A semiconductor memory device includes a data coding logic for generating converted data groups and a inverted flag data from original data groups received by the semiconductor memory device. The number of zeros in the converted data groups is less than or equal to the number of zeros in the original data groups. The semiconductor memory device also includes data decoding logic for generating the original data groups from the converted data groups and the inverted flag data. A peripheral circuit may be enabled to program the converted data groups and the inverted flag data into the memory cells and read the converted data groups and the inverted flag data from the memory cells. A control logic may be enabled to generate control signals for the data coding logic, the data decoding logic, and the peripheral circuit.
