Toshiba - Embedded NAND flash memory in 24nm process
Toshiba Electronics Europe (TEE) has enhanced its NAND flash portfolio with the introduction of SmartNAND, its next-generation 24-nanometer (nm) NAND flash product family. The SmartNAND series integrates leading-edge 24nm process NAND flash technology with a control chip that supports error correction code (ECC) and is available in densities ranging from 4 to 64 gigabytes (GB)(1).
The SmartNAND simplifies the host-side design and application of advanced NAND technology in a range of applications including portable media players, tablet PCs, digital TVs, set-top-boxes and other devices that require high-density, non-volatile memory.
By enabling the system designer to directly manage the NAND using a standard or custom host NAND controller, while leaving the function of error correction within the NAND package, SmartNAND results in faster time to market, access to leading geometries and potentially lowers design costs when compared to conventional NAND flash implementations with external ECC.
The new SmartNAND 24nm product lineup is a replacement for current 32nm generation devices. Its advanced process combined with a faster controller and internal interface achieves faster read and write speeds and enhances overall performance. Optimised to suit a variety of design objectives, SmartNAND supports a range of read and write speeds including four read modes and two write modes.
Utilising the long established raw NAND interface, the SmartNAND family includes new features that are optimised for high-capacity and high-performance applications. Managing bit errors is essential so that digital products can maintain acceptable levels of performance and reliability. The integration of error management with the NAND device, in a single package, allows Toshiba’s customers to take advantage of high capacity, advanced flash memory solutions that offer excellent error management.
Samples of the new SmartNAND family will be available from the middle of April and mass production will begin in the second quarter of CY2011 (April to June).
