Accounting Policies [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.

Variable Interest Entities

Variable Interest Entities	6 Months Ended
	Mar. 01, 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 therewith, we had capital lease obligations and net property, plant, and equipment of $78 million and $74 million , respectively, as of March 1, 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. 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 17% and 19% of our consolidated revenue for the second quarter and first six months of 2018 , respectively, and 20% and 22% of our consolidated revenue for the second quarter and first six 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 March 1, 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 March 1, 2018 , there were no available-for-sale securities that had been in a loss position for longer than 12 months.

The 2033 Notes were classified as current 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 the dates presented. (2) Amounts as of March 1, 2018 include $178 million and $129 million for the settlement obligation (principal and amounts in excess of principal) of 2033E Notes and 2033F Notes, respectively, that had been converted but not settled. Amounts as of August 31, 2017 include $88 million for the settlement obligation (principal and amounts in excess of principal) of 2033E Notes that had been converted but not settled. Debt Repurchases and Conversions During the first six months of 2018 , we repurchased or settled as a result of conversion an aggregate of $2.42 billion principal amount of our debt. 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 repurchases and conversions of our debt in the first six months of 2018: Six months ended March 1, 2018 Decrease in Principal Increase (Decrease) in Carrying Value Decrease in Cash Decrease in Equity Gain (Loss) Repurchases 2023 Notes $ (1,000 ) $ (991 ) $ (1,046 ) $ — $ (55 ) 2023 Secured Notes (1,250 ) (1,238 ) (1,373 ) — (135 ) Settled Conversions 2032C Notes (52 ) (49 ) (240 ) (195 ) 4 2033E Notes (1) (113 ) (143 ) (249 ) (97 ) (9 ) 2033F Notes (5 ) (5 ) (22 ) (17 ) — Conversions not settled 2033E Notes (2) — 137 — (124 ) (13 ) 2033F Notes (2) — 101 — (91 ) (10 ) $ (2,420 ) $ (2,188 ) $ (2,930 ) $ (524 ) $ (218 ) (1) Settlement included 4 million shares of our treasury stock in addition to cash. (2) As of March 1, 2018, $41 million in principal amount of the 2033E Notes and $30 million in principal amount of the 2033F Notes had converted but not settled. These notes will settle in cash in the third quarter of 2018. IMFT Member Debt In November 2017 and December 2017, Intel provided debt financing ("IMFT Member Debt") of $150 million and $500 million , respectively, to IMFT pursuant to the terms of the IMFT joint venture agreement. IMFT Member Debt bears no interest, matures upon the completion of the auction and the 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, 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 March 1, 2018 , the 2022 Term Loan B bears interest at LIBOR plus 2.00% . Convertible Senior Notes As of March 1, 2018 , the trading price of our common stock was higher than the initial conversion prices of our convertibles notes. As a result, the conversion values for these notes exceeded the principal amounts by $3.18 billion as of March 1, 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, 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 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. The complaint alleges that MXA and Micron Semiconductor (Shanghai) Co., Ltd. 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, to stop manufacturing, using, selling, and offering for sale the accused products, 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. The complaint alleges that MXA and Micron Semiconductor (Shanghai) Co., Ltd. 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, to stop manufacturing, using, selling, and offering for sale the accused products, and to pay damages of 90 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 March 1, 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. 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 [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 March 1, 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 $214 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 six months of 2018, we share-settled portions of our capped calls upon expiration, and received 7 million shares (equal to a value of $313 million ) based on the volume-weighted trading stock prices at the expiration dates. Shares received were recorded as treasury stock. Noncontrolling Interests in Subsidiaries As of March 1, 2018 August 31, 2017 Noncontrolling Interest Balance Noncontrolling Interest Percentage Noncontrolling Interest Balance Noncontrolling Interest 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 $115 million and $227 million for the second quarter and first six months of 2018 , respectively, and $142 million and $252 million for the second quarter and first six 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, at Intel's choice, between 50% and 100% of Intel's immediately preceding six -month period pre-closing volumes of IMFT products for the first six -month period following the closing and, at Intel's choice, between 0% and 100% 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 March 1, August 31, Assets Cash and equivalents $ 317 $ 87 Receivables 87 81 Inventories 99 128 Other current assets 5 7 Total current assets 508 303 Property, plant, and equipment, net 2,496 1,852 Other noncurrent assets 43 49 Total assets $ 3,047 $ 2,204 Liabilities Accounts payable and accrued expenses $ 472 $ 299 Deferred income 10 6 Current debt 19 19 Total current liabilities 501 324 Long-term debt 715 75 Other noncurrent liabilities 79 88 Total liabilities $ 1,295 $ 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 March 1, 2018 were $3.86 billion for the MMJ Group, $2.54 billion for MSTW and MTTW, and $900 million for IMFT.

