Toshiba 32GB Embedded NAND flash memory devices

Toshiba announced today the launch of the largest density NAND products, embedded flash memory devices of 32GB, which also feature full compliance with the eMMC and eSD standards. The

new devices are designed for use in digital consumer products like mobile phones, video cameras, HDTV, personal navigation devices, POS terminals, printers, and set-top boxes. The company announced that it would make available samples of the devices in September, and that it would start mass producing them in the fourth quarter of the year.

Each of the new embedded devices includes eight 32Gbit (= 4GB) NAND chips fabricated under Toshiba's cutting-edge 43nm process technology, and also has an integrated dedicated controller. The devices support standard interfacing and simplified embedding in products, as they feature full compliance with JEDEC/MMCA Ver. 4.3 and SDA Ver. 2.0 high-speed memory standards defined by the MultiMediaCard Association and SD Card Association for memory cards.

The company makes available a series of single-package embedded NAND Flash memories that feature a controller designed to manage basic control functions for NAND applications: LBA-NAND memory, which has a NAND interface; eSD large capacity chips with SD interface; and e MMC with an HS-MMC interface. Applications for a very wide range of products are supported by this line-up, which comes in densities ranging from 1GB to 32GB.

One of the key features of the new line-up is the integrated controller, which can handle essential functions like writing block management, error correction (ECC) and driver software. It is also meant to ensure improved time to market for future upgraded products. Another important feature is the fact that up to 560 hours of data recording at a bit rate of 128Kbps is available on the 32GB device. It can also record up to 7.3 hours of standard definition video 4.

A controller function designed to minimize development requirements and to ease integration into system designs is what today's industry is looking for. As this segment of the market is expanding, Toshiba has been walking towards securing its leadership in the area, and the development of other high or higher density modules will assure its position.
