Claim 11:
12. A structure comprising:
a resistive random access memory (ReRAM) device area comprising a ReRAM device area first electrically conductive structure embedded in a fat level first interconnect dielectric material layer;
a ReRAM device area bottom electrode located on a surface of the ReRAM device area first electrically conductive structure;
a dielectric material stack located laterally adjacent to, and embedding, the ReRAM device area bottom electrode, wherein the dielectric material stack comprising a dielectric capping layer and an interlayer dielectric material;
a lower level dielectric cap located beneath the fat level first interconnect dielectric material layer;
a ReRAM device area ReRAM-containing stack located on the ReRAM device area bottom electrode, wherein the ReRAM device area ReRAM-containing stack comprises a ReRAM device area dielectric switching layer and a ReRAM device area top electrode;
a ReRAM device area dielectric encapsulation structure surrounding the ReRAM device area ReRAM-containing stack; and
a ReRAM device area contact structure located above, and in contact with, the ReRAM device area top electrode.
