Toshiba introduces new embedded-NAND flash memory with ECC function in 24nm

Toshiba Corporation has introduced 24-nanometer (nm) generation "SmartNAND," which integrate error management function into the NAND package. The new chips will support simplified host-side design and application of advanced NAND process generation in consumer applications, including digital audio players, tablet PCs, information equipment, digital TVs, set-top boxes and other applications that require high-density, non-volatile memory.

Samples of the new SmartNAND line-up will be available from middle of April, and mass production will start in the second quarter of CY2011 (April to June).

The SmartNAND series packed with a control chip supporting error correction code (ECC). The five devices in the latest line-up range from 4 to 64 gigabyte (GB) capacities, and are expressly designed to remove the burden of ECC from the host processor while minimizing protocol changes.

The new 24nm product line-up will replace current 32nm generation devices, and its advanced process combined with faster controller and internal interface will realize faster read and write speeds and enhance overall performance. SmartNAND also supports a range of read and write speeds, optimized to suit design objectives, and four read modes and two write modes will be offered.
