ABSTRACT:
A dynamic random access memory device is equipped with sense amplifier circuits for developing differential voltage levels on associated bit line pairs, and the sense amplifier circuits are coupled through a discharging path with a ground voltage line, wherein the discharging path is implemented by a plurality of discharging sub-paths sequentially grounded by a control circuit so that the differential voltage levels are rapidly developed by smooth voltage decay on the associated discharging sub-paths, thereby improving the data access time.
