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 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.
