PURPOSE: An address comparator in a semiconductor memory device is provided to improve the degree of integration of a component by installing a redundancy latch unit outputting a comparison signal and a redundancy enable signal output unit which outputs a redundancy enable signal according to the comparison signal. CONSTITUTION: A plurality of redundancy latch units(100) latches redundancy data. The redundancy latch units output the comparison signal by comparing the latched redundancy data and the column address. A redundancy enable signal output unit(200) outputs the redundancy enable signal in response to a plurality of comparison signals outputted from the redundancy latch units. |
