Nanoelectronic devices are considered to be the computational fabrics for the emerging nanocomputing systems due to their ultra-high speed and integration density. However, the imperfect bottom-up self-assembly fabrication leads to excessive defects that have become a barrier for achieving reliable computing. In addition, transient errors continue to be a problem. The massive parallelism rendered by nanoscale integration opens up new opportunities but also poses challenges on how to manage such

By using dynamic redundancy allocation, the massive parallelism is exploited to jointly achieve fault (defect/error) tolerance and high performance. Simulation results demonstrate the effectiveness of the proposed technique under a range of fault rates and operating conditions.
