Abstract:
1. A semiconductor circuit device having active and standby states, comprising: a main power supply line; a sub power supply line; a first switching element, connected between said main power supply line and said sub power supply line, turned on when a power supply is initially turned on, turned on in said active state, and turned off in said standby state; a main ground line; a sub ground line; a second switching element, connected between said main ground line and said sub ground line, turned on when a power supply is initially turned on, turned on in said active state, and turned off in said standby state; a plurality of first logic circuits each having a power supply node connected to said main power supply line and a ground node connected to said sub ground line for outputting a logic high level signal in said standby state; and a plurality of second logic circuits each having a power supply node connected to said sub power supply line and a ground node connected to said main ground line for outputting a logic low level signal in said standby state.
