Memory circuit with sense amplifier

摘要

A memory has a pre-amplifier for generating an output signal and a reference signal. The memory includes a comparator for comparing the output signal to the reference signal. The comparator includes a bias stage for generating a bias signal, wherein the bias signal is an average of the output signal and the reference signal. The comparator further includes a first output stage for generating a first comparator output signal by comparing the output signal and the bias signal. The comparator further includes a second output stage for generating a second comparator output signal by comparing the reference signal and the bias signal.