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 March 1, 2018 August 31, 2017 Fair Value Carrying Value Fair Value Carrying Value Notes and MMJ Creditor Payments $ 6,792 $ 6,686 $ 8,793 $ 8,423 Convertible notes 4,922 1,580 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.

(2) Included in receivables – other. (3) Included in accounts payable and accrued expenses – other for forward contracts and in current debt for convertible notes settlement obligations. (4) Included in other noncurrent assets. 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 to hedge our exposure to changes in cash flows 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 gain or loss on the 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 gains in accumulated other comprehensive income from the effective portion of cash flow hedges of $21 million and $17 million for the second quarter and first six months of 2018 , respectively, and losses of $9 million in the first six months of 2017 . Neither the amount excluded from hedge effectiveness nor the reclassifications from accumulated other comprehensive income to earnings were material in the second quarters or first six 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 to hedge our exposure to certain changes in fair values 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 of the fair value of the undiscounted spot rate of the forward contract. The change in fair value of the hedge instrument attributed to changes in the undiscounted spot rate is recognized in other non-operating income (expense). The time value associated with the hedge instrument is excluded from the assessment of the effectiveness of the hedge and is recognized on a straight-line basis over the life of the hedge to other non-operating income (expense). Amounts recorded to other comprehensive income (loss) for the second quarter of 2018 were not material. The effects of fair value hedges on our consolidated statements of operations were as follows: Quarter ended March 1, 2018 Other Non-Operating Income (Expense) Gain (loss) on remeasurement of hedged assets and liabilities $ (56 ) Gain (loss) on derivatives designated as hedging instruments 56 Amortization of amounts excluded from hedge effectiveness (19 ) $ (19 ) Derivative Instruments without Hedge Accounting Designation Currency Derivatives : Except for certain asset 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 to 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 due to changes in currency exchange rates are included in other non-operating income (expense). For derivative instruments without hedge accounting designation, we recognized gains of $50 million and $52 million for the second quarter and first six months of 2018 , respectively, and gains of $61 million and losses of $117 million for the second quarter and first six months of 2017 , respectively. Convertible Notes Settlement Obligations : For settlement obligations associated with our convertible notes that become derivative debt liabilities 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 of our convertible note settlement obligations were based on the volume-weighted-average stock price (Level 2). (See "Debt" note.) We recognized losses of $20 million and $24 million for the second quarter and first six months of 2018, respectively, for the changes in fair value of the derivative settlement obligations in other non-operating income (expense), net.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the U.S. government 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's 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 for the second quarter of fiscal year 2018 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 Six months ended March 1, 2018 March 2, 2017 March 1, 2018 March 2, 2017 Provisional estimate for the Repatriation Tax on substantially all of our accumulated foreign earnings, net of adjustments related to uncertain tax positions $ (1,335 ) $ — $ (1,335 ) $ — Remeasurement of deferred tax assets and liabilities reflecting the lower U.S. corporate tax rates (133 ) — (133 ) — Provisional estimate for the release of the valuation allowance on the net deferred tax assets of our U.S. operations 1,337 — 1,337 — Utilization of and other changes in net deferred tax assets of MMJ, MMT, and MTTW (17 ) (8 ) (43 ) (21 ) Other income tax (provision) benefit 5 (30 ) (83 ) (48 ) $ (143 ) $ (38 ) $ (257 ) $ (69 ) 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 may determine the portion of the accumulated foreign earnings taxed at an effective rate of 15.5% or 8% . As a result, the Repatriation Tax may change as amounts are finalized. The U.S. Department of Treasury has issued interpretive guidance regarding the Repatriation Tax and we expect that they 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. As of March 1, 2018, we had gross unrecognized income tax benefits of $209 million , of which $196 million would affect our effective tax rate in the future, if recognized. The Tax Act reduced unrecognized tax benefits by $123 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 $436 million (benefitting our diluted earnings per share by $0.35 ) and $827 million ( $0.67 per diluted share) for the second quarter and first six months of 2018 , respectively, and $132 million ( $0.11 per diluted share) and $172 million ( $0.15 per diluted share), for the second quarter and first six months of 2017 , respectively.

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

[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 December 31, 2017, these notes are convertible by the holders through the calendar quarter ended March 31, 2018. The 2033 Notes were classified as current 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 the dates presented.
[2]	Amounts as of March 1, 2018 include $178 million and $129 million for the settlement obligation (principal and amounts in excess of principal) of 2033E Notes and 2033F Notes, respectively, that had been converted but not settled.
