Start Your Engines: Automotive UFS 4.0 Has Arrived

Start Your Engines Automotive UFS 4 Has Arrived

In yet another industry first1, KIOXIA is now sampling2 Universal Flash Storage3 (UFS) Ver. 4.0 embedded flash memory devices for automotive applications. This technological leap from UFS Ver. 3.1 to 4.0 elevates the performance of next-generation automotive systems, including telematics, infotainment systems, and Advanced Driver Assistance Systems (ADAS).

The accelerated processing power4 and increased data storage capacity4 provided by our new devices will allow automotive systems to take advantage of 5G, IoT, and artificial intelligence.

KIOXIA has established itself as a pioneer in UFS technology, and our new UFS Ver. 4.0 devices continue to push the boundaries by integrating our innovative BiCS FLASH™ 3D flash memory and a controller in a JEDEC-standard package. The UFS 4.0 technology incorporates MIPI® M-PHY® 5.0 and UniPro® 2.0, supporting theoretical interface speeds of up to 23.2 gigabits per second (Gbp/s) per lane or 46.4 Gbp/s per device, while maintaining backward compatibility with UFS 3.1.

The new KIOXIA devices are available in capacities of 128, 256, and 512 gigabytes, support a wide temperature range, meet AEC-Q100 Grade25 requirements, and offer enhanced reliability capabilities that complex automotive applications require.

As the automotive industry continues to evolve, cutting-edge UFS Ver. 4.0 devices from KIOXIA are poised to play a pivotal role in shaping the future of in-vehicle experiences. Check out our latest press release for all of the details – and be sure to visit our new Automotive UFS 4.0 Microsite dedicated to flash storage that moves the automotive industry forward.

1: As of January 29, 2024

2: Sample shipments will begin this month. Specification of the samples may differ from commercial products.

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: Compared to previous generation devices

5: 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.
