ABSTRACT:
A semiconductor integrated device including a first circuit block, a second circuit block, a first supply interconnection connected to the first circuit block to supply power thereto, a second supply interconnection connecting the first supply interconnection to the second circuit block, and a switch inserted across the first and second supply interconnections. The switch has a structure equivalent to a plurality of switching elements disposed in parallel on a substrate. The switch is opened by a break command output from the first circuit block so that the second supply interconnection is disconnected from the first supply interconnection, thereby preventing a standby current from flowing to the second circuit block when it is unused. This can solve a problem of a conventional semiconductor integrated device in that the standby current flowing to the second circuit block wastes power even if the second block is not used.
