A row address circuit of a semiconductor memory device includes a signal generator that generates a pulse in an enable signal for an output circuit that provides a decoded address. The pulse has a first edge that is delayed relative to a corresponding first edge of a refresh count signal and a second edge that precedes a corresponding second edge of the count signal. Accordingly, the enable signal prevents changes in the output signal that could otherwise result from input of an external address during a refresh operation. Therefore, the present invention can prevent an invalid address by cutting off a predecoder before a transition of a refresh count signal to prohibit a change of a predecoded output.
