ChangXin Memory Technologies completed verification of its LPDDR6 chips at 12.8 Gbps, matching the performance of Samsung, SK Hynix, and Micron. The milestone matters because these three firms have controlled the global memory chip market for decades. Now a Chinese producer is sitting at their table.
The company's new chips run on a base speed of 10.7 Gbps using its G4 process node, with a design density of 16Gb. That positions them squarely in the low-power DRAM segment built for smartphones. CXMT's previous LPDDR5X generation already hit 10,667 Mbps, aligned with what the Western incumbents were shipping. This next step closes what little gap remained.
From startup to number four in one year
CXMT's Q1 2026 revenue hit $7.5 billion, a 700% year-over-year jump. More striking, its global DRAM market share climbed to 8% from 3% the year before, making it the world's fourth-largest DRAM maker. In the span of 12 months, the company went from a regional player to a rival no one could ignore.
The Shanghai STAR Market IPO in late July raised $8.55 billion. Shares exploded 466% on day one, a signal that Beijing sees this as strategic infrastructure. US export restrictions on advanced semiconductors have flipped the narrative. Self-reliance stopped being nice-to-have policy and became survival. CXMT operates 100,000 monthly wafer capacity today and is building more plants in Beijing to push that number higher.
Xiaomi, OPPO, and Vivo are already buying CXMT memory. Western names like Apple are reportedly kicking the tires. That's the inflection point investors are watching. Once LPDDR6 moves from the lab to mass production lines, we'll know if CXMT can deliver at scale. A confirmed supply deal with Apple or another major Western OEM would validate the technology in the most demanding environment on the planet.
