Kioxia Sampling Evaluation Samples of UFS 5.0 Embedded Flash Memory Devices for Next-Gen Mobile Applications
Available in capacities of 512GB and 1TB, and package has been newly designed with a small 7.5 x 13 mm size
This is a Press Release edited by StorageNewsletter.com on March 10, 2026 at 2:00 pmKioxia Corp. announced that it has begun shipping evaluation samples (1) of embedded flash memory compatible with the next-gen UFS standard, UFS 5.0, which is currently being standardized by JEDEC. (2)
UFS 5.0 is a new standard for embedded flash storage currently being developed by JEDEC to meet the performance requirements of next-gen 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 46.6Gb/s per lane; with 2 lanes, UFS 5.0 can achieve approximately 10.8GB/s of effective RW performance.
The evaluation samples incorporate an in-house newly developed controller for UFS 5.0 and Kioxia’s 8th Gen BiCS FLASH, and are available in capacities of 512GB and 1TB. 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.
(1) These samples are intended for functional evaluation only. Specifications of the samples will differ from commercial products.
(2) Shipments of 512GB evaluation samples began on February 24, and shipments of 1TB samples are scheduled to start from March onwards.
