Abstract

A system for pre-charging and equalizing potentials on a bitline pair in a DRAM integrated circuit. The system includes an equalization circuit at one position on the bitline pair and another equalization circuit at another position on the bitline pair. As charge is distributed between the bitlines and to/from the pre-charge potential source through multiple conduction paths, the pre-charge and equalization time of the bitlines is reduced.
