TrendForce reports that Micron’s Fab 6 facility in Virginia, U.S., has commenced LPDDR4 and DDR4 production utilizing the advanced 1αnm process. This move is primarily aimed at serving customers in critical sectors such as automotive, defense, and aerospace. The capacity expansion is a strategic reallocation of Micron’s internal production resources and does not pertain to the supply of consumer-grade DDR4.

At Fab 6, the production emphasis will predominantly shift to LPDDR4, with DDR4 also being manufactured. By the fourth quarter of 2027, the total number of wafer starts is projected to reach 1.5 times that of the second quarter of 2026. Specifically, mass production of the 1αnm process wafers will kick off by the end of 2026, scaling up to four times the initial volume in 2027.

Conversely, the 1αnm process operations at the OMT plant will experience a gradual quarterly reduction in production, with no plans for further expansion of DDR4 and LPDDR4 output. Consequently, this development is not expected to alleviate the ongoing DDR4 supply shortage.
