A method for forming a resistive random access memory structure. The resistive random access memory structure includes a bottom electrode; a variable resistance layer disposed on the bottom electrode; a top electrode disposed on the variable resistance layer; a protection layer surrounding the variable resistance layer, wherein a top surface of the protection layer and a top surface of the top electrode are coplanar; and an upper interconnect structure disposed on the top electrode, wherein the upper interconnect structure is electrically connected to the top electrode and directly contacts a sidewall of the protection layer.
