Abstract: A memory device includes an ECC circuit that performs error correction code (ECC) encoding on input data to generate write data, and a memory cell array including a plurality of memory cells that stores the write data. The ECC circuit includes a data splitter that splits the input data into first sub-data and second sub-data, a first ECC encoder that performs ECC encoding on the first sub-data to generate first sub-parity data, a second ECC encoder that performs ECC encoding on the second sub-data to generate second sub-parity data, and a data scrambler that performs a data scrambling operation with respect to the first sub-data, the second sub-data, the first sub-parity data, and the second sub-parity data based on a structure of the memory cell array to generate the write data.
