Toshiba America Electronic Components Inc. (TAEC) has developed what it claims as a versatile, multiapplication single level cell (SLC) NAND flash memory with embedded error correction code (ECC). BENAND, TAEC stated, can be used in LCD TVs, digital cameras, robots and other industrial applications that include 2-way radios, thermostats, home gateways, cable boxes, POS systems, smart meters, vending machines, in-flight entertainment systems and LCD advertising systems.

Toshiba's BENAND flash memory combines 4bit per 512B embedded correction code and 32nm process NAND flash memory are embedded in one package. It removes the burden of ECC from the host processor while minimizing protocol changes and allowing host processors to support leading-edge process NAND flash memory in a timely manner, TAEC said. Package and pin configuration compatibility are assured with general SLC NAND flash, allowing for easy replacement in existing products.


Toshiba's BENAND combines 4bit per 512B ECC.

Until now, the ECC has been embedded in the host processor and corrected 1bit per 512B. However, advances in memory process technology require enhanced error correction.

"Toshiba's BENAND enables smooth migration to the latest SLC NAND process technologies," stated�Brian Kumagai, senior business development manager, NAND flash memory products for TAEC. "With its on-board ECC, BENAND provides rapid migration to higher density SLC NAND for long life-cycle applications such as industrial and OEM."

SLC-based BENAND joins Toshiba's family of embedded NAND solutions, available in 4Gb and 8Gb TSOP and BGA packages.

Samples of eight BENAND products in two capacities, 4Gb and 8Gb, are available with mass production beginning�March this year.
