Claim Text:
1. A memory cell, comprising: a switch element; a memory element; a middle electrode formed between the memory element and the switch element; and a first outside electrode formed between the switch element and a conductive line formed below the first outside electrode; and a second outside electrode formed adjacent the memory element, wherein the first outside electrode has a first lateral dimension that is the same as a first lateral dimension of the second outside electrode and a second lateral dimension that is the same as a second lateral dimension of the second outside electrode, and wherein the first outside electrode and the second outside electrode are formed at a location other than between the memory element and the switch element, wherein a first lateral dimension of the middle electrode is different than the first lateral dimension of the first outside electrode and the second outside electrode, and wherein the first lateral dimension extends in a first direction and the second lateral dimension extends in a second direction, the first direction and the second direction being orthogonal to each other.
