A sense amplifier (SA) and a method for operating the SA are provided. The SA includes a first differential pair of transistors configured to receive a first differential input, a second differential pair of transistors configured to receive a second differential input, and a current source configured to source a current to flow through the first and second differential pairs of transistors. The method includes receiving by a first differential pair of transistors a first differential input, receiving by a second differential pair of transistors a second differential input, and flowing a current through the first and second differential pairs of transistors. A multi-bank memory is provided. The memory includes a first bank of memory cells and a second bank of memory cells sharing the disclosed SA.
