ABSTRACT:
A shift register circuit includes a first two-input NOR circuit to which a first data signal and a selection signal are input, a second two-input NOR circuit to which a first reverse data signal having an opposite phase from the first data signal and the selection signal are input, a third two-input NOR circuit to which a second data signal and a reverse selection signal having an opposite phase from the selection signal are input, a fourth two-input NOR circuit to which a second reverse data signal having an opposite phase from the second data signal and the reverse selection signal are input, a first three-input NOR circuit to which output signals from the first and third two-input NOR circuits and the clock signal are input, and a second three-input NOR circuit to which output signals from the second and fourth two-input NOR circuits and the clock signal are input. Since the three-input NOR circuits are employed, the number of NOR circuits through which the input data signal travels is decreased, resulting in an increase in the operation speed of the shift register circuit.
