ABSTRACT:
A semiconductor device includes at least a plurality of first interface circuits electrically coupled between first and second power supply lines belonging to a first power supply system, one or more first circuits including a first surge current path coupled to the first power supply line and a second surge current path coupled to the second power supply line, a plurality of second interface circuits electrically coupled between third and fourth power supply lines belonging to a second power supply system independent from the first power supply system, and further electrically coupled to a corresponding interface circuit of the plurality of first interface circuits, respectively, and one or more second circuits including a third surge current path coupled to the first circuit and have a first time constant derived by a first resistance coupled to the third surge current path and a first capacitance.
