Abstract
A sense amplifier measures a state of a memory cell coupled to a sense node. The sense amplifier receives a control signal to enable the sense amplifier. The sense amplifier generates a voltage based on an amplifier current that is based on a sense current flowing through the sense node. The sense amplifier generates a feedback current based on the voltage to compensate variations of the sense current. The sense amplifier receives a reference control signal to enable a reference circuit to generate a reference current. The sense amplifier provides an output based on a result of comparing the sense current with the reference current, the output representing the state of the memory cell.
