Abstract
A sense margin is improved for a read path in a memory array. Embodiments improve the sense margin by using gates with a lower threshold voltage in a read column multiplexer. A cross coupled keeper can further improve the sense margin by increasing a voltage level on a bit line storing a high value, thereby counteracting leakage on the 'high' bit line.
