Abstract:
A semiconductor device, comprising:a first main power supply line transmitting a voltage of a first logic;a first subpower supply line;a logic gate including a first insulated gate type field effect transistor having an SOI structure in which a semiconductor layer as an element forming region is formed on an insulating layer and having a gate receiving an input signal, one conduction node connected to said first subpower supply line, another conduction node connected to an internal output node and a body region connected to said first main power supply line and having a channel formed thereon when conductive; anda first switching transistor provided to respond to an operation cycle defining signal defining an operation cycle of said logic gate having an active cycle and a stand-by cycle, and rendered conductive when said operation cycle defining signal defines said active cycle, for electrically connecting said first main power supply line and said first subpower supply line.
