Abstract
A bit-line equalizer, a semiconductor memory device including the bit-line equalizer, and a method for manufacturing the bit-line equalizer, in which the bit-line equalizer includes: first and second polysilicon gates formed in a first direction in proximity to each other, the first and second polysilicon gates having a predetermined distance between them; and a plurality of equalizing transistors formed in a second direction along the first and second polysilicon gates, the equalizing transistors equalizing bit-line pairs, with the equalizing transistors being alternately formed in proximity to the first and second polysilicon gates. The bit-line equalizer can vary the widths of the equalizing transistors irrespective of a memory cell pitch in order to improve an equalizing time.
