The 4th fundamental circuit element-memristor has received significant attention since a real device was recently demonstrated for the first time.The study on memristors will bring about a revolution in circuit theory and even a change in our lifestyle.The hybrid of the CNN（cellular neural network） scheme and the memristor will greatly expand the applications of the memristor.In this paper,we consider using memristors to implement the neighborhood connections of a CNN base on the memory characteristics of memristors and cellular neural network,which is parallel and highly efficient in data processing.This proposed scheme is a special cellular neural network with the property of the memristor.A series of computer simulations have verified the effectiveness of the proposed scheme in noise removal and edge extraction.
