nor flash 与 nand flash 的区别
Beside the different silicon cell design, the most important difference between NAND and NOR Flash is the bus interface. NOR Flash is connected to a address / data bus direct like other memory devices as SRAM etc. NAND Flash uses a multiplexed I/O Interface with some additional control pins. NAND flash is a sequential access device appropriate for mass storage applications, while NOR flash is a random access device appropriate for code storage application.NOR Flash can be used for code storage and code execution. Code stored on NAND Flash can't be executed frome there. It must be loaded into RAM memory and executed from there.
