Patent ID: 8537592

Claim:
An array of nonvolatile memory cells, comprising: a plurality of vertically stacked tiers of nonvolatile memory cells, individual of the tiers comprising: a first plurality of horizontally oriented first electrode lines; a second plurality of horizontally oriented second electrode lines crossing relative to the first electrode lines; and individual of the memory cells comprising: a crossing one of the first electrode lines and one of the second electrode lines; programmable material, a select device in series with the programmable material, and current conductive material in series between and with the programmable material and the select device; the programmable material and the select device being in series with such crossing ones of the first and second electrode lines; and the programmable material and the select device are oriented for predominant current flow into or out of the crossing one first electrode line out of or into, respectively, one of the programmable material or select device in a horizontal direction, and for predominant current flow into or out of the crossing one second electrode line out of or into, respectively, the other of the programmable material and select device in a vertical direction.
