A transfer circuit for signal lines comprises a bipolar transistor and two MIS transistors. A base of the bipolar transistor is connected to a first line of the signal lines, a collector of the bipolar transistor is connected to a power source, the two MIS transistors are connected in series, the connected point is connected to an emitter of the bipolar transistor, and one end of the series-connected MIS transistors is connected to the first line and the other end is connected to a second line of the signal lines. When the first line is transferred to the second line, the MIS transistor connected between the base and emitter of the bipolar transistor is made non-conductive and the other MIS transistor connected to the second line is made conductive. The transfer circuit constituted as above can carry out the transfer of the signal lines at a high speed by rapidly charging the second line.
