The storage requirements for automotive applications continue to increase as infotainment systems and ADAS³ in cars become more sophisticated. 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 AEC⁴-Q100 Grade2 requirements and offer enhanced reliability capabilities that increasingly complex automotive applications require.

The sequential read and write performance of the Automotive UFS Ver. 3.1 device is significantly improved by approximately 2.2x and 6x respectively, over previous generation devices⁵. These performance gains contribute to faster system startup and OTA (Over-the-Air) updates.

“KIOXIA continues to provide advanced flash memory solutions for automotive with the introduction of this new UFS line-up,” noted Scott Beekman, vice president, Memory Business Unit, for KIOXIA America, Inc. “With the increased performance enabled by version 3.1 UFS devices tailored for automotive, enhanced capabilities in functions, such as ADAS and infotainment systems, can be realized.”

Notes

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.
