ABSTRACT:
A data read circuit for use in a semiconductor memory device including an input node operatively connected to a bit line; an output node for outputting a read-out signal; a first transistor connected between the input node and the output node and turned ON and OFF in accordance with a potential of the bit line connected to a selected memory cell transistor; a second transistor connected to the output node and turned ON for a predetermined period after an address signal is changed; and a third transistor connected to the second transistor in parallel and turned ON and OFF in accordance with the read-out signal so that the third transistor is turned OFF when the selected memory cell transistor is turned ON.
