Abstract
A semiconductor integrated circuit is provided having first and second logic circuits coupled to first and second sub-power supply lines, respectively. First and second switching transistors are also provided to connect the first and second sub-power supply lines to a main power supply line. The first and second switching transistors are kept off in an operation stop state of the first and second logic circuits, and are kept on in operable state of the first and second logic circuits.
