Micron Technology believes that its ClearNAND high-capacity flash memories will lengthen the life of NAND. Error management techniques are integrated into the NAND package, extending the opportunities for more advanced NAND process generations to be used in enterprise servers, tablet PCs, portable media players, and consumer applications. The memories use a traditional raw NAND interface, and include new features optimised for high-capacity and high-performance applications. As the industry progresses past 20nm, flash management becomes more challenging because the amount of bit errors increases dramatically, impacting performance and reliability. The devices are first designed using its 25nm MLC (multi-level cell) process, and are available in standard and enhanced versions. The standard products come in 8 to 32Gbyte packages, and are intended to remove the error correction code burden from the host processor with minimal protocol changes compared to raw NAND. It is targeted at portable media players and other consumer electronic devices. The enhanced devices, in addition to removing the error correction code from the host processor, also provide enterprise-specific features to enable high-capacity designs. Capacities are available in 16 to 64Gbyte packages and allow 25nm MLC NAND to be used in these applications for the first time. Both standard and enhanced versions are available now.
