Clearly, NAND has several significant positive attributes. However, it's not well-suited for direct random access. NOR flash requires around 41 I/O pins for a 16-bit device, while NAND devices requires only 24 pins for a comparable interface.

One limitation of flash memory is that it can be erased only a block at a time. This generally sets all bits in the block to 1. Starting with a freshly erased block, any location within that block can be programmed. However, once a bit has been set to 0, only by erasing the entire block can it be changed back to 1. In other words, flash memory (specifically NOR flash) offers random-access rea…
