CXMT's LPDDR6 Enters Risk Production, Mass Production Expected Within Weeks

According to the latest industry developments, memory giant ChangXin Memory Technologies (CXMT) (688825-CN) has officially entered the risk production phase for its LPDDR6 memory project. This advancement signifies that CXMT is striving to close the gap with international memory leaders such as Samsung, SK Hynix, and Micron (MU-US) in terms of chip manufacturing processes and technological evolution.

In terms of product specifications, the transmission speed of CXMT's first batch of LPDDR6 chips reaches 12.8Gbps, surpassing the baseline rate of 10.7Gbps defined by the JEDEC standard.

According to analysis by Chinese media outlet 'Kuaikeji,' compared to LPDDR5X, which can only achieve 10.7Gbps under extreme conditions, the new generation LPDDR6 improves bandwidth performance by approximately 20% under normal operating conditions. The chip has a single capacity of 16Gb (equivalent to 2GB) and adopts PoP (Package-on-Package) technology using a 1295-pin BGA (Ball Grid Array), effectively optimizing internal space layout in mobile devices such as smartphones.

Reports indicate that CXMT is actively providing samples to mainstream smartphone manufacturers and computing platforms for verification. If prototype testing meets expectations, the product is expected to enter mass production within the year. The report notes that thanks to the high efficiency of its capacity construction, the time window from risk production to mass production could be shortened to just a few weeks.

Regarding the competitive landscape, although rivals like SK Hynix have already invested in developing higher-spec products at 14.4Gbps, 'Kuaikeji' believes that CXMT's 12.8Gbps version better aligns with current market demands for practical mass production, representing a more pragmatic development strategy. Furthermore, with the widespread adoption of on-device large AI models, LPDDR6's high-bandwidth capability will help alleviate performance bottlenecks in local AI inference, holding real significance for supply chain security.
