Claim 18:
19. The method of claim 16, wherein forming the memory device and the connecting structure on the memory device comprises:
forming a lower electrode;
disposing a second insulating layer on the lower electrode, the second insulating layer comprising a second recess exposing the lower electrode;
providing a stack structure on the second insulating layer, the stack structure further extending into the second recess and comprising a storage element material and a second conductive material located on the storage element material;
patterning the second conductive material to form the connecting structure; and
patterning the storage element material to form a storage layer, thereby forming the memory device having a metal-insulator-metal structure and constituted by the lower electrode, the storage layer and the connecting structure.
