Claim Text:
1. A non-volatile data storage device comprising: a substrate; a three dimensional arrangement of non-volatile storage elements (NYSE's) positioned above the substrate, where each non-volatile storage element has respective first and second terminals provided for electrical operating of the respective non-volatile storage element; a plurality of word lines connected to the non-volatile storage elements; a plurality of pairs of adjacent but isolated-from-one-another, vertically oriented bit lines extending vertically into the three dimensional arrangement of non-volatile storage elements, the bit lines of each pair connecting to corresponding non-volatile storage elements, the adjacent but isolated-from-one-another, vertically oriented bit lines of each pair having at least one of an insulative material and an air gap interposed between them; a three dimensional arrangement of vertically oriented, bit line selector devices, each of the bit line selector devices having a respective output terminal, a respective control terminal, and a respective input terminal, the bit line selector devices being positioned below the non-volatile storage elements and above the substrate, the output terminals of the bit line selector devices being respectively coupled to respective ones of the vertically oriented bit lines; a plurality of group select lines extending between and coupling to control terminals of respective groups of the bit line select devices; and a plurality of spaced apart global bit lines positioned below the bit line selector devices and above the substrate; wherein a bit line connection point of one of the vertically oriented bit lines to a corresponding non-volatile storage element in a given layer of the three dimensional arrangement of non-volatile storage elements is not a shared connection point that is also a bit line connection point to another non-volatile storage element in the same layer of the three dimensional arrangement of non-volatile storage elements.
