PURPOSE: An address output circuit and a semiconductor memory device are provided to reduce a layout area by decreasing the number of pulse signal generating units. CONSTITUTION: A signal generating unit(1) generates a toggling signal and first and second pulse signals in response to a test signal and a burst pulse signal. An address output unit(6) receives first to fourth input addresses and outputs first to fourth output addresses in response to the toggling signal and the first and second pulse signals. A repair unit(7) repairs a word line selected by the first to fourth output addresses. [Reference numerals] (1) Signal generating unit; (6) Address output unit; (7) Repair unit |
