RAM shortage deepens with CXMT

AppleInsider reported on August 5 that the global RAM and SSD shortage is expected to worsen before supply improves, extending a squeeze that has already pushed up memory prices across consumer hardware. PC Gamer reported the same day that ChangXin Memory Technologies, or CXMT, is taking share from Samsung Electronics, SK hynix and Micron even as the broader shortage persists. TechTimes added a separate risk: Chinese law requires newly discovered vulnerabilities in network products to be reported to authorities within 48 hours, creating a disclosure gap if CXMT memory is used in shipped PCs. ### Why is a new supplier not easing the shortage? AppleInsider said on August 5 that tighter RAM and SSD supply is still being driven by capacity constraints and strong demand, with relief not expected soon. The report said manufacturers are benefiting from elevated pricing even as buyers face a longer crunch. (appleinsider.com) Semafor reported that AI data-center demand is expected to absorb 70% of memory chip production in 2026, while PC Gamer said CXMT’s gains do not change the near-term supply picture overnight. That leaves the market adding a new participant without materially loosening availability in the short run. ### How much share has CXMT actually taken? (appleinsider.com) PC Gamer, citing Counterpoint Research, said CXMT now holds 7% of global DRAM revenue share. The same figures put Samsung at 39%, SK hynix at 26% and Micron at 25%, leaving four companies with 97% of the market by revenue. TweakTown and Sammy Fans separately cited Counterpoint numbers showing Samsung leading the DRAM market in 2026 and CXMT making the largest gains among challengers. (semafor.com) Those reports point to the same shift: CXMT is growing, but the market remains concentrated around the established three suppliers plus one rising Chinese entrant.

The report said those manufacturers completed qualification around mid-2026 and began using small quantities in limited notebook models. (tweaktown.com) BizChosun and Seoul Daily, citing Nikkei Asia, also reported that HP, Asus and Acer had begun applying CXMT DRAM to some laptop models, with volumes still limited. The reports said the products were being sold outside the United States. ### What is the security wrinkle around Chinese disclosure rules? TechTimes said Chinese regulations on security vulnerabilities in network products require reporting to authorities within 48 hours of discovering a flaw. (techtimes.com) In practice, that means a vulnerability involving affected CXMT-equipped systems could be disclosed to Beijing before the laptop maker or device owner is notified, according to the report. (biz.chosun.com) The report did not say such a vulnerability had been exploited in CXMT laptop memory already on sale. It described the issue as a structural disclosure asymmetry tied to the legal reporting sequence. ### Why does this matter for firmware and system design? The current shortage puts memory cost and availability back into system planning. (techtimes.com) AppleInsider’s report on tightening RAM and SSD supply, combined with the limited pace of new CXMT volume, means designers cannot assume cheaper or easier memory in the near term. For embedded and firmware teams, that favors static allocation, tighter stack budgeting and bounded buffer use over designs that assume abundant headroom. The next concrete developments to watch are broader laptop rollouts by HP, Asus and Acer and any updated market-share data from Counterpoint on CXMT’s position against Samsung, SK hynix and Micron.
