Re: Registration Statement on Form S-8

Ladies and Gentlemen:

At your request, we are rendering this opinion in connection with the Registration Statement on Form S-8 to be filed by Micron Technology, Inc., a Delaware corporation (the “Company”), with the U.S. Securities and Exchange Commission (the “SEC”) on or about August 8, 2023 (the “Registration Statement”) for the proposed issuance of up to (a) 50,000,000 additional shares of common stock, $0.10 par value per share, of the Company (the “Additional Shares”), pursuant to the Micron Technology, Inc. Amended and Restated 2007 Equity Incentive Plan (the “Equity Plan”), and (b) $85,000,000 of deferred compensation obligations of the Company (the “Obligations”) pursuant to the Micron Technology, Inc. Deferred Compensation Plan (the “Deferred Compensation Plan”).

We have examined and relied, to the extent we deem proper, on certificates of the Company as to factual matters, and on the originals or copies certified or otherwise identified to our satisfaction, of all such corporate records of the Company and such other instruments, documents, and records that we have deemed relevant and necessary for the basis of our opinion hereinafter expressed. In such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies, and the truth, accuracy and completeness of the information, representations and warranties contained in the records, documents, instruments and certificates we have reviewed.

Based on such examination, we are of the opinion that following the filing of the Registration Statement:

(1) the Additional Shares to be issued by the Company pursuant to the Equity Plan are validly authorized and, when issued in accordance with the terms of the Equity Plan, will be legally issued, fully paid and non-assessable; and

(2) the Obligations, when issued in accordance with the terms of the Deferred Compensation Plan, will be legally valid and binding obligations of the Company, enforceable in accordance with their terms.
