Chinese semiconductor firm CXMT has begun mass production on its G5 chip manufacturing platform, significantly increasing storage density and bringing its technology close to that of established leaders Samsung and SK Hynix.
- G5 platform uses 11.95nm tech with quadruple exposure.
- LPDDR5X chips targeted at mid-to-high-end smartphones.
- CXMT’s global DRAM revenue share grew to 9.5% in Q2 2026.
What happened
Changxin Memory Technologies (CXMT), a leading Chinese memory chip manufacturer, announced it has adopted its fifth-generation G5 technology platform for mass production. This new platform enables a significant increase in storage density, producing at least 50% more dies per wafer compared to the previous generation. The platform incorporates advanced techniques like quadruple exposure to reach an 11.95 nanometer manufacturing node.
CXMT showcased mass-produced LPDDR5X DRAM chips based on the G5 platform, designed for mobile devices with a capacity of 24 gigabits, representing a 50% capacity boost over earlier models. These products are aimed at mid-to-high-end smartphones and portable electronics, signaling the company's ongoing commitment to technological progress.
Why it matters
This technological milestone narrows CXMT’s gap with global semiconductor powerhouses such as Samsung and SK Hynix, who currently lead with approximately 10-nanometer process nodes. CXMT's advancements demonstrate China’s growing capabilities in advanced chip manufacturing, a key focus amid ongoing global supply chain and geopolitical challenges.
The progress not only strengthens CXMT’s domestic position—evidenced by adoption among Chinese smartphone brands like ZTE’s Nubia, Xiaomi, and Transsion—but also enhances its competitiveness on the international stage. Its increased DRAM revenue share to 9.5% in Q2 2026 highlights the gains the firm is making in a market typically dominated by South Korean and US companies.
What to watch next
Market observers will be tracking CXMT’s ability to sustain and improve this manufacturing node technology to challenge further the leading players' dominance in the global DRAM market. Continued iteration on the G5 platform and future generations will be critical as customer demand grows for higher-speed, low-power memory chips.
Additionally, CXMT’s traction with domestic smartphone brands, especially in the premium segment, will be a key indicator of the company’s long-term viability and influence. Its progress may also impact China’s broader semiconductor ambition amid efforts to reduce reliance on foreign technology.
