Kioxia Corporation, a world leader in memory solutions, today announced sampling of the industry's first Universal Flash Storage (UFS) Ver. 4.0 embedded flash memory devices designed for automotive applications. These new, higher performing devices deliver fast embedded storage transfer speeds in a small package size and are targeted to a variety of next-generation automotive applications, including telematics, infotainment systems and ADAS. The improved performance] of UFS products from Kioxia - including approximately +100% for sequential read speed and approximately +40% for sequential write speed - enables these applications to take advantage of 5G's connectivity benefits, leading to faster system startup times and a better user experience.

The first to introduce UFS technology, Kioxia continues to move the technology forward. Its new UFS Ver. 4.0 devices integrate the company's innovative BiCS FLASH 3D flash memory and a controller in a JEDEC-standard package. UFS 4.0 incorporates MIPI M-PHY 5.0 and UniPro 2.0 and supports theoretical interface speeds of up to 23.2 Gbps per lane or 46.4 Gbps per device. UFS 4.0 is backward compatible with UFS 3.1.



The new Kioxia devices support High Speed Link Startup Sequence (HS-LSS) features, enabling Link Startup (M-PHY and UniPro initialization sequence) between device and host to be performed at a faster HS-G1 Rate A (1248 megabits per second) than that of conventional UFS. This is expected to reduce the time for Link Startup by approximately 70% compared to the conventional method.

Advanced features and functionalities are supported in the new UFS Ver. 4.0 devices to address demanding automotive application requirements, including:
  • Refresh Feature: Improves data reliability by refreshing degraded data to prevent data corruption even in the harsh, demanding in-vehicle environment.
  • Extended Diagnosis Feature: Enables users to view important information from the UFS device, allowing preventative action to be taken.
  • Available in capacities of 128, 256 and 512 gigabytes (GB), the new Kioxia devices support a wide temperature range, meet AEC-Q100 Grade 2 requirements and offer enhanced reliability capabilities that complex automotive applications require.

Anddd we will see this technology implemented in vehicles in 2035...ok maybe 2026 for Tesla...2035 for all others... Excluding Tesla/Rivian/Polesar/a few others, it seems like actual tech of vehicles is sooo slow to market...
