Abstract
A non-volatile memory device comprising a memory cell region having a plurality of co-planar memory cell planes arranged in a plane parallel to a semiconductor substrate, with each memory cell plane comprising a plurality of sub-planes disposed adjacent one another along an axis that is parallel to the substrate. Further, each memory cell plane comprises a plurality of sense amplifier regions arranged along the axis in an alternating pattern with the sub-planes such that adjacent to each sub-plane is a sense amplifier region and each sense amplifier region is operable with respect to at least a fraction of the bit lines of the two sub-planes immediately adjacent the sense amplifier region.
