摘要:
Apparatus and methods for cross-coupling bitline segments in a memory array are provided. Bitline segments, each having a plurality of drive circuits and output circuits connected thereto, are cross-coupled such that the states of a first bitline segment can be transmitted to another bitline segment. The segments are conductively isolated such that their resistance-capacitance characteristics can be controlled while providing bi-directional data transfer along the entire length of the segmented bitline. Embodiments are also disclosed that support cross-coupling of bitline segments which are operated using pre-charge/discharge techniques.
