Apparatus and methods for providing a high density memory array with reduced read access time are disclosed. Multiple split bit lines are arranged along columns of adjacent memory bit cells. A multiple input sense amplifier is coupled to the multiple split bit lines. The loading on the multiple split bit line is reduced, and the corresponding read speed of the memory array is enhanced over the prior art. The sense amplifier and the memory bit cells have a common cell pitch layout height so that no silicon area penalty arises due to the use of the multiple split bit lines and sense amplifiers. Increased memory array efficiency is achieved.
