Patent ID: 8546779

Claim:
A resistance change memory comprising: a first interconnect line extending in a first direction; a second interconnect line extending in a second direction intersecting with the first direction; and a cell unit which includes a non-ohmic element having a first silicide layer on a first end of the non-ohmic element, and a memory element to store data in accordance with a reversible change in a resistance state, the cell unit being provided at an intersection of the first interconnect line and the second interconnect line, and the first end having the first silicide layer being at a position on an opposite side of the non-ohmic element than the memory element, wherein the first silicide layer includes a 3d transition metal element and an additional element which combine with an Si element to form the first silicide layer, the 3d transition metal element has a first atomic radius, and the additional element has a second atomic radius greater than the first atomic radius.
