1. A semiconductor apparatus comprising:

  • a main circuit that includes at least one metal oxide semiconductor transistor and operates by receiving a supply of power supply voltage;

    a plurality of sensor circuits that are arranged in the main circuit and detect local characteristic variations at each position of the sensor circuits as delay information;

    an output interface circuit that collects detection results of the plurality of sensor circuits and outputs the collected results;

    an arithmetic operating section that statistically processes the detection results of the plurality of sensor circuits outputted from the output interface circuit;

    a power supply voltage controlling section that controls the power supply voltage supplied to the main circuit, based on the arithmetic operation result of the arithmetic operating section.
