SEMICONDUCTOR INTERGRATED CIRCUIT AND METHOD OF SUPPLYING POWER TO THE SAME

摘要

PURPOSE: A semiconductor integrated circuit and a power supply method thereof are provided to reduce power consumption by combining circuit blocks between a power voltage and the ground in a cascade form. CONSTITUTION: A power voltage generator(110) generates first and second power voltages. The power voltage generator provides the first power voltage to a first power bus. The power voltage generator provides the second power voltage to a power bus. One or more first circuit blocks(120) are combined between the first power bus and the second power bus. One or more second circuits(130,140,150) are combined with the power bus and the ground.
