Memristive crossbar array with applications in image processing

A memristor is a kind of nonlinear resistor with memory capacity. Its resistance changes with the amount of charge or flux passing through it. As the fourth fundamental circuit element, it has huge potential applications in many fields, and has been expected to drive a revolution in circuit theory. Through numerical simulations and circuitry modeling, the basic theory and properties of memristors are analyzed, and a memristorbased crossbar array is then proposed. The array can realize storage and output for binary, grayscale and color images. A series of computer simulations demonstrates the effectiveness of the proposed scheme. Owing to the advantage of the memristive crossbar array in parallel information processing, the proposed method is expected to be used in high-speed image processing.
