Abstract
A memory circuit includes a sense amplifier in which a single reference signal is compared to two data signals from two memory cells. The reference signal is generated from the combination of memory cells in opposite logic states. The data signal capacitance is matched to the reference signal capacitance. With reduced but matched capacitance both high speed and high sensitivity can be achieved.
