An address selection device comprising an address buffer for receiving an address selection signal to produce an output signal which is complementary to the address selection signal; and a decoder circuit for decoding the address selection signal which includes a plurality of MOS transistors connected in parallel with one another and for receiving at their gates corresponding address bit signals of the address selection signal, a MOS transistor as a load resistor connected in series with said plurality of MOS transistors, and a MOS transistor connected between the load resistor MOS transistor and a power source terminal for operating a power source switch and for receiving at the gate a specified bit signal of the complementary signal applied from the address buffer.
