Initial Market Launch

Xiaomi is the first customer for these LPDDR6 modules, which will be used in the Xiaomi 18 Fold. Since the device’s market launch is scheduled for September, shipments of the memory modules are already underway. Beyond the initial launch with Xiaomi, the manufacturer has confirmed a broad customer list that includes Lenovo, Honor, Vivo, Oppo, and Transsion, as well as enterprise customers such as Alibaba Cloud, ByteDance, and Tencent.

Technical Specifications and Performance Metrics

The first generation of LPDDR6 produced by CXMT offers a base speed of 10.7 Gbit/s, with a peak operating speed of 12.8 Gbit/s. This represents a technical advancement over LPDDR5X, which reached a maximum of 10.7 Gbit/s under extreme overclocking conditions.

The hardware specifications for these modules include:

  • Capacity: 16 Gb (equivalent to 2 GB).
  • Package: Package-on-Package (POP) package.
  • Architecture: Ball Grid Array with approximately 1,295 pins.

Competitive Landscape and Industry Standards

SK hynix is also nearing the mass production phase for LPDDR6. The South Korean company has announced that its modules will utilize the sixth-generation 1c node in the 10-nm process. While SK hynix is aiming for higher potential speeds of up to 14.4 Gbit/s with a capacity of 16 Gb, both manufacturers are operating within the official specifications defined by JEDEC.
