摘要:
Memories, pre-charge circuits, and methods for pre-charging memory are described. One such method includes providing a voltage to a data line and adjusting the voltage provided to the data line based at least in part on a voltage difference between a target voltage and a voltage of the data line being pre-charged. An example pre-charge circuit includes a voltage generator configured to generate an output voltage having a magnitude based at least in part on a reference voltage and a feedback signal, first and second drivers, and a voltage detector. The voltage detector is configured to determine a voltage difference between the reference voltage and a sample voltage of a data line coupled to the second driver and generate the feedback signal based at least in part on the difference.
