| 摘要 |
The invention intends to provide a semiconductor integrated circuit including MOS transistors, which is able to operate at a high-speed with a low power supply voltage in the active mode, and to reduce the power consumption resulting from the leakage current in the standby mode. In view of the foregoing object, the semiconductor integrated circuit of the invention is comprised of a first power supply line to which a first power supply potential is supplied, a virtual power supply line, a logic circuit connected to the virtual power supply line, a power control transistor provided between the first power supply line and the virtual power supply line, having a control electrode to which a first control signal is inputted, a second power supply line to which a second power supply potential is supplied, and a substrate potential control circuit connected to a substrate on which the power control transistor is formed, the first power supply line, and the second power supply line.
