ABSTRACT:
Methods for controlling the timing of a pre-charge operation in a memory device are provided. In embodiments of the present invention, the timing may be controlled by dynamically selecting a word line off time based on information about a number of column cycles. This may be accomplished, for example, by routing a word line disable signal via one of a first plurality of delay paths. The methods may further include dynamically selecting a bit line equalization start time based on the information about the number of column cycles. This may be accomplished, for example, by routing a bit line equalization start signal via one of a second plurality of delay paths. Pursuant to still further embodiments of the present invention, systems for controlling timing in a memory device are provided which include a control circuit that is configured to select a word line off time from a plurality of word line off times in response to a word line signal and information about a number of column cycles.
