Kioxia Corporation, a world leader in memory solutions, announced sampling[1] of the industry’s first[2] Universal Flash Storage[3] (UFS) embedded flash memory devices supporting MIPI M-PHY[4] v5.0. The new line-up utilizes the company’s BiCS FLASH™ 3D flash memory and will be available in three capacities: 128GB, 256GB and 512GB. With high speed read and write performance, the new devices are targeted to a variety of mobile applications including leading-edge smartphones.

The new devices are next-generation UFS supporting MIPI M-PHY v5.0, which has a theoretical interface speed of up to 23.2Gbps per lane (x2 lanes = 46.4Gpbs) in HS-GEAR5 mode. Sequential read and write performance of the 256GB device are improved by approximately 90 percent and 70 percent respectively, over previous generation devices[5]. Also, random read and write performance of the 256GB device are improved by approximately 35 percent and 60 percent respectively, over previous generation devices[5]. This next generation of UFS provides significant increases in performance, enabling next generation smartphones and other products to enhance their capabilities and end user experiences in the 5G era and beyond.
Read and write speeds are the best values obtained in a specific test environment at Kioxia Corporation and Kioxia Corporation warrant neither read nor write speeds in individual devices. Read and write speed may vary depending on the device used and file size read or written.
In every mention of a Kioxia product: Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application.
