Memristive devices for bio-inspired electronics — •Hermann Kohlstedt — Chair of Nanoelectronics, Faculty for Electrical Engineering and Information Technology, Kiel University, Germany

Information processing in biological nerve system is characterized by highly parallel, energy efficient and adaptive architectures in contrast to clock driven digital Turing machines. Even simple creatures outperform supercomputers when it comes to pattern recognition, failure tolerant systems and cognitive tasks. Fundamental building blocks leading to such remarkable properties are neurons as central processing units, which are (with variable strengths) interconnected by synapses to from a complex dynamical three dimensional network. The field of neuromorphic engineering aims to mimic such biological inspired information pathways by electronic circuitries. The advent of memristive devices opened novel pathways to mimic basal synaptic functionalities as e.g., spike-time-depended plasticity (STDP). In the tutorial I will explain how such local learning mechanisms are mimicked by memristive. In addition I will address the opportunities and challenges to integrate memristive devices as a part of cognitive electronic circuits, in particular for the interesting field of non-linear dynamics in the context with correlation and synchronization phenomena in nerve systems.
