Kioxia’s UFS proof of concept (PoC) device is a 512 gigabyte prototype that utilizes the company’s 1 terabit (128 gigabyte) BiCS FLASH™ 3D flash memory with QLC technology, and is now sampling to OEM customers. The PoC device is designed to meet the increasing performance and density requirements of mobile applications driven by higher resolution images, 5G networks, 4K plus video and the like.
 Universal Flash Storage (UFS) is a product category for a class of embedded memory products built to the JEDEC UFS standard specification. UFS uses a serial interface having an advantage of full duplex and simultaneous communication of read/write with its host device.
The samples are POC devices under development and have some feature limitations. Furthermore, specifications of the devices are subject to change without prior notice.
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.
All company names, product names and service names may be trademarks of their respective companies.
Kioxia is a world leader in memory solutions, dedicated to the development, production and sale of flash memory and solid-state drives (SSDs). In April 2017, its predecessor Toshiba Memory was spun off from Toshiba Corporation, the company that invented NAND flash memory in 1987. Kioxia is committed to uplifting the world with “memory” by offering products, services and systems that create choice for customers and memory-based value for society. Kioxia's innovative 3D flash memory technology, BiCS FLASH™, is shaping the future of storage in high-density applications, including advanced smartphones, PCs, SSDs, automotive and data centers.
