A semiconductor device includes a semiconductor substrate having a major surface, a source region of a second conductivity type, a drain region of the second conductivity type, and a first insulating layer formed over the major surface between the source region and the drain region. The device also includes a control electrode layer formed over the first insulating layer and a second insulating layer formed over the major surface. The device also includes a first wiring layer formed in the first contact hole and a second wiring layer formed in the second contact hole and connected to a pad and an internal circuitry, wherein the internal circuitry executes a predetermined operation and wherein the pad receives a signal from the internal circuitry or a signal from an external device.
