ABSTRACT:
A bus circuit of this invention has a bus line. A bus input circuit and a bus output circuit are connected to the bus line. The bus line is charged by a precharge circuit. The bus output circuit outputs an output signal to the bus line by discharging or not discharging potential of the bus line. The bus input circuit inputs a signal from the bus line. The bus input circuit includes a feedback circuit which inputs potential of the bus line as the signal, amplifies the signal in accordance with a change of the signal, and feeds back the amplified result to the bus line.
