Methods of operating a memory include selectively discharging a data line through a memory cell selected for sensing, discharging a sense node to the data line while a voltage level of the sense node is greater than a voltage level of the data line, and inhibiting discharging of the data line to the sense node while the voltage level of the data line is greater than the voltage level of the sense node. Sense circuits include a path between an input node and a sense node facilitating current flow from the sense node to the input node when a voltage level of the sense node is greater than a voltage level of the input node and inhibiting current flow from the input node to the sense node when the voltage level of the sense node is less than the voltage level of the input node.
