Toshiba enhances its NAND flash portfolio

Integrates error management into the NAND package

By CBR Staff Writer

Toshiba has enhanced its NAND flash portfolio with the introduction of next-gen 24-nanometer (nm) generation ‘SmartNAND,’ which integrate error management into the NAND package.

The new chips will support simplified host-side design and application of advanced NAND process generation in consumer apps, including digital audio players, tablet PCs, information equipment, digital TVs, set-top boxes and other apps that require high-density, non-volatile memory.

The SmartNAND series packages integrate 24nm process NAND flash technology with a control chip supporting error correction code (ECC).

The five devices in the line-up range from 4 to 64 gigabyte (GB) capacities, and are designed to remove the burden of ECC from the host processor while minimising protocol changes; and are targeted for portable media players, tablet PCs and other consumer digital products.

The company said that the new 24nm product line-up will replace current 32nm generation devices, and its advanced process combined with faster controller and internal interface will realise faster read and write speeds and enhance overall performance.

The new offering features include: integrated error correction (ECC); read and write speeds to vary optimised speed performance; and utilises a standard raw NAND interface, for easy replacement of standard NAND.
