Micron Technology has started manufacturing 1α (1-alpha) DRAM memory at its Manassas, Virginia fabrication facility, marking a major milestone in the company’s effort to expand semiconductor memory production in the United States.
The company said the 1α node is the most advanced memory technology ever produced in the U.S. The manufacturing expansion is part of Micron’s broader $200 billion domestic investment strategy focused on semiconductor manufacturing and research.
The announcement was made during an event at the Manassas facility attended by senior U.S. administration officials, lawmakers, Virginia state representatives, industry partners, and academic institutions.
Micron said the Virginia facility will manufacture long-lifecycle memory products for critical sectors including automotive, aerospace, defense, industrial systems, networking, and medical devices. The 1α node will support DDR4 and LP4 memory products used in applications that require long-term reliability and supply continuity.
The company expects qualified 1α DRAM production from the Manassas fab by the end of calendar year 2026. Once production ramps fully, Micron said the expansion will quadruple DDR4 wafer output from the facility.
The project includes more than $2 billion in investments aimed at expanding and modernising the fab. According to the company, the site currently supports more than 3,100 manufacturing and community jobs. The expansion is backed by federal, state, and local incentives.
Micron Chairman, President, and CEO Sanjay Mehrotra said the milestone reflects the company’s long-term commitment to strengthening America’s domestic memory supply chain.
He said advanced memory manufacturing is becoming increasingly important as industries adopt artificial intelligence, connected systems, industrial automation, and high-performance computing technologies.
The expansion comes amid broader efforts by the United States to rebuild domestic semiconductor manufacturing capacity and reduce dependence on overseas supply chains. Governments and technology companies have accelerated investments in local semiconductor production following global chip shortages and rising geopolitical tensions over the past several years.
Memory technologies are also becoming more critical as AI infrastructure grows rapidly. AI data centres, cloud platforms, autonomous systems, and edge computing applications require higher-performance memory with lower latency and improved power efficiency.
Micron said its memory and storage products are playing an increasingly important role in the AI ecosystem. The company added that its product portfolio spans both advanced AI memory solutions and long-lifecycle industrial memory technologies.
Speaking at the event, U.S. Secretary of Commerce Howard Lutnick said Micron’s investment would help expand American production of advanced memory semiconductors used in industrial, automotive, aerospace, and defense sectors.
U.S. Trade Representative Jamieson Greer said the expansion reflects wider efforts to strengthen U.S. manufacturing and semiconductor supply chain resilience.
U.S. Senator Mark Warner said the modernisation project would help strengthen national security and improve American competitiveness in advanced semiconductor technologies. Senator Tim Kaine also highlighted the importance of increasing domestic semiconductor manufacturing through initiatives such as the CHIPS and Science Act.
Virginia Governor Abigail Spanberger said the project reinforces Virginia’s position as a growing hub for advanced manufacturing and semiconductor investment.
Micron also provided updates on its wider U.S. manufacturing expansion plans. Earlier this year, the company broke ground on its memory manufacturing complex in New York. Site preparation activities are also underway for additional fabrication facilities in Idaho.
The company expects initial wafer output from its first Idaho fab in mid-2027. Ground preparation has also started for a second Idaho fab.
Combined, Micron said its planned U.S. manufacturing projects are expected to create nearly 90,000 jobs across construction, manufacturing, supply chain operations, and community support sectors.
Alongside manufacturing investments, Micron has committed more than $325 million toward workforce development and community initiatives across Virginia, Idaho, and New York.
The investment includes semiconductor curriculum development, partnerships with universities and community colleges, apprenticeship programs, and STEM education initiatives designed to expand access to semiconductor careers.
In Virginia, Micron has partnered with Northern Virginia Community College and the National Institute for Innovation and Career Advancement to support semiconductor technician apprenticeship programs.
The company said the Micron Registered Apprenticeship Program is designed to create direct pathways into semiconductor technician roles at the Manassas facility.
Micron is also supporting regional STEM education through the Micron STEM Opportunity Fund, which aims to reach more than 16,000 K-12 students across Northern Virginia.
Veterans also form a significant part of the Manassas workforce. According to Micron, approximately one in ten employees at the facility are veterans. The company works with military transition programs, local veteran organizations, and Virginia-based military installations to support recruitment and workforce development.
Industry analysts said Micron’s latest expansion reflects the growing importance of memory technologies in the AI era and the wider global shift toward localised semiconductor manufacturing.
Analysts also noted that advanced memory production has become strategically important for governments seeking stronger control over critical technology supply chains tied to AI, defense, automotive systems, and industrial infrastructure.
