January 14, 2026 /SemiMedia/ — Micron Technology said on Thursday it has begun construction of a major semiconductor manufacturing complex in New York state, marking the start of a project that could involve up to $100 billion in investment over the coming decades.

Micron expands U.S. memory manufacturing for AI demand

The New York facility, located in Onondaga County, is expected to host as many as four fabrication plants focused on advanced memory production, including DRAM. Micron said the site will play a central role in supporting growing demand from artificial intelligence servers and data centre applications.

Micron first announced the project in October 2022, with construction initially planned for mid-2024. The timeline was later pushed back due to an extended environmental review process. The company now expects the first fab at the site to begin production around 2030, with additional fabs coming online in subsequent years.

The New York expansion forms part of Micron’s broader strategy to increase U.S.-based memory manufacturing capacity and strengthen supply chain resilience. The company has previously said it aims to significantly lift the share of advanced DRAM produced in the United States over the next decade.

CHIPS Act incentives support long-term DRAM investment

Micron has secured incentives under the U.S. CHIPS and Science Act, helping underpin its long-term capital spending plans. As AI accelerators drive higher demand for high-performance and high-bandwidth memory, the company views the New York site as a strategic asset to enhance its competitiveness in the global memory market.
