A clock signal control circuit that permits the on-chip circuit dimensional size to be reduced is provided. The clock signal control circuit includes a plurality of amplifier circuit elements amplifying the input clock signal and a plurality of switching elements switching the passage of the clock signal on and off, wherein the plurality of amplifier circuit elements and the plurality of switching elements are connected in such a way that the amplifier circuit elements may be connected in a series fashion when they are operational. Selecting those switching elements that are switched on causes the amplifier circuit elements to be switched so that their series-fashion connection can be reversed to allow the clock signal to travel in the backward direction.
