ABSTRACT:
Systems and methods for increasing the amount of current that can flow through the data line pull-down transistors in a sense amplifier by tying the bodies of these transistors to a voltage other than ground. In one embodiment, the bodies of the data line pull-down transistors in a sense amplifier are tied to the intermediate nodes on the opposing side of the sense amplifier to increase the current flow through the data line pull-down transistors, and also to reduce the voltage at the intermediate node that will be pulled low by the action of the bit line transistors. In one embodiment, the sense amplifier also includes pre-charge circuits which pre-charge the intermediate nodes to a predetermined voltage that is not reduced by the threshold voltage of the pull-down transistors.
