Abstract
A semiconductor device includes a latch circuit and a code comparison circuit. The latch circuit latches an output code generated based on an active command. The latch circuit outputs the latched output code as a latch code in response to a write command. The code comparison circuit compares the latch code with a write code to generate a detection signal.
