Patent ID: 8120068

Claim:
A non-volatile memory, comprising: a first set of array lines elongated in a first direction; a second set of array lines elongated in a second direction substantially orthogonal to the first direction, the second set of array lines being vertically separated from the first set of array lines; and a set of pillars in communication with the first set of array lines and the second set of array lines, each pillar of the set of pillars including a first end surface and a second end surface, the first end surface connecting to one array line of the first set of array lines, the second end surface having a first portion connecting to one array line of the second set of array lines and a second portion connecting to a different array line of the second set of array lines, said each pillar including a first non-volatile storage element having a state change element and a steering element and a second non-volatile storage element having a state change element and a steering element, the first portion of the second end surface of said each pillar having a dimension in the first direction that is less than a dimension of the array lines of the second set in the first direction, the second portion of the second end surface of said each pillar having a dimension in the first direction that is less than the dimension of the array lines of the second set in the first direction.
