Abstract
Semiconductor memory device may include a memory cell array, an error correction circuit, an input/output (I/O) gating circuit and a control logic circuit. The control logic circuit may, in a first write operation mode, control the I/O gating circuit to select a sub-page, read a first unit of data including a first sub unit of data, a second sub unit of data and a first parity data from the sub-page, and provide the first unit of data to the error correction circuit. The control logic circuit may also control the error correction circuit to perform an error-correcting code decoding on the first unit of data to generate syndrome data, generate second parity data based on a portion of the first unit of data and generate third parity data based on a write parity data, the second parity data and the syndrome data.
