Patent ID: 7800970

Claim:
A sense amplifier circuit, comprising: a current sense amplifier configured to amplify differential input currents to generate differential output voltages and configured to provide the differential output voltages to a sense amplifier output line pair; a voltage sense amplifier coupled to the sense amplifier output line pair, the voltage sense amplifier configured to amplify the differential output voltages on the sense amplifier output line pair and configured to be activated at a time later than a time of activation of the current sense amplifier; an output stabilizing circuit coupled to the sense amplifier output line pair, the output stabilizing circuit configured to stabilize the differential output voltages on the sense amplifier output line pair, the output stabilizing circuit having a positive input resistance; a precharger/equalizer circuit configured to precharge the sense amplifier output line pair to a first precharge voltage and configured to equalize the sense amplifier output linepair, in response to a first control signal; and an equalizer configured to equalize the sense amplifier output line pair in response to a second control signal that is activated at a time later than a time of activation of the first control signal.
