Abstract: In an embodiment, a sampling signal to each data signal line is generated by using an output signal outputted from each flip-flop, and a precharge signal by which the data signal line to which the sampling signal is to be outputted is precharged is generated by using an output signal outputted from an output terminal of the flip-flop.
