摘要

PROBLEM TO BE SOLVED: To reduce the occupied area of power supply constitution in a semiconductor integrated circuit including transistors(TRs) operated with low voltage and having low thresholds. ;SOLUTION: The semiconductor integrated circuit is provided with a power supply circuit consisting of a global power supply line VCC, a local power supply line QVCC and a global ground line VSS, a low threshold logical circuit 101 connected between the power supply line QVCC and the ground line VSS and an information storing circuit 103 connected between the power supply line VCC and the ground line VSS. The circuit 103 is provided with a low threshold transfer gate 114, a low threshold inverter 117 for receiving a signal from the gate 114 and high threshold inverters 116, 118 for connecting between the input and output of the inverter 117. Mode switch TRs 105, 119, 120 to be turned off in a stand-by mode are respectively connected between the output stage of the low threshold logical circuit 101 and the ground line VSS, between the inverter 117 and the power supply line VCC and between the inverter 117 and the ground line VSS.;COPYRIGHT: (C)1999,JPO
