This presentation is part of the Photonics & Electronics Research Lab Seminar series. The seminar will be presented by Dept of EEE Research Fellow, Omid Kavehei titled 'Associative Capacitive Networks based on Nanoscale Complementary Resistive Switches'.
In this talk, Omid will discuss background and known applications in memristive electronics. He will then present ongoing research and challenges in designing nanocrossbar-based systems including associative capacitive networks.
The continuous development of new materials in the field of memory applications involves both new approaches within chip architecture and information processing. Advantages of Resistive Switch-based memories are the feasibility of highly parallel processing, high scalability of hardware, CMOS compatible technology and wide interconnectivity as well as low energy consumption which is the foundation for unconventional computing such as neuromorphic and stochastic computing. Associative memories allow architectures for wide range of applications including on-chip image and speech recognition, intelligent database search engines, and flexible decision making processes. The recently introduced Complementary Resistive Switch (CRS) overcomes parasitic current path problem of passive memory arrays and reveals, besides the memory feature, opportunities for neuromorphic functions. Apart from memory and logic applications CRS based Resistive Random Access Memories (RRAMs) facilitate, in combination with the capacity based nondestructive readout approach, an implementation of a nonvolatile associative memory. In addition, the excellent switching behavior of materials such as TaOx makes a reliable CRS implementation possible and therefore highly attractive for associative capacitive networks.
Omid Kavehei (Member, IEEE) received his PhD from the University of Adelaide in 2012, with the Dean’s Commendation for Doctoral Excellence. In 2011, he took up an appointment as a Research Fellow at the University of Melbourne. In 2009 and 2010, he spent eight months in South Korea as a Visiting Scholar to develop his research career in the field of memristive electronics. He was a recipient of the Endeavour International Postgraduate Research Scholarship, D. R. Stranks Travelling Fellowship (UoA), Simon Rockliff Scholarship (DSTO), Research Abroad Scholarship (UoA), and the World Class University (South Korean program).
