Abstract
A data receiving circuit that can accurately obtain a data signal corresponding to information data from a high speed high density transmitted signal, and a semiconductor device including the data receiving circuit. The amplitude of a first differential signal corresponding to a level difference between a pair of received differential signals, generated in a first differential stage, is amplified and binalized to obtain a received data signal. A second differential signal corresponding to the level difference between the received differential signals, and a third differential signal which is a phase-inverted signal of the second differential signal are generated in a second differential stage provided separately, and a current corresponding to the second differential signal and a current corresponding to the third differential signal are discharged into the respective ones of the pair of transmission lines, thereby suppressing the amplitudes of the received differential signals.
