Abstract

Reduction of power consumption of integrated circuits due to reduced leakage is provided by driving an integrated circuit with a first drive potential (Vdd) and a second drive potential (Vsscore), switching the second drive potential to a ground potential in active mode using a power switch (30), and connecting a substrate potential of the integrated circuit to the ground potential.
