China's CXMT Starts Mass Production on 5th-Generation DRAM Process

CXMT's G5 DRAM process is a direct challenge to established players. Its 11.95-nanometer half-pitch for active areas reflects a significant advance. The 50% increase in potential dies per wafer for 8Gb products lowers cost per chip. This positions CXMT to gain further market share in commodity DRAM, where it already holds 9.5% of global revenue.

The move by CXMT will pressure Samsung, SK hynix, and Micron. These incumbents have shifted focus to high-bandwidth memory (HBM) and high-capacity server DDR5. Chinese suppliers are now filling the commodity market gap. This could force the global trio to defend prices more aggressively in segments they previously de-emphasized.

The thing to watch is how CXMT's stated process capability translates into actual yields. While the company claims parity with advanced nodes, specific yields and monthly output remain undisclosed. If CXMT achieves high yields at scale, it will reshape the commodity DRAM market more quickly than expected, potentially stopping price increases in the second half of next year.
