Abstract
A sense amplifier test circuit that may allow for detecting soft failures may include a voltage generator circuit, a sense amplifier, and a detection circuit. The voltage generator may be operable to controllably supply different differential voltages to the sense amplifier, and the detection circuit may be operable to detect an analog voltage on the output of the sense amplifier.
