KUALA LUMPUR, Jan 30 (Bernama) -- Kioxia Corporation, a world leader in memory solutions, has announced sampling of the industry’s first Universal Flash Storage (UFS) Version (Ver.) 4.0 embedded flash memory devices designed for automotive applications.

According to Kioxia in a statement, 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 advanced driving assistant system (ADAS).

The improved performance of UFS products from Kioxia, enables these applications to take advantage of 5G’s connectivity benefits, leading to faster system startup times and a better user experience.

Kioxia was the first to introduce UFS technology, and its new UFS Ver. 4.0 devices integrate the company’s innovative BiCS FLASH 3D flash memory and a controller in a Joint Electron Device Engineering Council (JEDEC)-standard package.

This version incorporates MIPI M-PHY 5.0 and UniPro 2.0 and supports theoretical interface speeds of up to 23.2 gigabits per second (Gbp/s) per lane or 46.4 Gbp/s per device and 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 initialisation 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 per cent compared to the conventional method.

Advanced features and functionalities are supported in the new version to address demanding automotive application requirements, including improves data reliability by refreshing degraded data to prevent data corruption and enables users to view important information from the UFS device.

Available in capacities of 128, 256 and 512 gigabytes (GB), the new Kioxia devices support a wide temperature range, meet Automotive Electronics Council (AEC)-Q100 Grade2 requirements and offer enhanced reliability capabilities that complex automotive applications require.
