The global expansion blueprint of trillion-dollar Micron: Simultaneous capacity expansion in the US, Japan, and Singapore, with new production capacity scheduled all the way to 2030.

Micron Technology is transforming the surge in AI-driven memory demand into a multi-continent capacity expansion campaign.

Micron’s stock price soared 19% overnight, nearing the $1 trillion market capitalization mark, and closed at a historic high, setting its 28th peak this year. Meanwhile, Micron management expects tight memory market supply to continue into 2026 and beyond, and is accelerating global factory construction plans, with most new capacity expected to come online from 2027 onwards.

This expansion blueprint covers the United States, Japan, Singapore, India, and Malaysia, spanning DRAM, HBM, and NAND product lines, with the new capacity timeline stretching out to 2030. For investors, this means Micron’s capital expenditure cycle will last for several years, while the pace of supply release will deeply affect the memory market’s supply and demand structure.

United States: Idaho and New York focus on advanced nodes, Virginia expands DDR4

Micron’s expansion in the U.S. has recently accelerated. On May 22, Micron announced the official start of 1α (1-alpha) DRAM mass production at its Manassas wafer fab in Virginia. This is Micron’s most advanced DDR4 manufacturing process, and the company says it will quadruple DDR4 wafer output, mainly serving automotive, industrial, networking, medical, and defense aerospace applications with long lifecycles.

According to TrendForce analysis, the expansion of Manassas Fab 6 mainly reflects an internal redistribution of Micron’s capacity, rather than a renewed focus on consumer electronics DDR4 supply. TrendForce expects Fab 6’s monthly wafer production to reach 1.5 times its Q2 2026 level by Q4 2027, with 1α mass production expected around the end of 2026.

For advanced nodes, Micron’s core operations are concentrated in Idaho and New York. According to STOCK Analysis meeting notes, at JPMorgan’s 54th Global Technology, Media & Communications Conference, Micron’s management said Idaho Fab 1 construction is progressing smoothly, with wafer output timing moved forward from H2 2027 to mid-2027; Idaho Fab 2 is expected to begin wafer production at the end of 2028.

Micron also stated that after completing the second Idaho fab, it plans to introduce advanced HBM packaging capabilities in the U.S. The coordinated layout of the two Idaho fabs and R&D center is expected to create economies of scale and accelerate the launch of advanced products such as HBM. In New York, Micron held a groundbreaking ceremony ahead of schedule this January, with production expected to start in 2030, ramping up capacity over the following years.

Japan: Hiroshima fab about to begin, HBM shipment target set for 2028

According to Nikkei News, Micron plans to invest about 1.5 trillion yen (about $9.6 billion) to build next-generation memory chip production facilities in western Japan. Construction is scheduled to start in May 2026 at Micron's existing Hiroshima fab site, with the target for HBM chip shipments set around 2028.

Although Micron has not formally confirmed this plan, local Japanese media have documented substantial groundwork. According to RCC Broadcasting, land development on approximately 9.5 hectares west of the Hiroshima fab began this March, and site signage shows related construction will continue until February 2028.

Additionally, according to Higashihiroshima Digital, Micron Memory Japan opened a new office in Saijo town Showa-machi in mid-March, with approximately 2,320 square meters of office space on the first floor housing about 300 employees, covering administration, marketing, and engineering teams.

Singapore and Taiwan: Dual focus on NAND and HBM

Singapore serves as the core for Micron’s global NAND capacity expansion. Earlier this year, Micron held a groundbreaking ceremony for its new NAND fab in Singapore, with wafer output expected to start in the second half of 2028.

Meanwhile, at the JPMorgan conference, Micron stated that construction of its Singapore HBM facility is progressing well—it broke ground in early 2025, with output expected to begin in 2027, complementing its existing HBM operations in Taiwan.

In Taiwan, Micron has continued to expand after acquiring PSMC’s Tongluo fab. Management says the twin fab is expected to start construction this summer; the existing Tongluo P5 fab is expected to deliver meaningful DRAM wafer output in the second half of calendar year 2027; the new Tongluo fab is expected to support meaningful product shipments starting in fiscal year 2028.

India and Malaysia: Backend packaging and testing sustain the global supply chain

Beyond frontend wafer manufacturing, Micron has positioned India and Malaysia as key backend packaging and testing centers. According to Adda 247 Current Affairs, Micron’s fab in Sanand, India, will officially start production in March 2026, marking the launch of India’s first advanced memory ATMP (Assembly, Test, Mark, and Packaging) operations. According to Business Standard, once the fab reaches full capacity, it could contribute up to 10% of Micron’s global output, serving both domestic and international markets.

In Malaysia, according to The Sun, Micron’s Malaysian operations began with the establishment of its Muar facility in Johor in 2010, later expanding to Penang, where next-generation manufacturing capability is being developed. Currently, Micron Malaysia is responsible for packaging and testing NAND, DRAM, SSDs, and memory modules, supplying products for diverse AI applications from data centers to edge devices.
