Claim 17:
18. The method of claim 16, wherein forming the memory device and the connecting structure on the memory device comprises:
providing a stack structure, the stack structure comprising a second conductive material, a third conductive material, a storage element material interposed between the second conductive material and the third conductive material, and a fourth conductive material disposing on the third conductive layer;
patterning the fourth conductive material to form the connecting structure;
patterning the third conductive material to form a top electrode;
patterning the storage element material to form a storage layer; and
patterning the second conductive material to form the bottom electrode, thereby forming the memory device having a metal-insulator-metal structure and constituted by the top electrode, the storage layer and the bottom electrode.
