Kioxia / former Toshiba Memory Corporation has just announced the expansion of its portfolio of embedded USF storage products. Based on the company’s BiCS 3D TLC NAND flash memory with a maximum capacity of 512GB, it adapts to a wide operating temperature range with enhanced reliability and durability. In addition, the Kioxia eUFS 512GB in-vehicle memory uses the company’s specially developed master and conforms to the UFS 2.1 HS-G3 specification.

The memory chip can use two full-duplex HS-Gear3 channels with a data transfer rate of 5.8 GT/s per channel, which means a maximum theoretical bandwidth of 1200 MB/s (assuming PSLCD caching and other methods).
In addition, the Kioxia in-vehicle eUFS 2.1 series includes a wide range of model sizes from 16 to 256GB and meets the AEC-Q100 Class 2 standard for long-term operation at extreme temperatures of -40 to 105 degrees C.
It’s worth noting that Kioxia also provides refresh, thermal control, and extended diagnostics for these memory quotas to further improve overall reliability and durability.
Kioxia has now started trialling its in-vehicle eUFS 2.1 512 GB memory with some customers, and the commercial version is expected to be shipped by 2020.
