Claim 9:
10. A semiconductor device, comprising:
a first transistor, comprising:
a first conductive feature; and
a second conductive feature disposed on the first conductive feature;

a first resistive random access memory (RRAM) resistor;
a second RRAM resistor, wherein the first RRAM resistor comprises a first resistive material layer, a first electrode shared by the second RRAM resistor, and a second electrode; the second RRAM resistor comprises the first electrode, a second resistive material layer, and a third electrode; the first electrode is electrically coupled to the first transistor, and wherein the first electrode protrudes from the second conductive feature of the first transistor; and
a circuit, comprising:
a second transistor;
a third RRAM resistor; and
a fourth RRAM resistor, wherein the circuit is electrically coupled to the second conductive feature of the first transistor, wherein the third RRAM resistor comprises a fourth electrode shared by the fourth RRAM resistor, a third resistive material layer, and a fifth electrode, the fourth RRAM resistor comprises the fourth electrode, a fourth resistive material layer, and a sixth electrode, and the fourth electrode is electrically coupled to the first electrode, and
wherein the first electrode and the second electrode are spaced apart by a first distance, the first electrode and the third electrode are spaced apart by a second distance greater than the first distance, the fourth electrode and the fifth electrode are spaced apart by a third distance, the fourth electrode and the sixth electrode are spaced apart by a fourth distance greater than the third distance, and a sum of the first distance and the fourth distance is substantially equal to that of the second distance and the third distance.
