Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 29, 2019, except for changes related to recently adopted accounting standards. See “Recently Adopted Accounting Standards” note.
Comparability of Prior Year Financial Data	Prior year information is presented in accordance with the accounting guidance in effect during that period and has not been recast for recently adopted accounting standards.
Reclassifications	Certain reclassifications have been made to prior period amounts to conform to current period presentation.
Fiscal Period	Our fiscal year is the 52 or 53-week period ending on the Thursday closest to August 31. Fiscal year 2020 contains 53 weeks and the fourth quarter of 2020 will contain 14 weeks. All period references are to our fiscal periods unless otherwise indicated.

Disclosure of accounting policy for basis of accounting, or basis of presentation, used to prepare the financial statements (for example, US Generally Accepted Accounting Principles, Other Comprehensive Basis of Accounting, IFRS).
