Claim 7:
8. A dual Resistive Random-Access Memory (RRAM) comprising:
an internal electrode;
a high k dielectric layer surrounding and in contact with the internal electrode, the high k dielectric layer having an external dielectric side not in contact with the internal electrode, the high k dielectric layer further having a first dielectric side and a second dielectric side;
a lower substrate;
an upper substrate disposed on the lower substrate;
a trench having a first trench side and a second trench side, the trench passing through the upper substrate and disposed in the lower substrate;
a first interconnect within the lower substrate, the interconnect having a first interconnect side;
a second interconnect within the lower substrate, the second interconnect having a second interconnect side, the trench being between the first interconnect side and the second interconnect side, the first interconnect side being part of the first trench side, and the second interconnect side being part of the second trench side, and the first interconnect side and the second interconnect side not being electrically connected,, wherein the internal electrode and the high k dielectric layer are disposed within the trench and the external dielectric side of the first dielectric side of the dielectric layer is electrically and physically connected to first interconnect side and the external dielectric side of the second dielectric side of the dielectric layer is electrically and physically connected to the second interconnect side.
