Toshiba introduces new embedded-NAND flash memory in 24nm process

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 packages integrate leading-edge 24nm process NAND flash technology 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 SmartNAND portfolio is targeted for portable media players, tablet PCs and other consumer digital products etc.

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.

The new products utilize the long established raw NAND interface, and include new features that are optimized for high-capacity and high-performance applications. Managing bit errors is essential for digital products to maintain acceptable levels of performance and reliability. Installing error management with the NAND devices in a single package allows Toshiba's customers to take advantage of high capacity, advanced flash memory solutions offering excellent error management.

Demand continues to grow for large density chips that support high resolution video and enhanced storage, particularly for embedded memories with a controller function that minimizes development requirements and eases integration into system designs. Toshiba has established itself as an innovator in this key area, and is now reinforcing its leadership by further enhancing its SmartNAND.

1. The integrated error correction (ECC) and leading edge 24nm process generation allows to bring enhanced speed performance of 1.9 times faster read speed and 1.5 times faster write speed than current line-up.
2. Toshiba's SmartNAND offer range of read and write speeds to vary optimized speed performance; the read speed will be available in four options, and the write speed of two. Power save mode is also available for lower power requests.
3. Toshiba's SmartNAND utilize a standard raw NAND interface, allowing easy replacement of standard NAND. SmartNAND can be applied to existing host controllers, with driver software support if necessary. This simplifies system development, allowing manufacturers to minimize development costs and to improve time to market for new and upgraded products.
