Patent ID: 8902634

Claim:
A resistance change type memory comprising: a resistance change element provided on a first interlayer insulating film on a substrate, wherein the resistance change element includes a lower electrode and an upper electrode, and wherein at least two resistance states of the resistance change element and data to be stored are correlated with each other; a sidewall insulating film provided on a side surface of the resistance change element; a first plug which is provided in the first interlayer insulating film, and which is connected to the lower electrode of the resistance change element; and a first interconnect which is provided on and contacts the first interlayer insulating film, and which is connected to the upper electrode of the resistance change element, wherein the resistance change element is provided immediately above the first plug, wherein the first interconnect covers the side surface of the resistance change element via the sidewall insulating film, and a portion of the first interconnect runs parallel to and faces the side surface of the resistance change element and the sidewall insulating film, and wherein an upper surface of the first plug is covered with the lower electrode and the sidewall insulating film.
