    • Sensing circuits for determining the state of memory cells include a sense amplifier. The sense amplifier includes an imbalanced cross-coupled latch (ICL), a first gate field effect transistor (FET) between a bit line (BL) and a first output node, and a second gate FET between a bit line inverse (BLB) and a second output node. The ICL includes a first pull down FET between the first output node and an enable FET connected to electrical ground, and a second pull down FET between the second output node and the enable FET. Channel widths of the second pull down FET and the second gate FET are greater than channel widths of the first pull down FET and the first gate FET to enhance the ability to detect a one (1) and a zero (0) stored in a memory cell connected to the sense amplifier.

    • Methods for determining the state of memory cells include using an asymmetric sense amplifier. The methods include sensing the voltages on bit line (BL) and bit line bar (BLB) signals by coupling the BL to a first output node of an imbalanced cross-coupled latch (ICL), the ICL outputting a logic low value if the a difference between the a voltage on the BL and a voltage on the BLB exceeds a threshold. Sensing the voltages includes providing at least a first and a second pull down field effect transistor (FET) each having a channel coupled between the first and second output nodes and a ground node, respectively, in a cross coupled arrangement, wherein the second pull down FET has a channel width that is greater than a channel width of the first pull down FET. Additional methods are disclosed.
