China's CXMT says it will launch 4F² server DRAM by year‑end, sending Micron, Samsung and SK Hynix shares lower
ChangXin Memory Technologies (CXMT) announced it will unveil DDR5 registered DIMM server memory using a next‑generation 4F² cell architecture by the end of 2026. The news triggered an intraday sell‑off in major memory makers, with Micron Technology, Samsung Electronics and SK Hynix all posting double‑digit percentage declines. CXMT’s claim positions it to challenge the high‑value server‑memory market that has been dominated by the three incumbents.
Why it matters
The share drops reflect heightened competitive pressure on the server‑memory segment, which could compress margins for the established players and affect investors’ exposure to the memory sector (the company notes the broader correction in memory stocks)【1】.
