Universal storage flash memory enhances driver experience, says Kioxia
Believed to be the industry’s first 512Gbyte automotive universal flash storage (UFS) device targets advanced infotainment and advanced driver assistance systems (ADAS) and support for 3D mapping demand more storage for event data recording, reports Kioxia Europe (formerly Toshiba Memory Europe).
The company has announced it is sampling the 512Gbyte automotive UFS JEDEC Version 2.1 embedded memory.
It supports a wide temperature range (-40 to +105 degrees C), meets AEC-Q100 Grade 2 requirements and offers extended reliability required by some automotive applications. The 512Gbyte version joins the company’s existing line up of automotive UFS, which includes capacities of 16-, 32-, 64-, 128- and 256Gbytes. (It should be noted that Kioxia identifies product density 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.)
The 512Gbyte automotive UFS memory integrates the company’s BiCS FLASH 3D flash memory and a controller in a single package. It is suitable for automotive applications including refresh, thermal control and extended diagnosis. The refresh function refreshes data stored in UFS and helps extend the data’s lifespan. Thermal control protects the device from over-heating in the high-temperature circumstances that can occur in automotive applications and the extended diagnosis function helps the host processor understand the device’s status.
Kioxia Europe (formerly Toshiba Memory Europe) is the European-based subsidiary of Kioxia, supplier of flash memory and solid state drives (SSDs). From the invention of flash memory to BiCS FLASH 3D technology, for storage in high-density applications, including advanced smartphones, PCs, SSDs, automotive and data centres.
