CXMT Nears End of LPDDR6 R&D Validation, Aiming for World's First Mass Production in Second Half

China's 'Times Weekly' reported on Saturday (April 1), citing sources, that ChangXin Memory Technologies (CXMT) has nearly completed the R&D validation phase for LPDDR6, bringing it one step closer to being the first to mass-produce the next-generation mobile memory.

The introduction of LPDDR products typically involves four key milestones: standalone chip verification, R&D validation, small-batch integration testing, and finally mass production. This means that before a mobile memory chip is officially deployed in end devices, it must pass through several rigorous testing phases.

R&D validation includes compatibility testing, system stability verification, performance and power consumption evaluation, and mechanical reliability testing. These comprehensive assessments ensure the product's design is both rational and reliable, allowing potential risks to be identified early.

The report notes that as early as March 2024, industry sources in China indicated CXMT was actively pushing for LPDDR6 commercialization, having already sent samples to key customers, with plans to achieve the world's first mass production launch in the second half of 2024.

According to available information, CXMT's first LPDDR6 product is designed with a data rate of 12,800 Mbps, with a base operating speed of 10,667 Mbps when working in tandem with SoCs. The die capacity is 16Gb, resulting in a 16GB chip package, using a 1295-ball PoP (Package on Package) configuration. The product features significant improvements in power efficiency and RAS (Reliability, Availability, and Serviceability) functions compared to LPDDR5X.
