Performance Improvements Fuel Evolution of Automotive Applications; Elevate Driver Experience

SAN JOSE, Calif.: KIOXIA America, Inc. today announced sampling1 of the industry’s first2 Universal Flash Storage3 (UFS) Ver. 4.0 embedded flash memory devices3 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 ADAS4. The improved performance5 of UFS products from KIOXIA – including approximately +100% for sequential read and approximately +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.

The first to introduce UFS technology6, 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 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 initialization sequence) between device and host to be performed at a faster HS-G1 Rate A (1248 megabits per second7) than that of conventional UFS. This is expected to reduce the time for Link Startup by approximately 70% compared to the conventional method.

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: 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 AEC8-Q100 Grade2 requirements and offer enhanced reliability capabilities that complex automotive applications require.

“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, vice president, Memory Business Unit, for KIOXIA America, Inc. “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.”

Notes:

1: Sample shipments will begin this month. Specification of the samples may differ from commercial products.
2: As of January 29, 2024
3: Universal Flash Storage (UFS) is a product category for a class of embedded memory products built to the JEDEC UFS standard specification. Due to its serial interface, UFS supports full duplexing, which enables both concurrent reading and writing between the host processor and UFS device.
4: Advanced Driving Assistant System
5: Compared to previous generation devices
6: Source: KIOXIA Corporation, as of February 2013.
7: PWM-G1 communication speed depends on the host and the device.
8: Electrical component qualification requirements defined by the AEC (Automotive Electronics Council).

Read and write speeds are the best values obtained in a specific test environment at KIOXIA and KIOXIA warrants neither read nor write speeds in individual devices. Read and write speed may vary depending on device used and file size read or written.

In every mention of a KIOXIA product: Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application. For details, please refer to applicable product specifications. The definition of 1KB = 2^10 bytes = 1,024 bytes. The definition of 1Gb = 2^30 bits = 1,073,741,824 bits. The definition of 1GB = 2^30 bytes = 1,073,741,824 bytes. 1Tb = 2^40 bits = 1,099,511,627,776 bits.
