Abstract
Plural transmitter units generate plural currents corresponding to plural logical values, respectively, and propagate the currents to a common signal line. The common signal line synthesizes the currents generated by the transmitter units, and propagates them to a receiver unit as a synthetic current. The receiver unit restores the logical values the transmitter units generated, in accordance with the synthetic current. The values of the currents the transmitter units generate in correspondence with the logical values each differ, so that the value of the synthetic current can be changed for every combination of logical values. Accordingly, the receiver unit can restore the logical values outputted from the respective transmitter units, based on the synthetic current. That is, employing the common signal line enables signals transmitted from the transmitter units to be simultaneously received. Consequently, the number of signal lines laid between the transmitter units and the receiver unit is reduced.
