Digital Offset for RRAM-based Neuromorphic Computing: A Novel Solution to Conquer Cycle-to-cycle Variation

Resistance variation in memristor device hinders the practical use of resistive random access memory (RRAM) crossbars as neural network (NN) accelerators. Previous fault-tolerant methods cannot effectively handle cycle-to-cycle variation (CCV). Many of them also use a pair of positive-weight and …
