ABSTRACT:
A semiconductor circuit apparatus comprises a substrate and a circuit block including a memory formed on the substrate. The circuit block performs regular operations at a first power supply voltage in an active mode, and a part of the circuit block is stopped and the memory keeps stored data at a second power supply voltage smaller than the first power supply voltage in a power save mode. The memory holds the stored data during the power save mode, resulting in higher speed return to a regular active mode, as well as power consumption reduction.
