Abstract
Embodiments are described for a voltage compensated sense amplifier. One such sense amplifier includes a pair of digit line nodes respectively coupled to a pair of transistors. A first pair of switches are adapted to cross-couple the gates of the transistors to the respective digit line node and a second pair of switches are adapted to couple the gates of the transistors to a voltage supply. The first and second pair of switches are coupled to respective gates of the transistors independent of the pair of transistors being respectively coupled to the digit line nodes.
