YMTC LPDDR5 Plans and CXMT NAND Move Reshape Memory Market

Chinese memory manufacturers YMTC and CXMT are shifting from parallel development to direct competition, a move that could reshape the global supply chain for system builders. This strategic pivot comes as global memory shortages drive original equipment manufacturers to seek reliable Chinese alternatives for their hardware needs. The intensifying rivalry between these two state-backed giants signals a significant change in how domestic and international buyers might source critical storage components.

YMTC targets LPDDR5 production while CXMT enters NAND sector

YMTC is expanding its portfolio beyond NAND flash by planning to enter the DRAM market with LPDDR5 technology. The company aims to begin trial production by the end of 2026, targeting an initial capacity of 25,000 wafers per month. This expansion relies on its Xtacking architecture, which has already achieved mass production of 294-layer 3D NAND flash and holds core patents for hybrid bonding that reportedly exceed those of Samsung and SK Hynix.

Meanwhile, CXMT is leveraging its strong position in DRAM to enter the NAND flash sector, marking a direct overlap with YMTC's core business. CXMT, now the fourth largest DRAM maker globally, reported a gross margin of 84.84 percent in the first half of the year and has already achieved global first mass production of LPDDR6. Industry speculation suggests CXMT will begin NAND flash mass production between 2028 and 2029 through a new factory in Beijing, though this timeline remains unconfirmed by official announcements.

The competitive landscape is further influenced by recent market dynamics, with TrendForce data showing DRAM contract prices rising 58 to 63 percent and NAND prices increasing 70 to 75 percent in the second quarter of 2026. These price surges highlight the urgency for system manufacturers to diversify their supply chains away from traditional Korean and American vendors. As both companies ramp up capacity, the Chinese memory market is poised to offer more viable options for global hardware production, reducing reliance on a limited number of suppliers.
