A sense amplifier has a charge sharing compensator to eliminate wake-up delays in an output signal. The charge sharing compensator comprises a capacitor or a charge storing means to compensate for charges in a charge sharing path that has two different voltage potentials. The compensator also has a transistor for selecting a signal path to transfer charges from the capacitor, eliminating charge sharing in the bit line path of the sense amplifier. Another aspect of the present invention is a method for resolving charge sharing problems that comprises steps of choosing a proper value for a compensating capacitor, choosing a control signal for a charge sharing compensation means, and clamping down an input terminal of the sense amplifier.
