ABSTRACT:
A semiconductor integrated circuit, a semiconductor integrated circuit control method, and a signal transmission circuit realizing optimization of the performance of a semiconductor integrated circuit and reduction of the power consumption. In the semiconductor integrated circuit, the semiconductor integrated circuit control method, and the signal transmission circuit, functional circuit blocks are composed of MIS transistors fabricated on an SOI structure silicon substrate and have at least one potential set including a high-potential side potential, a low-potential side potential, a substrate potential of a P-channel MIS transistor, and a substrate potential of an N-channel MIS transistor. Power supply wirings supply voltages to the potentials included in the potential set, a controller determines the values of the voltages induced in the power supply wirings and instructs a power supply control IC to generate the voltages of the determined values, and the power supply control IC generates the voltages induced in the power supply wirings according to the instruction of the controller.
