A semiconductor device comprises transmission lines, inverting circuits, first, second and third switches, global sense amplifiers, and a control circuit. The first switch switches between the transmission line and the input of the inverting circuit, the second switch switches between the transmission line and the output of the transmission line, and the third switch switches between the adjacent transmission lines. The control circuit turns off the first and second switches so that the transmission lines are brought into a floating state in a state where signals of the transmission lines are held in the inverting circuits by the global sense amplifiers. After charge sharing of the transmission lines occurs by turning on the third switches within a predetermined period, the control circuit turns off the second switches so that the transmission lines are inverted and driven via the inverting circuits and the second switches.
