Micron Technology on May 22, 2026, began making 1-alpha DRAM at its Manassas, Virginia, fab, which the company calls the most advanced memory ever produced in the USA.
The details
- The 1-alpha node will quadruple Micron’s DDR4 wafer supply in Manassas. The chips are long-lifecycle DDR4 and LP4 memory for automotive, defense and aerospace, industrial, networking and medical devices.
- Micron is investing more than $2 billion to expand and modernize the fab, which supports more than 3,100 direct manufacturing and community jobs.
- Potomac Local reported $275 million in finalized CHIPS and Science Act funding and said qualified production is expected by the end of 2026.
- The project is part of Micron’s roughly $200 billion USA investment plan, which also includes Idaho and New York.
“We are proud to bring advanced 1α DRAM manufacturing to American soil, strengthening domestic supply for U.S. customers and the global markets we serve.”
Sanjay Mehrotra, Chairman, President and CEO, Micron Technology
Why it matters for Made in USA
Micron says it is the only USA-based memory manufacturer. Memory chips sit inside most electronics, so more USA output makes it more realistic for defense, automotive and medical device makers to source key chips in the USA.
