1. A sense amplifier comprising:
a first inverter responsive to a first output of a latch, wherein a source terminal of a first transistor of the first inverter is configured to receive a sense enable signal, and wherein a source terminal of a second transistor of the first inverter is connected to ground; a second inverter responsive to a second output of the latch, wherein a source terminal of a first transistor of the second inverter is configured to receive the sense enable signal, and wherein a source terminal of a second transistor of the second inverter is connected to ground; and a first isolation device responsive to the sense enable signal, wherein a drain terminal of the first isolation device is connected to the first output of the latch, wherein the first isolation device is connected to a first bit line and wherein the first isolation device is configured to isolate the first inverter from the first bit line when the source terminal of the first transistor of the first inverter receives the sense enable signal.
