Micron has started manufacturing 1α (1-alpha) DRAM at its Manassas, Virginia facility, marking the most advanced memory chip production ever achieved on American soil.
The 1α DRAM node targets long-lifecycle memory for critical applications. It supports DDR4 and LP4 products across automotive, defense, aerospace, industrial, networking, and medical device sectors. Micron is the only US-based manufacturer of memory chips, giving it a unique position in strengthening domestic supply.
Micron expects qualified 1α DRAM production from the Manassas facility by the end of calendar year 2026. The more than $2 billion investment will quadruple DDR4 wafer supply at the site. This directly benefits US automotive, defense, aerospace, and industrial customers.
The Manassas milestone is part of Micron’s broader $200 billion US investment plan. That plan also includes major projects in Boise, Idaho, and Clay, New York. Together, these projects are expected to create an estimated 90,000 American jobs and strengthen domestic economic and national security infrastructure.
Micron CEO Sanjay Mehrotra called the development an important step in the company’s long-term US expansion. He said the achievement reflects Micron’s commitment to customers and industries that depend on long-lifecycle memory for critical applications.
US Trade Representative Ambassador Jamieson Greer tied the investment to the Trump administration’s manufacturing agenda. He said the semiconductor manufacturing base drives American innovation and creates more resilient supply chains.
Micron also positioned its memory and storage solutions as central to the AI revolution. AI-driven demand is reshaping every market the company serves, from data centers to automobiles to factory floors. Advanced memory has become a strategic asset in that environment. The Manassas facility handles long-lifecycle memory needs, while leading-edge facilities in Idaho and New York address the most advanced AI workloads.
