Claim 0:
1. A vertical memory structure, comprising:
a stack of alternating layers of insulator material and word line material;
a series of alternating conductive pillars and insulating pillars disposed through stack, the series including at least a first conductive pillar, a first insulating pillar adjacent to the first conductive pillar and a second conductive pillar adjacent to the first insulating pillar, wherein an outside surface of the first insulating pillar is arcuate in a plane parallel to the layers of word line material;
data storage structures disposed on inside surfaces of the layers of word line material at cross-points of the first insulating pillar and the layers of word line material; and
semiconductor channel material between the first insulating pillar and the data storage structures at cross-points of the first insulating pillar with the layers of word line material, the semiconductor channel material extending around an outside surface of the first insulating pillar and directly contacting the first conductive pillar and the second conductive pillar,
wherein the series further includes:
a second insulating pillar adjacent to the second conductive pillar and a third conductive pillar adjacent to the second insulating pillar;
data storage structures disposed on inside surfaces of the layers of word line material at cross-points of the second insulating pillar and the layers of word line material; and
semiconductor channel material between the second insulating pillar and the data storage structures at cross-points of the second insulating pillar with the layers of word line material, the semiconductor channel material extending around an outside surface of the second insulating pillar to directly contact the second conductive pillar and to directly contact the third conductive pillar.
