For example, a semiconductor device includes latch circuits, whose input nodes are connected to an input selection circuit and whose output nodes are connected to an output selection circuit; and a control circuit, which controls the input selection circuit and the output selection circuit. The control circuit includes a shift register to generate an input pointer signal and a binary counter to generate an output pointer signal. The input selection circuit selects one of the latch circuits on the basis of a value of the input pointer signal. The output selection circuit selects one of the latch circuits on the basis of a value of the output pointer signal. Therefore, it is possible to prevent a hazard from occurring in the input selection circuit, as well as to reduce the number of signal lines that transmit the output pointer signal.
