ABSTRACT:
A semiconductor integrated circuit according to one aspect of the present invention may includes a plurality of driving circuits to drive a respective plurality of word lines with either a first voltage supplied from a first power supply or a second voltage supplied from a second power supply in accordance with a control signal, and a plurality of gate transistors in each of which a gate is connected to one of the plurality of word lines, and a connection state between a storage node and a bit line is changed based on the voltage provided to the word line connected to the gate. In the semiconductor integrated circuit, a gate oxide film of each of the plurality of gate transistors is thinner than a gate oxide film of each of transistors constituting the plurality of driving circuits.
