Kioxia Developed UFS V3.1 Embedded Flash Memory Devices With 4-Bit QLC Technology

Kioxia Europe GmbH announced the Universal Flash Storage (UFS) Ver. 3.1 ^[1] embedded flash memory devices utilizing the company’s 4-bit QLC technology.

For applications needing high density, such as cutting-edge smartphones, the QLC technology enables the capability to achieve the highest densities available in a single package.

The firm’s UFS PoC device is a 512GB prototype that utilizes the company’s one terabit (128GB) BiCS flash 3D flash memory with QLC technology. It 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.

“Kioxia has been an inventor and leading supplier of UFS memory since 2013. Since that time, we focus on expanding our already broad lineup with new UFS Memory products for applications that demand superior interface performance,” noted Axel Stoermann, VP, memory marketing and engineering. “With QLC UFS we can offer another solution which will meet the increasing requirements for flash memory devices,” he continues.

The company is sampling its 512GB QLC UFS PoC devices to select OEM customers.

The samples are POC devices under development and have some feature limitations. Furthermore, specs of the devices are subject to change.

^[1] Universal flash Storage (UFS) is a product category for a class of embedded memory products built to the JEDEC UFS standard spec. UFS uses a serial interface having an advantage of full duplex and simultaneous communication of R/W with its host device.
