Tokyo – The next generation of automotive systems are hungry for more. More advanced information & entertainment and ADAS[2] systems. More storage for event data recording. Support for more 3D mapping. In a move that makes ‘more’ a reality, KIOXIA Corporation today announced that it has begun sampling the industry’s first 512 gigabyte (GB) Automotive Universal Flash Storage[3] (UFS) JEDEC® Version 2.1 embedded memory solution. KIOXIA’s Automotive UFS supports a wide temperature range (-40°C to +105°C), meets AEC-Q100 Grade2[4] requirements and offers the extended reliability required by various automotive applications. The 512GB device joins the company’s existing lineup of Automotive UFS, which includes capacities of 16GB, 32GB, 64GB, 128GB and 256GB.

Innovations such as autonomous vehicles, more advanced automotive information & entertainment systems, digital clusters, telematics and ADAS provide not only an elevated driver experience but also a greater demand for storage within vehicles.

To meet this demand for large capacity memory, KIOXIA’s new 512GB Automotive UFS memory was developed, which integrates the company’s BiCS FLASH™ 3D flash memory and a controller in a single package. 512GB Automotive UFS features several functions well-suited to the requirements of automotive applications including "Refresh", "Thermal Control" and "Extended Diagnosis". The "Refresh" function can be used to refresh data stored in UFS and helps extend the data’s lifespan. The "Thermal Control" function protects the device from overheating in the high-temperature circumstances that can occur in automotive applications. Lastly, the "Extended Diagnosis" function helps the host processor easily understand the device’s status.
