ABSTRACT:
In a semiconductor integrated circuit, power lines or ground lines of a plurality of circuit blocks having equivalent functions are coupled via a switch circuit to a common main power line or main ground line on a semiconductor integrated circuit chip or semiconductor wafer. The main power line is supplied with power source potential and said main ground line with ground potential. A switch control circuit selectively switches the switch circuit ON or OFF so that defective circuit blocks may be deactivated.
