NAND Flash arrays are divided into a series of 128kB blocks, which are the smallest erasable entities in a NAND device. To erase a block is to set all bits to "1" (and all bytes to FFh). It is necessary to change the erased bits from "1" to "0" by programming. The smallest programming entity is the byte.
