PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device capable of improving power efficiency. SOLUTION: The semiconductor integrated circuit device includes two synchronous operation circuits 11 and 12, a plurality of delay lines 13a, 13b, ..., 13n, a delay detection unit 14, and a control unit 15. The two synchronous operation circuits operate by synchronizing with a clock signal CLK. The plurality of delay lines 13a, 13b, ..., 13n are connected between the two synchronous operation circuits in a parallel configuration to enable signal transmission. The delay detection unit detects each delay time in the plurality of delay lines 13a, 13b, ..., 13n. The control unit controls to select one delay line among the plurality of delay lines based on the detection result by the delay detection unit 14, and prevent signal transmissions other than the one delay line selected.
