Abstract
A balanced differential amplifier sense amplifier senses the voltage level in a selected single bit line memory cell. The output of the selected single bit-line memory cell is connected to one input of the balanced differential sense amplifier while the other input receives a reference voltage provided by a corresponding single bit-line memory cell from a complementary memory bank. A supporting voltage is added-to/subtracted-from the reference voltage by providing a 'bump' or 'dip' mechanism or by utilizing a charge-sharing structure, in order to compensate for the variation in the sensed bit-line voltage over the duration of the sensing interval as well as for the disparity in voltage level from cell to cell.
