In this paper, defect tolerance performance of switching nano-crossbar arrays is extensively studied. Three types of nanoarrays where each crosspoint behaves as a diode, FET, and four-terminal switch, are considered. For each crosspoint, both stuck-open and stuck-closed defect probabilities are independently taken into consideration. A fast heuristic(More)
