Abstract
In a decoder circuit in which a transistor for reducing power use, which is supplied at its gate with a first control signal, is connected in series with a logical gate composed of a load transistor and a plurality of transistors which are respectively supplied at their gates with address signals, there is provided an off buffer circuit which comprises a first inverter for receiving the output of the logical gate and a second inverter for receiving the output of the first inverter. To a load transistor of the second inverter is provided a second control signal delayed in phase behind the first control signal and the output of the off buffer circuit is used as a decoded output of the address signal, so that the rise and fall of a word line is reduced.
