CXMT targets 4F² DRAM production two years ahead of Samsung, but can China close technology gap?

What happened

ChangXin Memory Technologies (CXMT) plans to mass-produce next-generation 4F² DRAM by the end of 2026, potentially ahead of South Korean rivals Samsung Electronics and SK Hynix. The announcement has fuelled speculation that China's memory technology is approaching or surpassing South Korean capabilities, while positioning CXMT for an early entry into the emerging 3D DRAM market. This remains a plan; mass production has not yet been achieved.
