    Abstract: 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.

    Abstract: A method of fabricating an integrated circuit device includes forming first and second mask structures on respective first and second regions of a feature layer. Each of the first and second mask structures includes a dual mask pattern and an etch mask pattern thereon having an etch selectivity relative to the dual mask pattern. The etch mask patterns of the first and second mask structures are etched to partially remove the etch mask pattern from the second mask structure. Spacers are formed on opposing sidewalls of the first and second mask structures. The first mask structure is selectively removed from between the spacers in the first region to define a first mask pattern including the opposing sidewall spacers with a void therebetween in the first region, and a second mask pattern including the opposing sidewall spacers with the second mask structure therebetween in the second region.
