Toshiba Unveils Embedded NAND Flash Memory Products

News

Toshiba has announced that it has begun shipping samples of
embedded NAND flash memory products for automotive applications that are
compliant with JEDEC UFS[1] version 2.1[2]. The new products meet AEC-Q100
Grade2[3] requirements and support a wide temperature range of -40°C to +105°C,
offering the enhanced reliability capabilities that are required by
increasingly complex automotive applications. The line-up meets a broad range
of applications requirements with five different capacities: 16GB, 32GB, 64GB,
128GB and 256GB. [4]

The new products are embedded NAND flash memory products
that integrate NAND chips fabricated with 15nm process technology and a
controller in a single package. Storage requirements for automotive
applications continue to increase as systems including automotive information
& entertainment systems and ADAS[5] become more sophisticated, and UFS
supports their high performance and density needs. The addition of automotive
UFS expands Toshiba Memory Corporation's line-up of embedded NAND flash memory
products for automotive applications, which currently includes automotive
e-MMC[6] products. Utilizing the UFS interface allows the new products to achieve
sequential read of 850MB/s and random read of 50kIOPs, which are approximately
2.7 times and 7.1 times faster than their current e-MMC counterparts,
respectively.[7]

Other new functions specifically suited to automotive
applications have been added to the new UFS products, including Refresh,
Thermal Control and Extended Diagnosis. Refresh can be used to refresh data
stored in the UFS and can contribute to the extension of the data's life span.
Thermal Control protects against overheating in the high temperatures that can
occur in automotive applications. Extended Diagnosis helps users to understand
the condition of the product.

Toshiba Memory Corporation's UFS products have been used to
boost overall system performance in mobile devices, and the introduction of
automotive UFS products is expected to have a similarly positive impact on the
development of automotive information & entertainment systems and ADAS.
Toshiba Memory Corporation is already in discussion with major automobile
makers on the possibility of implementing the new line-up in next-generation
projects. As the storage requirements for automotive applications continue to
grow, Toshiba Memory Corporation will continue to lead the market by
reinforcing its lineup of high-performance, high-density memory solutions
targeting the sector.
