| Video Discription | On November 13, 2017, Professor Wei Lu - Department of Electrical Engineering and Computer Science, University of Michigan - Ann Arbor, Michigan, United States - presents a Waterloo Institute for Nanotechnology (WIN) seminar titled "Memory and Computing Systems Based on Reconfigurable Materials: Merging Electronics with Ionics." Exponential growth of the semiconductor industry, historically driven by transistor scaling, is now facing fundamental challenges. In this talk, I will discuss an emerging class of devices that, by merging electronic with ionics, offer the potential to control the materialsβ electronic properties in-situ and have led to promising memory and circuit concepts. These devices exhibit history-dependent, resistive switching behavior and are termed memristors (memory + resistor) or resistive memory devices. I will discuss our efforts on the development and optimization of memristor devices and integrated systems, including techniques of controlling the dynamic ionic migration processes and associated modeling efforts. Detailed TEM studies have been carried out to capture the ionic migration process and verify the switching mechanism. Functional high-density crossbar arrays have been integrated directly on top of CMOS circuits using a back-endof-line (BEOL) process, enabling hybrid non-volatile memory and reconfigurable circuit applications. Properly tuned devices also exhibit incremental conductance changes that are analogous to the behaviors of biological synapses and are well suited for hardwarebased, bio-inspired neuromorphic logic systems. Prototype neuromorphic circuits based on memristor arrays have been shown to be able to perform tasks such as pattern recognition in an unsupervised fashion for intelligent sensing, analysis and other dataintensive applications. --- Visit our website: http://www.nano.uwaterloo.ca Like us on facebook: http://www.facebook.com/uwnano Follow us on twitter: http://twitter.com/WINano [90JpLOT3CPA] |
