ABSTRACT:
A plurality of capacitive memory elements are coupled between two pairs of bit line and return line halves. A cross-coupled MOSFET sense amplifier, configured to operate in a race mode, connects between the two bit line/return line pairs. The return line of each bit line/return line pair is coupled to the bit line of the other pair so that when any selected memory element is read to generate a data signal on the bit line half associated with that memory element, the complement of that data signal is coupled to the other bit line half via the return line to increase the signal level differential across the sense amplifier.
