China’s CXMT Says It Has Reached Advanced DRAM Mass Production, Challenging Samsung, SK Hynix and Micron in Memory Chips

Sep 21, 2026, 4:14 AM UTC · Primary ticker $MU

China's CXMT announced it has begun mass production of fifth-generation DRAM using advanced technology, aiming to compete directly with Samsung, SK Hynix, and Micron. This development signifies a significant step in China's domestic chip manufacturing capabilities, potentially disrupting the global memory chip market.

CXMT's announcement of mass production of advanced DRAM using 11.95nm technology is a major development. It signals China's growing self-sufficiency in a critical technology sector, directly challenging the established dominance of Samsung, SK Hynix, and Micron. This could lead to increased competition, potential price pressure, and market share shifts in the global DRAM market in the long term. For traders, this presents a key risk for the incumbent memory chip giants as a new, state-backed competitor enters the advanced production arena.
