A mode setting circuit comprises a gate part which contains a PMOS transistor(64) and a NMOS transistor(66), a NMOS transistor(74) to be connected with an inverter's(76) output terminal, inverter chains(70,72) and an inverter(68) which generates a mode setting signal. This kind of mode setting circuit receives the input of the signal set at a node(N4) in the low address buffer and when the mode setting signal becomes enabled, it controls the gate part. Thus, by the combination of the signals which is independent from the control signal, the mode setting circuit can be generated.
