Abstract
It is an object to provide a highly reliable semiconductor device which operates normally even when a communication distance is extremely short. A semiconductor device which transmits/receives data by wireless communication includes a comparison circuit which compares electric power supplied form outside with electric power serving as a reference; a bias circuit portion which outputs a protection signal and a modulation signal in accordance with output of the comparison circuit; and a protection/modulation circuit which performs protection to prevent degradation and breakdown of elements of the semiconductor device and modulation to transmit data, with one circuit.
