CXMT G5 DRAM Enters Mass Production With 50% More Dies

CXMT G5 DRAM Platform: Entity Overview

ChangXin Memory Technologies (CXMT) is China’s leading DRAM manufacturer, supplying memory chips for smartphones, PCs, and servers. The company’s fifth-generation technology platform, dubbed G5, has entered mass production, increasing gross die production per wafer by at least 50% compared to the previous generation while delivering improved power efficiency at a lower cost. The G5 platform is now central to CXMT’s push toward the global memory market.

CXMT’s G5 DRAM platform is now in mass production and marks a significant step toward challenging the dominance of Samsung, SK Hynix, and Micron in the global memory chip market.

What Is CXMT’s G5 DRAM Platform?

CXMT’s G5 is the company’s fifth-generation DRAM manufacturing platform, now in mass production. It produces 24-gigabit per-die LPDDR5X memory chips using an 11.95nm active-area half-pitch achieved through quadruple patterning technology, resulting in at least a 50% increase in gross die production per wafer over the prior generation.

According to CXMT, the new platform achieved a “quantum leap” in storage density, and the company stated that the G5 platform delivers improved power efficiency at a lower cost. Two LPDDR5X products based on G5 were unveiled at the 2026 World Manufacturing Convention in Hefei, and CXMT said the products are already in mass production.

CXMT’s G5 platform enters mass production with at least 50% more dies per wafer and a 24-gigabit per-die LPDDR5X capacity, representing a 50% increase over the previous generation.

How Does the G5 Platform Improve Storage Density?

CXMT’s G5 platform increases storage density by using quadruple patterning to achieve an 11.95nm active-area half-pitch for its memory arrays. This improvement brings the company closer to what CXMT describes as “the world’s most advanced mass-production memory platforms.”

The density gain translates directly into production economics: gross die production per wafer increases by at least 50% compared to CXMT’s previous-generation platform. The company also reported improved power efficiency at a lower cost, making the G5 platform more competitive on both performance and price.

The G5 platform’s 11.95nm active-area half-pitch, achieved through quadruple patterning, delivers at least a 50% increase in gross die production per wafer over CXMT’s previous-generation platform.

How Does G5 Compare to Samsung and SK Hynix?

Samsung and SK Hynix, South Korean memory chipmakers, are already using 10nm-class process technology for DRAM production. CXMT’s G5 platform achieves an 11.95nm active-area half-pitch, which the company says brings it closer to the world’s most advanced mass-production memory platforms currently available.

The competitive landscape also includes Micron, as CXMT’s rise challenges the long-standing dominance of Samsung, SK Hynix, and Micron across the global memory chip market covering smartphones, PCs, and servers. The G5 platform’s density and cost improvements position CXMT as a stronger contender in this space.

Samsung and SK Hynix already use 10nm-class process technology, while CXMT’s G5 platform achieves an 11.95nm active-area half-pitch, narrowing the gap with the world’s most advanced memory platforms.

Who Is the Target Market for CXMT’s G5 Products?

CXMT’s new G5-based LPDDR5X memory products are designed for “mid-to-high-end smartphones and portable consumer electronics,” according to the South China Morning Post. The company stated it would “continue to advance technological iterations to meet global market demands” going forward.

CXMT has already been gaining traction among local smartphone manufacturers, with high-end LPDDR5X DRAM chips making their way into flagship Chinese handsets. One example is the Nubia NaviX Ultra, which went on sale last Wednesday and comes with ByteDance’s Doubao artificial intelligence assistant.

Common Questions

Has CXMT’s G5 DRAM platform officially entered mass production?

Yes. CXMT announced that its fifth-generation G5 technology platform has entered mass production. The company also confirmed that two LPDDR5X products based on the G5 platform are already in mass production, following their unveiling at the 2026 World Manufacturing Convention in Hefei.

How many more dies per wafer does the G5 platform produce compared to the previous generation?

The G5 platform achieves at least 50% more gross die production per wafer than CXMT’s previous-generation platform. The company attributed this density gain to quadruple patterning technology and an 11.95nm active-area half-pitch for its memory arrays.

Which products currently use CXMT’s G5-based LPDDR5X DRAM chips?

CXMT’s high-end LPDDR5X DRAM chips have made their way into flagship Chinese handsets, including the Nubia NaviX Ultra, which includes ByteDance’s Doubao artificial intelligence assistant. The chips are designed for mid-to-high-end smartphones and portable consumer electronics.
