Micron CEO Sanjay Mehrotra Announces $250 Billion Investment for Expanded Artificial Intelligence (AI) Memory Chip Development

Micron’s CEO Sanjay Mehrotra announced the company will invest more than $250 billion in U.S. factory expansions to scale AI memory development, targeting higher-volume high-bandwidth memory (HBM) and expanded DRAM output. The plan is intended to strengthen domestic manufacturing and support a long-term goal of producing 40% of total DRAM in the U.S. Micron, which already is building up to four DRAM fabs in New York and expanding R&D in Idaho and Virginia, is aiming to capture more of the AI memory “supercycle.” The move places additional competitive pressure on SK Hynix and Samsung, which have long benefited from integrated Asian operations. The article frames the build-out as a shift from earlier piecemeal U.S. investments to an end-to-end domestic ecosystem spanning wafer fabrication to advanced packaging.
