CXMT to launch 4F² DDR5 RDIMM before year-end, leapfrogging Samsung by ~2 years

CXMT President Dr. Cao Kanyu said the company will introduce a server-grade DDR5 RDIMM based on the 4F² memory cell architecture before the end of 2026, roughly two years ahead of Samsung's 2028 roadmap. The 4F² design boosts cell density by 30–50% and cuts cell area by about 33% at the same feature size.

• CXMT targets 4F² DDR5 RDIMM launch before end of 2026
• Samsung plans 4F² only in 2028 — about two years behind
• 4F² architecture raises DRAM cell density by 30–50%
• CXMT scaling to 300,000 wafers per month, building two new fabs
