The disclosed invention is intended to decrease the power consumption of a pulse latch circuit. A pulse latch circuit that operates in sync with a pulsed clock signal, including a first operation mode in which shifting test pattern scan data is performed and a second operation mode in which shifting the test pattern scan data is not performed, comprises the following circuits: a first latch circuit that is able to latch input data in sync with the clock signal; a second latch circuit that is connected to the first latch circuit and is able to latch the test pattern scan data to be shifted in sync with the clock signal; and a control circuit that stops supply of the clock signal to the second latch circuit during the second operation mode. By thus stopping the supply of the clock signal to the second latch circuit, decrease the power consumption is achieved.

A selector circuit precisely outputs a signal selected from a plurality of signals. A latch circuit unit generates an internal selection control signal for controlling a selection operation of a selector circuit unit. When the levels of first and second data input signals do not match each other, the selector circuit unit maintains its selected state and does not perform a selecting operation based on the selection signal until the levels of the signals match each other in accordance with the internal selection control signal.

PROBLEM TO BE SOLVED: To provide a register circuit decreasing a path delay between registers wherein a control signal en is propagated in comparison with that of a conventional clock gating using gated cells. SOLUTION: Since a passing permission circuit 101f receives a data signal Q and does not pass the data signal Q to a latch circuit 101g of the post stage independently of a state of a clock signal clk when the control signal en received by a register 1 changes from an active state into an inactive state and the latch circuit 101g latches the data signal Q passing through the passing permission circuit 101f independently of the state of the clock signal clk when the control signal en received by the register 1 changes from the active state into the inactive state, the register circuit carries out clock gating without using the gated cells and can decrease the path delay by delay times caused in the gated cells.

PROBLEM TO BE SOLVED: To reduce a circuit area and a test time in the case of conducting a scanning test by latching input data synchronously with a prescribed clock signal and selecting a latch operation or a through-buffer operation of a through- buffer. SOLUTION: With a control signal S set to 0, when a value of a latch enable signal G received by a NAND circuit 11 is 0, a value D1 of a data signal received by a D input 13C is outputted to a Q output 17. When the value of the latch enable signal G changes to 1, even when the value of the data signal received by a D input 13C changes to D2, an output from the Q output 17 is not immediately changed but keeps the value D1. In this case, the value D2 at the D input 13C is outputted to the Q output 17 when the latch enable signal G changes to 0. Furthermore, the control signal S is set to 1, even when the latch enable signal G is at '1', when the D input changes to a value D3, the value is outputted to the output Q.
