Abstract:
1. A non-volatile memory device comprising: a first electrode; a variable resistance layer formed on and above the first electrode; a second electrode formed on and above the variable resistance layer; a side wall protective insulating layer covering a side wall of the first electrode, a side wall of the variable resistance layer and a side wall of the second electrode; an interlayer insulating layer covering at least a part of the side wall protective insulating layer; an electrically-conductive layer; and a connection layer which is provided between the second electrode and the electrically-conductive layer to connect the second electrode and the electrically-conductive layer to each other, and comprises an electrically-conductive material different from a material constituting the electrically-conductive layer, wherein: the side wall protective insulating layer extends across the second electrode to a position which is above an uppermost end of the second electrode and below an uppermost end of the connection layer and an uppermost end of the side wall protective insulating layer is located above the uppermost end of the second electrode and below the uppermost end of the connection layer, when viewed from a side, the electrically-conductive layer covers an entirety of the connection layer, when viewed from a thickness direction, and the electrically-conductive layer directly contacts with at least a portion of the side wall protective insulating layer.
