Abstract
An address input buffer of a semiconductor memory device comprises an address input terminal, a column address switch, a row address switch, a column address latch connected to the column address switch, a row address latch connected to the row address switch, and an input buffer connected to the address input terminal, and the common node of the column address switch and the row address switch and controlled by an input buffer control signal. Thus, layout area can be reduced by buffering the row and column address input signals with one input buffer without separating the column and row address buffers.
