The Resistive Random Access Memory (RRAM) is a new type of non-volatile memory based on the resistive device. Researchers are currently moving from device development to circuit design and implementation, hoping fabricate chips that can be deployed in market near future. However, so far low manufacturing yield still major issue. In this paper, we propose defect fault models specific RRAM, i.e., Over-Forming (OF) Read-One-Disturb (R1D) fault.
