ABSTRACT:
A sense amplifier is coupled to a pair of bit lines for detecting and amplifying a voltage differential therebetween. The sense amplifier has a first differential amplifier coupled to the pair of bit lines enabled in response to a first signal. The sense amplifier also has a second differential amplifier coupled to the pair of bit lines which is enabled a predetermined time duration following the occurrence of the first signal.
