Defect-Resilient Technique of Memristor Crossbar with Large On-Off Ratio for Implementing HTM Spatial Pooler in Near-IoT-Sensor Cognition

In this paper, we discuss memristor crossbars with large On-Off ratio are better for improving the read voltage margin, but, unfortunately, more vulnerable to memristor defects. For overcoming this problem using a defect-resilient technique, we explain and review the self-repairable boost-factor circuit presented previously. Based on the technique, we expect HTM spatial pooler with defect-resilient memristor crossbar can be suitable for realizing near-IoT-sensor cognitive hardware in future.
