Abstract:
A storage device is provided which includes an ECC circuit. At a write operation, the ECC circuit generates a CRC (cyclic redundancy check) parity corresponding to data and generates an ECC (error correction code) parity corresponding to the data using an error correction code. At a read operation about the data stored in the at least one nonvolatile memory device, the ECC circuit corrects an error of the data using the CRC parity and the ECC parity.
