A sense amplifier circuit includes a bitline node, a sense node, and a feedback circuit which is connected to the bitline node and to the sense node. The feedback circuit includes a cascode-connected pair of transistors configured to isolate the bitline node from an occurrence of a voltage variation on the sense node.
