Toshiba Expands Lineup of Embedded NAND Flash Memory Products for Automotive Applications

Supports AEC-Q100 Grade2 Requirements

IRVINE, Calif., Dec. 20, 2016 — (PRNewswire) —   Toshiba America Electronic Components, Inc. (TAEC)* today announced the launch of JEDEC®[1] e-MMCTM Version 5.1[2]-compliant embedded NAND flash memory products supporting AEC-Q100 Grade2 [3] requirements. The new product lineup consists of densities of 8 gigabyte (GB), 16GB, 32GB and 64GB, and is well suited to the demanding requirements of the automotive infotainment market.

As consumer demand for connected cars grows, the need to support the data storage demands of increasingly complex automotive applications – for example, ADAS [4] and autonomous driving systems – grows as well. Toshiba is meeting this demand by reinforcing its lineup of high-performance, high-density memory products.

In the automotive market, the development of car infotainment – ADAS and autonomous driving systems – has created an increased demand for NAND flash memory. Accelerated processing power and increased data storage capacity are crucial to enabling these new technologies, and Toshiba's e-MMC has emerged as the data storage technology of choice for automotive applications.

Toshiba's e-MMC parts integrate NAND chips and are fabricated using its 15nm process technology with a controller to manage basic control functions for NAND applications in a single package. The new products enhance Toshiba's existing lineup of automotive e-MMC devices by offering support for applications such as instrument clusters, which require storage solutions that operate at higher temperatures (up to 105°C).

[5] "BKOPS control" is a function where the host allows the device to perform background operation when the device is idle. "Cache Barrier" is a function that controls when cache data is written to the memory chip. "Cache Flushing Report" is a function that informs the host if the device's flushing policy is FIFO (First In First Out) or not. "Large RPMB write" is a function that enhances the data size that can be written to the RPMB area to 8KB.
[6] Universal Flash Storage: Product category for a class of embedded memory products built to the JEDEC Standard specification.

*The products are labeled based on the memory chip(s) it contains, not the amount of memory capacity available for data storage by the end user. Part of the capacity is reserved for device management. Please refer to the data sheet or your local Toshiba sales representative. (For purposes of measuring memory capacity in this context, 1GB = 1,073,741,824 bytes).

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.
