Chinese memory chipmaker ChangXin Memory Technologies, or CXMT, is reportedly nearing the end of research and development validation for its first LPDDR6 chip, moving it closer to mass production in the race for next-generation mobile memory.
Citing industry sources, domestic media reports said the chip is designed to reach a data rate of 12,800 megabits per second, with a base operating rate of 10,667 Mbps when paired with a system-on-chip.
The chip reportedly features a 16-gigabit die, a packaged capacity of 16 gigabytes and a 1,295-ball package-on-package design. Its power efficiency, reliability, availability and serviceability have also been improved from CXMT’s LPDDR5X products, according to the reports.
Published by the Joint Electron Device Engineering Council (JEDEC) Solid State Technology Association in July 2025, the LPDDR6 standard aims to meet growing demand for faster and more energy-efficient memory in mobile devices and AI applications. Its higher data throughput is expected to support memory-intensive tasks such as running AI models directly on devices and high-frame-rate gaming.
The reported progress would place CXMT among the early contenders in the industry’s transition to LPDDR6.
