    • A NAND flash memory device performing an error detecting and data reloading operation during a copy back program operation is provided. The device includes a cell array having a plurality of planes and a parity cell array having a plurality of parity planes. Each of the parity planes stores a parity of each of the planes. Additionally, the device includes a parity generating and parity column selecting circuit generating a new parity about reloaded data from an outside during a copy back program operation, and storing the new parity on a parity plane corresponding to a plane on which the reloaded data is stored.
    • 提供了在复制回程序操作期间执行错误检测和数据重新加载操作的NAND快闪存储器件。 该装置包括具有多个平面的单元阵列和具有多个奇偶校验平面的奇偶校验单元阵列。 每个奇偶校验平面存储每个平面的奇偶校验。 此外,该装置包括奇偶校验生成和奇偶校验列选择电路,其在复制回程序操作期间从外部产生关于重新加载的数据的新奇偶校验,并将新奇偶校验存储在对应于其上存储有重载数据的平面的奇偶校验平面上 。
