PROBLEM TO BE SOLVED: To reduce power consumption at standby holding operation speed by providing first and second source potential varying means. SOLUTION: In a semiconductor circuit such as a micro-processor, a memory, or the like, means such as a source potential varying means, a decoder circuit, or the like are provided to realize simultaneously low power consumption and high performance, power consumption of a semiconductor circuit can be reduced and high speed performance can be kept by selectively supplying high voltage and low voltage to a circuit being in an operation state and a circuit being in a standby state respectively.
