applying a read command to a memory device, the read command pointing to address information, reading to-be-read data from a storage cell corresponding to the address information to which the read command points, and storing the address information to which the read command points in a preset storage space if an error occurs in the to-be-read data; and
applying a write command to the memory device, comparing address information to which the write command points with the address information stored in the preset storage space, executing a write operation on a storage cell corresponding to the address information to which the write command points if the address information to which the write command points is not the same as the address information stored in the preset storage space, and stopping the write operation on the storage cell corresponding to the address information to which the write command points if the address information to which the write command points is the same as the address information stored in the preset storage space.
