SEMICONDUCTOR DEVICE AND SIMULTANEOUS BIDIRECTIONAL SIGNAL TRANSMISSION SYSTEM COMPRISING THE SAME

摘要

PURPOSE: A semiconductor device and a simultaneous bidirectional signal transmission system comprising the same are provided to transmit and receive a 4-level signal bidirectionally at the same time without regard to impedance mismatch, signal interference, serial communication distance and data skew. CONSTITUTION: A simultaneous bidirectional signal transmission system(100) comprises the first semiconductor device(110), the second semiconductor device(140) and a transmission line(130) connected between the first and the second semiconductor device. The first semiconductor device comprises the first output MUX(111) converts the first binary data into the first signal having one level among at least four levels, and the first transmitter(113) being connected to the first output MUX and outputting the first signal to the second semiconductor device through the transmission line. The second semiconductor device comprises the second output MUX(141) converting the second binary data into the second signal having one level among at least four levels, and the second transmitter(143) being connected to the second output MUX and outputting the second signal to the first semiconductor device through the transmission line.
