Bit line pre-charge circuit and method

Abstract:

A bit line is pre-charged based on a clock signal internal to a bit line pre-charge circuit when a bit line pre-charge window is within a margin of a predetermined pre-charge window. A bit line is pre-charged based on a clock signal external to the bit line pre-charge circuit when the bit line pre-charge window is outside the margin of the predetermined pre-charge window.
