WebQuoting from expert. " NOR flash must be erased and written in blocks, but for read access it can be treated just like an async memory attached to the memory interface. So it needs address lines equivalent to its memory size. For NAND flash, everything must be done in terms of pages/blocks (reads/writes can happen on smaller pages, erases still ...
