    ii)NAND:.NAND is the 2nd type of flash . It has faster erase and write times, and requires a smaller chip area per cell .Tt also has up to ten times the endurance of NOR flash. However, the I/O interface of NAND flash does not provide a random-access external address bus. Rather, data must be read on a block-wise basis, with typical block sizes of hundreds to thousands of bits.
