The size of NAND flash (8-128M)is always bigger than NOR flash (1-16M); Reading a NOR flash is a little faster than NAND flash; Erasing and Writing a NAND flash is much faster than NOR flash; So NAND flash is more fit for storing data and NOR flash is more fit for storing code. And there is ECC (error correction) in NAND flash. You can access NOR flash with SRAM interface and you have to do it with I/O port to NAND flash. Those are some of the differences between NAND and NOR flash.
