IntroductionThe increasing demand for high-speed storage capability both in consumer electronics (e.g., USB flash drives, digital cameras, MP3 players, solid state hard-disks, etc.) and mission critical applications, makes NAND flash memories a rugged, compact alternative to traditional mass-storage devices such as magnetic hard-disks.The NAND flash technology guarantees a non-volatile high-density storage support that is fast, shock-resistant and very power-economic.At higher capacities, however, flash storage can be much more costly than magnetic disks, and some flash products are still in short supply.Furthermore, the continuous downscaling allowed by new technologies introduces serious issues related to yield, reliability, and endurance of these devices (Cooke, 2007;
