ABSTRACT:
A sense amplifier apparatus for use in a memory array having a plurality of memory cells is provided. The sense amplifier apparatus includes a differential sense amplifier and a dynamic sense amplifier. The differential sense amplifier has a first set of switches for driving the voltages of the sense amplifier apparatus and are coupled to a complementary pair of outputs. Also provided are a second set of switches, which are coupled to a complementary pair of input lines so as to amplify the input signal on either of the pair of input lines to a first signal level at a first rate of amplification. The dynamic sense amplifier shares the first set of switches with the differential sense amplifier and further includes a third set of switches that are coupled to a complementary pair of input lines and the output lines and also a sense enable line. This allows the first signal level to be amplified to a second signal level at a second rate of amplification faster than the first rate of amplification.
