Abstract:
A semiconductor integrated device, comprising:N number of circuit blocks, where N is an integer that is 2 or greater, each circuit block being connected to a respective one of a plurality of power supply terminals and a respective one of a plurality of ground terminals; a plurality of signal interface units, each signal interface unit connecting a pair of circuit blocks among the N number of circuit blocks to form a signal circuit between the respective pair of circuit blocks; a plurality of first diodes serially connected to one another in a first direction between the ground terminal of a first one of the N number of circuit blocks and the ground terminal of a K-th one of the N number of circuit blocks where K is an integer from 2 to N; and a plurality of second diodes serially connected to one another in a second direction that is opposite to the first direction between the ground terminal of the first circuit block and the ground terminal of the K-th circuit block.
