ABSTRACT:
A memory sense amplifier includes a sample and hold circuit followed by a differential amplifier. The sample and hold circuit samples a reference voltage on a bit line of a memory circuit when the sense amplifier is reset and a signal voltage on the same bit line when a signal representing a data bit is present in the bit line. The differential amplifier amplifies the difference between the signal voltage and the reference voltage.
