A method and apparatus for characterizing and sensing the stability of a magnetic memory element. The method comprises setting a reference threshold, reading the state signal of the memory element, and comparing the magnitude of the state signal to the reference threshold, such that a state signal exceeding the reference threshold is considered stable. The apparatus comprises a reference generator having an output that is compared, in a windowed comparator, to the state signal magnitude, such that an output signal of the windowed comparator can be used to characterize the stability of the memory element.
