Abstract
A flip-flop is composed of inverters including first and second MISFETs each comprising a TFT or an SOI transistor. A third MISFET, which comprises a TFT or an SOI transistor, has a gate connected to a write selecting signal line, and is connected between the output terminal of one of the inverters and a write/read signal line. A fourth MISFET has a gate connected to the gate of the other inverter. A fifth MISFET has a drain and a source connected to the write/read signal line and the drain of the fourth MISFET, and a gate connected to a read selecting signal line.
