Thank you for contacting Cypress Community Forum. NAND allows 1-bit (or 2-bit, or 4-bit or even more, refers to respective NAND device datasheet) error bits per 512 bytes data. NAND also allows <2% bad blocks of the total number of blocks. So NAND file system not only needs ECC handling, but also needs bad block management.
NOR flash has 0 Bit Error Rate and 0 bad block as far as the working condition meet device specification. So NOR flash file system does not need to handle ECC and bad block management.
