A method according to an embodiment of the present disclosure comprising: receiving a read instruction transmitted by a host device, the read instruction including a first address; reading first data together with a first CRC code and a first ECC which are associated with the first data from a memory based on the first address; and performing error detection on the first data based on the first CRC code, and performing error correction on the first data based on the first ECC if an error is detected. With the embodiments of the disclosure, the CRC code with better capability of error detection is adopted to perform error detection on the data. If any error is detected, error correction is performed using the ECC. Thus, it is possible to overcome the problem as to insufficient capability of error detection of the ECC in the prior art, thereby improving the system performance. |
