Embedded Flash Memory Updates: UFS 3.1– and Beyond

UFS 3.1 and Beyond

Maintaining our leadership position in UFS technology, KIOXIA recently announced two new Universal Flash Storage (UFS) embedded flash memory solutions that support the growing needs of current and future customers.

In January, KIOXIA initiated sampling our 512 gigabyte (GB) QLC UFS PoC devices to OEM customers. These UFS Ver. 3.1 devices, with 4-bit-per-cell, quadruple-level cell (QLC) technology, are targeted to applications needing high density, such as cutting-edge smartphones. The new 512GB PoC devices utilize our 1 Terabit BiCS FLASH™ 3D flash memory with QLC technology.

Following on the heels of that news, KIOXIA kicked off sampling of the industry’s first1 UFS devices supporting MIPI® M-PHY® v5.0. Utilizing our BiCS FLASH 3D flash memory, the new devices are available in three capacities: 128GB, 256GB and 512GB. The new devices deliver high speed read and write performance and are targeted to mobile applications.

Our latest news releases have all the details:



KIOXIA has been at the forefront of UFS memory innovation since 2013, when we were the first to sample the technology2. We’ll continue to bolster our leadership position by providing flash memory solutions that enhance the capabilities of the many applications that use UFS.

Read and write speed may vary depending on the host device, read and write conditions, and file size.

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. For details, please refer to applicable product specifications. The definition of 1KB = 2^10 bytes = 1,024 bytes. The definition of 1Gb = 2^30 bits = 1,073,741,824 bits. The definition of 1GB = 2^30 bytes = 1,073,741,824 bytes. 1Tb = 2^40 bits = 1,099,511,627,776 bits.
