Abstract
A semiconductor integrated device is provided which consists of a plurality of circuit blocks. Each circuit block is connected to a power supply terminal and a ground terminal. Signal interface sections connect signal circuits among the circuit blocks. A plurality of first diodes are serially connected to one another in a first direction between the ground terminal of a first one of the circuit blocks and the ground terminal of another of the circuit blocks. A plurality of second diodes are 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 another circuit block.
