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



Toshiba America Electronic Components launched a JEDEC e-MMC Version 5.1-compliant embedded NAND flash memory products supporting AEC-Q100 Grade2 requirements. The product line consists of densities of 8 gigabyte (GB), 16GB, 32GB and 64GB. It is designed for the demanding 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 and autonomous driving systems – grows as well.
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).
