WebJul 23, 2024 · The typical block size available today ranges from 8KB to 32KB for NAND Flash and 64KB to 256KB for NOR Flash. Erase operations in NAND Flash are straightforward while in NOR Flash, each byte needs to be written with ‘0’ before it can be erased. This makes the erase operation for NOR Flash much slower than for NAND Flash.
