portion of the realized and unrealized gain or loss was included in other non-operating income (expense). As a result of adopting ASU 2017-12, beginning in the second quarter of 2018, such amounts are included in the same line item in which the underlying transactions affect earnings. We recognized losses in accumulated other comprehensive income from the effective portion of cash flow hedges of $23 million and $6 million for the third quarter and first nine months of 2018 , respectively, and gains of $6 million and losses of $3 million for the third quarter and first nine months of 2017 , respectively. Neither the amount excluded from hedge effectiveness nor the reclassifications from accumulated other comprehensive income to earnings were material in the third quarters or first nine months of 2018 and 2017 . The amounts from cash flow hedges included in accumulated other comprehensive income that are expected to be reclassified into earnings in the next 12 months were also not material. Fair Value Hedges : We utilize fair value hedges for our exposure from changes in currency exchange rates for certain monetary assets and liabilities. For derivative forward contracts designated as fair value hedges, hedge effectiveness is determined by the change in the fair value of the undiscounted spot rate of the forward contract. The changes in fair values of hedge instruments attributed to changes in undiscounted spot rates are recognized in other non-operating income (expense). The time value associated with hedge instruments is excluded from the assessment of the effectiveness of hedges and is recognized on a straight-line basis over the life of hedges to other non-operating income (expense). Amounts recorded to other comprehensive income (loss) for the third quarter and first nine months of 2018 were not material. The effects of fair value hedges on our consolidated statements of operations were as follows: Quarter ended Nine months ended May 31, 2018 May 31, 2018 Other Non-Operating Income (Expense) Gain (loss) on remeasurement of hedged assets and liabilities $ 28 $ (28 ) Gain (loss) on derivatives designated as hedging instruments (28 ) 28 Amortization of amounts excluded from hedge effectiveness (13 ) (32 ) $ (13 ) $ (32 ) Derivative Instruments without Hedge Accounting Designation Currency Derivatives : Except for certain assets and liabilities hedged using fair value hedges, we generally utilize a rolling hedge strategy with currency forward contracts that mature within nine months to hedge our exposures of monetary assets and liabilities from changes in currency exchange rates. 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). Realized and unrealized gains and losses on derivative instruments without hedge accounting designation as well as the changes in the underlying monetary assets and liabilities from changes in currency exchange rates are included in other non-operating income (expense). For derivative instruments without hedge accounting designation, we recognized losses of $52 million for the third quarter, which offset $52 million of gains recognized during the first six months of 2018 , and we recognized gains of $70 million and losses of $47 million for the third quarter and first nine months of 2017 , respectively. Convertible Note Settlement Obligations : For settlement obligations associated with our convertible notes subject to mark-to-market accounting treatment, the fair values of the underlying derivative settlement obligations were initially determined using the Black-Scholes option valuation model (Level 2), which requires inputs of stock price, expected stock-price volatility, estimated option life, risk-free interest rate, and dividend rate. The subsequent measurement amounts were based on the volume-weighted-average price of our common stock (Level 2). (See "Debt" note.) We recognized losses of $119 million and $143 million for the third quarter and first nine months of 2018, respectively, in other non-operating income (expense), net for the changes in fair value of the derivative settlement obligations.

Employee Stock Purchase Plan Our ESPP was approved by shareholders at our 2017 Annual Shareholder Meeting and will be offered to substantially all employees beginning in August 2018. The ESPP permits eligible employees to purchase shares of our common stock through payroll deductions of up to 10% of their eligible compensation, subject to certain limitations. The purchase price of the shares under the ESPP equals 85% of the lower of the fair market value of our common stock on either the first or last trading day of each six -month offering period.

