Abstract:
1. 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 is provided between the first interconnect line and the second interconnect line and which includes a non-ohmic element and a memory element, the non-ohmic element including a conductive layer provided on at least one of first and second ends of the cell unit and a silicon portion provided between the first and second ends, the memory element being connected to the non-ohmic element via the conductive layer and storing data in accordance with a reversible change in a resistance state, wherein the non-ohmic element includes a P-type silicon layer and an N-type silicon layer provided in the silicon portion and an intrinsic silicon region between the P-type silicon layer and the N-type silicon layer and a first silicon germanium region provided in the N-type silicon layer, and the first silicon germanium region is formed from the N-type silicon layer to the intrinsic silicon region.
