CXMT G5 DRAM production is now underway in China. It marks one of the clearest signs yet that the country’s chipmakers are closing the gap with Samsung and SK Hynix. That progress comes despite years of export restrictions on advanced lithography gear.
Chinese memory chipmaker CXMT announced the milestone at the 2026 World Manufacturing Convention in Hefei on September 20. It unveiled its fifth-generation DRAM platform, known as the G5 Platform.
What CXMT G5 DRAM Production Actually Achieves
The G5 Platform uses quadruple patterning. That reaches an 11.95-nanometer active-area half-pitch for memory arrays. CXMT said its capacitor aspect ratio reaches 45:1. The core cell array height has shrunk to 6,762 nanometers. In plain terms, the company packs more memory into a smaller footprint. It says the platform yields at least 50% more dies per wafer than its predecessor.
How CXMT Got Here Without ASML’s Banned Machines
The achievement stands out for one reason. CXMT built it without access to ASML’s most advanced extreme ultraviolet lithography tools. Those remain subject to export controls. The company instead relied on quadruple patterning with existing equipment. That workaround took years to refine. It appears to be paying off at scale now.
Multiple patterning is not new in chipmaking. But matching the density gains EUV lithography delivers in a single pass usually costs more. It means more process steps, more time and more cost per wafer. CXMT chose to absorb that complexity rather than wait for policy changes. That choice reflects the broader bet Chinese chipmakers have made since export controls tightened.
What This Means for Samsung, SK Hynix and Global Memory Prices
CXMT now claims the title of China’s largest DRAM supplier. It also claims fourth place worldwide by market share. The company has scaled fast. It grew from roughly 40,000 wafers a month in 2020 to about 300,000 today. That output spans its 12-inch fabs in Hefei and Beijing. It targets 350,000 to 375,000 wafers monthly by year-end 2026. That capacity growth adds real supply to a global memory market squeezed by AI-driven demand.
The Products Already Shipping on the New Platform
Two 24-gigabit LPDDR5X products are already in mass production. They come in 496-ball and 245-ball packages for smartphones and portable electronics. Both are integrated into mainstream Chinese flagship handsets already, the company says.
The Bigger Picture for China’s Chip Ambitions
CXMT’s progress fits a wider Chinese push to build a self-sufficient semiconductor supply chain. That priority hardened after successive rounds of US export controls on advanced chipmaking equipment. Beijing has funneled heavy state-backed investment into domestic memory and logic chip production for years. CXMT’s rise from a minor player to a top-four global DRAM supplier is one of the clearest results so far.
Whether the company can keep closing the gap at the cutting edge remains an open question. Both Korean rivals keep investing heavily in their own next-generation nodes. Neither shows signs of slowing down.
Which Chinese Phone Makers Are Buying In
CXMT has not publicly named every customer using the new LPDDR5X chips. Industry watchers tracking teardown reports say several major Chinese smartphone brands have already qualified the parts for mainstream, non-flagship models. That matters commercially. Winning approval in China’s huge domestic phone market gives CXMT steady volume, even before it competes for premium international designs.
Analysts say the bigger prize is qualification with global device makers outside China. That would require CXMT to match not just density but also long-term reliability data that Samsung and SK Hynix have built up over decades. CXMT has not said when, or whether, it plans to pursue that qualification process.
Where CXMT Goes From Here
Capacity is still climbing toward its year-end target. CXMT’s next test is sustaining yields at scale while narrowing the technology gap further. Industry watchers expect the company’s progress to keep pressuring global memory pricing. That dynamic is already squeezing device makers worldwide this year.
The next milestone to watch is server and data-center memory. Can CXMT push the G5 platform into that higher-capacity segment? It remains dominated even more heavily by Samsung, SK Hynix and Micron than the mobile market CXMT has targeted so far. Analysts see that as the real test of whether CXMT can compete at the very top of the market, not just at the budget end.
