Abstract:
A semiconductor memory device includes a memory cell array and an error correction code (ECC) engine. The memory cell array stores bits of normal data and parity data therein. The ECC engine performs a masking operation in a masking mode, the ECC engine calculating the parity data using the normal data. The normal data includes a first section that is to be updated and a second section that is to be saved by the masking operation.
