Abstract
A semiconductor device includes a control circuit configured to generate an input enable signal, an output enable signal, a latch control signal, and an error correction control signal based on a write control signal, a write check command, and a read check command for performing an error correction test mode; a latch circuit configured to generate latch data, a latch parity, and a latch masking signal by latching input data, an input parity, and an input masking signal and configured to re-store corrected data as the latch data, during a period in which the latch control signal is enabled; and an error correction circuit configured to generate the corrected data by correcting an error, included in the latch data, based on the latch data, the latch parity and the latch masking signal during a period in which the error correction control signal is enabled.
