Kioxia Sampling UFS 5.0 Embedded Flash Memory Devices, Achieving Approximately 10.8GB/s Effective Read/Write Performance with 2 Lanes

Kioxia announced today on its official website that it has begun sampling UFS 5.0 embedded flash memory for next-generation mobile applications. 

UFS 5.0 is a new standard for embedded flash storage currently being developed by JEDEC to meet the performance requirements of next-generation mobile devices such as high-end smartphones equipped with on-device AI functions. It utilizes MIPI M-PHY version 6.0 for the physical layer and UniPro version 3.0 for the protocol. M-PHY version 6.0 introduces the new HS-GEAR6 mode, theoretically supporting an interface speed of up to 46.6 Gbps per lane; with 2 lanes, UFS 5.0 can achieve approximately 10.8 GB/s of effective read/write performance.

The evaluation samples incorporate an in-house newly developed controller for UFS 5.0 and Kioxia’s 8th-generation BiCS FLASH™, and are available in capacities of 512 GB and 1 TB. The package has been newly designed with a small 7.5 x 13 mm size, contributing to board space efficiency and design flexibility.

The samples are provided to customers who are developing UFS 5.0-compatible host systems, enabling them to evaluate performance and conduct interoperability testing.

Kioxia will continue to introduce new flash memory technologies into its UFS products to meet the increasing demands for larger capacity and higher performance in the mobile market.