As a result, we recognized a non-operating gain of $71 million in the second quarter of 2017.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the United States enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act") that lowers the U.S. corporate income tax rate from 35% to 21% and significantly affects how income from foreign operations is taxed in the United States. As a result of our fiscal year-end, our U.S. statutory federal rate will be 25.7% for 2018 (based on the 35% corporate rate through December 31, 2017 and 21% from that date through the end of fiscal year 2018) and 21% for subsequent years. The Tax Act imposes a one-time transition tax in 2018 on the higher of our accumulated foreign income, as determined as of November 2, 2017 or December 31, 2017 (the "Repatriation Tax"); provides a U.S. federal tax exemption on foreign earnings distributed to the United States; and, beginning in 2019, creates a new minimum tax on certain foreign earnings in excess of a deemed return on tangible assets (the "Foreign Minimum Tax"). The Tax Act allows us to elect to pay any Repatriation Tax due in eight annual interest-free payments in increasing amounts beginning in December 2018. In connection with the provisions of the Tax Act, we are continuing to evaluate whether to account for the Foreign Minimum Tax provisions that begin for us in 2019 as a period cost or in our measurement of deferred taxes. The Securities and Exchange Commission Staff Accounting Bulletin No. 118 ("SAB 118") allows the use of provisional amounts (reasonable estimates) if our analyses of the impacts of the Tax Act has not been completed when our financial statements are issued. Provisional amounts may be adjusted during a one-year measurement period as accounting for the income tax effects of the Tax Act are completed or as estimates are revised. In accordance with SAB 118, we recorded certain provisional estimates included in the table below. Although the provisional estimates are based on the best available interpretations of the Tax Act, the final impacts may differ from the estimates due to, among other things, the issuance of additional regulatory and legislative guidance related to the Tax Act. Our income tax (provision) benefit consisted of the following: Quarter ended Nine months ended May 31, 2018 June 1, 2017 May 31, 2018 June 1, 2017 Provisional estimate for the Repatriation Tax, net of adjustments related to uncertain tax positions $ 222 $ — $ (1,113 ) $ — Remeasurement of deferred tax assets and liabilities reflecting the lower U.S. corporate tax rates — — (133 ) — Provisional estimate for the release of the valuation allowance on the net deferred tax assets of our U.S. operations — — 1,337 — Utilization of and other changes in net deferred tax assets of MMJ, MMT, and MTTW (35 ) (31 ) (78 ) (52 ) Other income tax (provision) benefit (78 ) (61 ) (161 ) (109 ) $ 109 $ (92 ) $ (148 ) $ (161 ) As noted above, provisional estimates were recorded for the Repatriation Tax and the release of the valuation allowance on the net deferred tax assets of our U.S. operations. To determine the amount of the Repatriation Tax, we must determine the accumulated foreign earnings of our foreign subsidiaries and the amount of foreign income tax paid on such earnings. The provisional estimate of the Repatriation Tax is also based, in part, on the amount of cash and other specified assets anticipated to be held by our foreign subsidiaries as of August 30, 2018, the end of our fiscal year 2018, which will determine the portion of the accumulated foreign earnings taxed at an effective rate of 15.5% or 8% . The provisional estimate for the Repatriation Tax was revised in the third quarter of 2018, and may continue to be revised as amounts are finalized. The U.S. Department of Treasury has issued interpretive guidance regarding the Repatriation Tax and we expect that it will issue additional guidance. Based on the information available, we can reasonably estimate the Repatriation Tax and therefore recorded a provisional amount; however, we are continuing to gather additional information and analyze authoritative guidance to finalize the computation of the Repatriation Tax as well as the impacts on the valuation allowance release of the Repatriation Tax and the Tax Act. During the third quarter of 2018, we reassessed our capital structure, including our Board of Directors' authorization to repurchase up to $10 billion of our outstanding common stock beginning in 2019, the future cash needs of our global operations, and the effects of the Tax Act. As a result of this reassessment, we deemed a portion of our foreign earnings to be no longer indefinitely invested. As a result of the Repatriation Tax, substantially all of our accumulated foreign earnings prior to December 31, 2017 were subject to U.S. federal taxation. Although we have provided for U.S. federal income tax on these earnings, the repatriation to the United States of all or a portion of these earnings would be subject to foreign and state income tax. As a result, in the third quarter of 2018, we recognized income tax provision of $68 million for deferred tax liabilities associated with our reassessment of our indefinitely reinvested earnings, which was substantially offset by a reduction in valuation allowances. As of May 31, 2018 , we had gross unrecognized income tax benefits of $202 million , of which $196 million would affect our effective tax rate in the future, if recognized. In 2018, the Tax Act reduced unrecognized tax benefits by $126 million . The amount accrued for interest and penalties related to uncertain tax positions was not material for any period presented. We operate in a number of tax jurisdictions outside the United States, 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 by $527 million (benefitting our diluted earnings per share by $0.43 ) and $1.35 billion ( $1.10 per diluted share) for the third quarter and first nine months of 2018 , respectively, and $250 million ( $0.21 per diluted share) and $422 million ( $0.37 per diluted share), for the third quarter and first nine months of 2017 , respectively.

Government Incentives	Government Incentives: We receive incentives from governmental entities related to expenses, assets, and other activities. Our government incentives may require that we meet or maintain specified spending levels and other operational metrics and may be subject to reimbursement if such conditions are not met or maintained. Government incentives are recorded in the financial statements in accordance with their purpose: as a reduction of expenses, a reduction of asset costs, or other income. Incentives related to specific operating activities are offset against the related expense in the period the expense is incurred. Incentives related to the acquisition or construction of fixed assets are recognized as a reduction in the carrying amounts of the related assets and reduce depreciation expense over the useful lives of the assets. Other incentives are recognized as other operating income. Government incentives received prior to being earned are recognized in current or noncurrent deferred income, whereas government incentives earned prior to being received are recognized in current or noncurrent receivables. Cash received from government incentives related to operating expenses are included as an operating activity in the statement of cash flows, whereas incentives related to the acquisition of property, plant, and equipment are included as an investing activity.

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.

[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, 2018, these notes are convertible by the holders at any time through the calendar quarter ended June 30, 2018. Current debt as of May 31, 2018 included an aggregate of $553 million for the settlement obligation (including principal and amounts in excess of principal) for conversions of certain convertible notes that will settle in cash in the fourth quarter of 2018. Additionally, the closing price of our common stock also exceeded the thresholds for the calendar quarter ended June 30, 2018; therefore, these notes are convertible by the holders at any time through September 30, 2018.
[2]	The 2032C Notes were classified as current as of May 31, 2018 because the holders can require us to repurchase for cash all or a portion of the 2032C Notes on May 1, 2019.
