ClearNAND A New Way For Advanced NAND Solutions

With NAND flash becoming the primary storage medium for manufacturers of wireless, consumer and enterprise computing devices.Micron release a new flash memory device ClearNAND which extend the life og NAND.ClearNAND products incorporate NAND error correction intelligence and paving the way for further NAND technology scaling.ClearNAND integrates a controller and NAND die in an MCP and it manages the required ECC enables easy migration and in the case of Enhanced ClearNAND Flash……

Micron Technology, Inc. today introduced a portfolio of high-capacity flash memory products that will lengthen the life of NAND for years to come.By integrating the error management techniques in the same NAND package, the new Micron ClearNAND devices alleviate the challenges traditionally found in NAND process shrinks.Micron’s ClearNAND portfolio extends the opportunities for more advanced NAND process generations to be used in enterprise servers, tablet PCs, portable media players, and dozens of other consumer applications.

Micron’s ClearNAND products utilize a traditional raw NAND interface and include new features that are optimized for high-capacity and high-performance applications.As the industry progresses past 20-nanometer (nm) flash management gets more challenging because the amount of bit errors increases dramatically, impacting NAND performance and reliability.By tightly coupling the error management with the NAND devices in a single package, Micron’s customers can continue to take advantage of the highest capacity and lowest cost-per-bit flash memory solution. Micron’s ClearNAND products are first designed using its 25nm multi-level cell (MLC) process, and are available in two versions: Standard and Enhanced.

Micron’s Standard ClearNAND products come in 8 to 32 gigabyte (GB) packages and are intended to remove the error correction code (ECC) burden from the host processor with minimal protocol changes compared to raw NAND.The Standard ClearNAND portfolio is targeted for portable media players and other consumer electronic devices.Micron’s Enhanced ClearNAND products, in addition to removing the ECC burden from the host processor.Also provide new enterprise specific features to enable high-capacity designs, delivering improved performance and reliability.Capacities are available in 16 to 64GB packages. The Enhanced ClearNAND products are targeted at enterprise and computing applications and allows leading-edge 25nm MLC NAND to be used in these applications for the first time.

With wireless, consumer, computing and enterprise manufacturers moving toward NAND flash as their primary storage medium.Most designers require a broad selection of technology solutions to fit a vast array of end-product designs. From tablet PCs to flash-based notebooks to high-end smartphones and data center servers all of these applications are very distinct and call for a different type of NAND flash. The ClearNAND products strengthen Micron’s NAND flash portfolio, providing the company with a broad offering of solid-state storage solutions.
