"Memristive Nanodevices and Arrays for Brain-inspired Computing and Beyond"

Abstract: Developing electronics beyond Moore's Law requires revolutionary vision in novel devices, disruptive technologies, new materials and alternative computer architecture. Memristor (resistance switch) is an emerging nanoelectronic device that uses resistance states to represent digital or analog information. In this talk, I will first describe our recent efforts in developing high performance HfO2 and SiO2 based memristive devices and arrays, including 2 nm scaling and 8 layer stacking. I will then showcase the integration of large memristor arrays (128×64) and applications in analog image processing and multilayer neural network classification. After introducing our synaptic and neural emulators with memristors, I'll finally briefly discuss other applications such as memristive radiofrequency switches and true random number generators.
