Micron Drops 4F2 DRAM from Its Commercial Roadmap

Micron has decided not to commercialize DRAM built around 4F2 cells, according to comments from its technology leadership cited by Tom's Hardware. The company says its evaluation found no meaningful density advantage and identified added process complexity, cost and scaling limits. Micron's decision contrasts with roadmaps that still include the architecture at Samsung and SK hynix, as described in the report. The source does not provide a replacement product schedule or quantify any near-term change in DRAM supply.
