KIOXIA America has 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 small package sizes 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 over 100% for sequential read and approximately over 40% for sequential write – enables these applications to take advantage of 5G’s connectivity benefits, leading to faster system startup times and a better user experience.
KIOXIA’s new UFS Ver. 4.0 devices integrate the company’s innovative BiCS FLASH 3D flash memory and a controller in a JEDEC (Joint Electron Device Engineering Council)-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 gigabits per second (Gbp/s) per lane or 46.4 Gbp/s 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 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% compared to the conventional method.
“KIOXIA continues to demonstrate its leadership in UFS memory with the introduction of the industry’s first UFS Ver. 4.0 device for automotive applications,” said Maitry Dholakia, a vice president of memory business unit at KIOXIA America. “The accelerated processing power and increased data storage capacity it provides will enable the next generation of automotive systems that can that take advantage of 5G, IoT and artificial intelligence.”
New, advanced features and functionalities have been included in UFS Ver. 4.0 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: This 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, and meet AEC-Q100 Grade2 requirements. It also offers enhanced reliability capabilities that complex automotive applications require.
