PROBLEM TO BE SOLVED: To reduce defective operation due to a history effect in a circuit that uses a MOS type transistor having a floating body, provide a device with good electrical properties, and improve sensitivities of a sense amplifier circuit, a latch circuit that contain the MOS type transistor as components. SOLUTION: As shown in Figure 1, electrical properties of the MOS type transistor 4901a, 4901b are utilized during first duration (effective duration) 5001 to output a signal required for circuits other than a first circuit. During second duration (pausing duration) 5002 excluding the first duration 5001, step waveform voltages 5003a, 5003b greater than or equal to a threshold of the MOS type transistor are supplied between gate sources for the MOS type transistors 4901a, 4901b.
