A semiconductor memory device includes at least one cell array and first and second bit line sense amplifying units. A cell array includes a plurality of bit line pairs and a plurality of bit line equalizers connected to each other through a signal line. Each bit line equalizer equalizes a corresponding bit line pair. The first and the second bit line sense amplifying units are alternately connected to the bit line pairs and receive respective bit line equalization signals.
