A logical value is expressed by an order that transition edges appear in a plurality of transmission signals transmitting respectively on a plurality of signal lines. Otherwise, the logical value is expressed by a time difference between the transition edge of the transmission signal transmitting on the signal line and a transition edge of a standard timing signal. Therefore, a large amount of data can be transmitted through one signal line. Since a large amount of data can be transmitted by one transmission, it is possible to substantially increase the data transfer rate. Since only a small number of the signal lines are necessary, it is possible to reduce the number of input circuits and output circuits of the transmission signals, to reduce power consumption, and to reduce the wiring area of the signal lines.
