Abstract:
Roughly described, a memory device has a multilevel stack of conductive layers. Vertically oriented pillars each include series-connected memory cells at cross-points between the pillars and the conductive layers. SSLs run above the conductive layers, each intersection of a pillar and an SSL defining a respective select gate of the pillar. Bit lines run above the SSLs. The pillars are arranged on a regular grid which is rotated relative to the bit lines. The grid may have a square, rectangle or diamond-shaped unit cell, and may be rotated relative to the bit lines by an angle θ where tan(θ)=±X/Y, where X and Y are co-prime integers. The SSLs may be made wide enough so as to intersect two pillars on one side of the unit cell, or all pillars of the cell, or sufficiently wide as to intersect pillars in two or more non-adjacent cells.
