KIOXIA introduces UFS ver. 3.1 embedded memory devices

“The storage requirements for automotive applications continue to increase as infotainment systems and ADAS[3] in cars become more sophisticated.” explains Axel Störmann, Vice President Memory Marketing & Engineering, KIOXIA Europe GmbH. ”UFS is well-suited to support the high-performance and density needs of these applications.” The new devices support a wide temperature range (-40°C to +105°C), meet AEC[4]-Q100 Grade2 requirements and offer enhanced reliability capabilities that increasingly complex automotive applications require.

Both the sequential read and sequential write performance of the Automotive UFS Ver. 3.1 device are significantly improved by approximately 2.2x and 6x, respectively, over previous generation devices[5]. These performance gains contribute to faster system startup and OTA (Over-the-Air) updates. 

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.
