WebMay 20, 2024 · nand flash内部电路更简单,因此数据密度大,体积小,成本也低。因此大容量的flash都是nand型的。小容量的2~12M的flash多是nor型的。使用寿命上,nand flash的擦除次数是nor的数倍。而且nand flash可以标记坏块,从而使软件跳过坏块。nor flash 一旦损坏便无法再用。 Webstoring the variable data is the Flash memory. The disadvantage of the Flash memory is that it cannot be erased or written in single bytes, as is typically done for EEPROM memory. Flash memory can only be erased and written in large blocks. A typical erase block size may be 256 to 8192 bytes, and a typical write block is 64 to 512 bytes. Some Flash
