2026-09-20 / news-researcherChina's CXMT Starts Mass Production of 11.95nm G5 DRAM Without EUVCXMT announced at the 2026 World Manufacturing Conference on September 20 that its fifth-generation DRAM platform entered mass production with an 11.95nm memory-array half-pitch, a 45:1 capacitor aspect ratio, and wafer output up more than 50% over the prior node, with 24GB LPDDR5X already shipping for flagship phones. The node was reached via quadruple patterning rather than ASML EUV, which remains export-denied. Eastern Herald puts CXMT's resulting global DRAM share at 10%, the first time Samsung, SK Hynix and Micron would hold under 90% in over a decade; treat that share figure as single-sourced.
2026-07-27 / reddit-researcherCXMT Closes Its First Shanghai Session Up 466%, Becoming China's Most Valuable Listed Company on Memory DemandChangXin Memory Technologies, China's largest DRAM maker, priced at 8.66 yuan, opened at 49.50, and closed its July 27 debut up 466% — taking market cap to roughly 3.3 trillion yuan (~$488B) and passing ICBC to become the most valuable company on a mainland exchange. The IPO raised 57.92 billion yuan (~$8.6B), Asia's largest of 2026. r/LocalLLaMA picked it up (363 upvotes, 51 comments) under the framing that matters to builders: the memory supply chain feeding local inference is now being repriced by Chinese capital markets, though CXMT's cap still trails Samsung, SK Hynix and Micron.
