A Semiconductor memory apparatus includes: a data latch driving unit configured to latch and drive data and to transfer the driven data via a first data bus, based on a detection start signal and a detection stop signal; a data masking latch driving unit configured to latch and drive a data masking signal and to transfer the driven data masking signal via a second data bus, based on the detection start signal and the detection stop signal; an error detection unit configured to perform an error detection operation on the data and the data masking signal to generate an error detection signal, based on the detection start signal and the detection stop signal; an error detection driving unit configured to drive the error detection signal and to transfer the driven error detection signal via a third data bus; a write control unit configured to generate a write control signal based on the data masking signal transferred via the second data bus and the error detection signal transferred via the third data bus; and a data write unit configured to write aligned data transferred via the first data bus into a core circuit, based on the write control signal.
