ABSTRACT:
Disclosed herein is a semiconductor circuit includes a p-channel MOS transistor 110 whose source and drain path is connected between a word line 111 and a terminal 105 supplying a charging voltage higher than the power supply voltage and its back gate connected to a terminal 104 for supplying a back gate bias voltage VPB, in which the back gate bias voltage is applied to the back gate of the p-channel MOS transistor 110 so as to energize the p-channel MOS transistor 110 to supply the charging voltage VPM to the word line 111 when the word line 111 is selected, and to deenergize the p-channel MOS transistor 110 to supply the power supply voltage to the word line 111 when the word line 111 is not selected.
