Abstract:
Bit line equalization driver circuits and related apparatuses, methods, and computing systems are disclosed. An apparatus includes an output inverter including a pull-up transistor and a pull-down transistor electrically connected in series between a pull-up node and a pull-down node. An output node is electrically connected between the pull-up transistor and the pull-down transistor. The pull-down transistor includes a short length transistor having a degradation voltage potential across the pull-down transistor below which the pull-down transistor is configured to operate to avoid degradation of the pull-down transistor. The apparatus also includes biasing circuitry configured to control voltage potentials at the pull-up node and the pull-down node to enable the output inverter to assert, at the output node, an output voltage potential that is greater than the degradation voltage potential higher than a low power supply voltage potential at the low power supply node.
