Abstract

Analog conductance of resistive memories is attractive for implementing the weights in neuro-inspired algorithms. One of the most popular deep learning algorithms is the convolutional neural network (CNN). In this paper, we review our recent progress on using resistive memories for neuro-inspired computing. First, we optimized the iterative programming protocol to tune the weights of HfOx based resistive memories by adjusting the pulse amplitude incremental steps, the pulse width incremental steps, and the start voltages. Then, we demonstrated the key operation in the CNN-the convolution kernel on a 12×12 cross-point array. As a proof-of-concept demonstration, we use the offline trained edge filters to detect both horizontal and vertical edges of the 50×50 pixels of a grayscale dog image. The experimental kernel operation matches the simulation results.
