Micron Breaks Ground on $100 B New York Megafab, Targeting Mass DRAM Production by 2030

Micron Breaks Ground on New York Megafab, Targeting 2030 Mass Production

Micron has begun construction on its largest semiconductor plant to date, the New York megafab, in Onondaga County. A groundbreaking ceremony is scheduled for January 16, 2026, local time, as the company pushes ahead to begin mass production of cutting‑edge DRAM in the United States by 2030.

With all environmental assessments and required permits completed, site work will proceed in earnest to support the full-scale project.

Key Facts	Details
Project name	new York Megafab
Location	Onondaga county,New York,USA
Total investment	Up to $100 billion (largest private investment in New York State history)
Fabs planned	Up to four,constructed in stages; first two will be high‑capacity DRAM fabs
Clean room size	600,000 square feet per fab; total clean room area across four fabs = 2.4 million square feet
timeline	Groundbreaking Jan 16, 2026; Hiroshima fab operational 2028; Idaho fab 2029; New York mass production 2030
Purpose	To secure a stable supply of high‑performance DRAM for AI workloads in the United States

Micron plans two initial mass‑production DRAM fabs at the New York site, each with a 600,000‑square‑foot clean room. The four fabs altogether would deliver 2.4 million square feet of clean‑room space, roughly the size of 40 soccer fields, once complete.

The megafab is expected to become a cornerstone for U.S. memory supply as AI systems spur rising demand for memory technology. The company says the project will help ensure a stable, domestic DRAM supply crucial for AI calculations.

“The groundbreaking of the New York Megafab is a significant milestone for both Micron and the United States,” said Sanjay Mehrotra, Micron’s chief executive. “In a global economy entering the AI era, leadership in advanced semiconductors will be the cornerstone of innovation and economic prosperity.”

Micron is expanding its global DRAM capacity, including high‑bandwidth memory (HBM). Prior to the New York site, the company has announced a Hiroshima fab slated to begin operation in 2028 and an Idaho fab planned to start in 2029.

Evergreen insights

As artificial intelligence expands across industries, demand for high‑performance memory like DRAM is likely to keep rising. Building domestic manufacturing capacity reduces exposure to international supply shocks and can help stabilize access to essential tech infrastructure during global disruptions.

Megafabs also bring regional economic benefits,including skilled jobs and strengthened supplier networks,while accelerating progress in memory technologies such as high‑bandwidth memory that power AI workloads and data centers.
