Original Abstract Submitted

The present disclosure relates to a method for compensating non-ideality of a neuromorphic memory device. The neuromorphic memory device comprising a crossbar array of wordlines and bitlines. The crossbar array comprises a block of wordline and bitline segments, wherein memory elements of the block are programmed to represent array values. The device is configured for applying a set of inputs to the initial wordlines for performing dot products. The method comprises: performing at least one of: wordline expansion or bitline expansion of the block. The set of inputs may be applied to the initial wordlines of the expanded block and in case the bitline expansion is performed an additional input may be applied to the additional wordlines of the expanded block. The currents flowing in the bitlines of the expanded block may be measured. The dot products may be determined using the measured currents.
