Accounting Policies [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 (“U.S. GAAP”) consistent in all material respects with those applied in our Annual Report on Form 10-K for the year ended September 2, 2021.
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 years 2022 and 2021 each contain 52 weeks. All period references are to our fiscal periods unless otherwise indicated.

Disclosure of accounting policy for determining an entity's fiscal year or other fiscal period. This disclosure may include identification of the fiscal period end-date, the length of the fiscal period, any reporting period lag between the entity and its subsidiaries, or equity investees. If a reporting lag exists, the closing date of the entity having a different period end is generally noted, along with an explanation of the necessity for using different closing dates. Any intervening events that materially affect the entity's financial position or results of operations are generally also disclosed.
