Abstract for Presentation

Oxide-based Neuromorphic devices for Brain-like Computing

Our brain is an intelligent biological computer with a power consumption of only 20W, and neurons are the basic unit of our brain for memory and information processing. The development of new concept devices with synaptic/neuronal function is of great significance for "brain-like chip" and "brain-like computing". Recent researches showed that the multi-terminal ion-modulated transistors based on interface ion/electron modulation have great prospects in this field. In 2009, we successfully developed the first multi-terminal amorphous IGZO-based electric-double-layer transistor using solid electrolyte as the gate dielectric, and studied the application of such devices for artificial synapses/neurons. In recent 10 years, our research group has successfully realized the bionics of biological information processing functions such as short/long-term memory of biological synapses/neurons, spike time-dependent plasticity (STDP), high-pass filtering, dendritic dynamics algorithm and Photoelectric Leaky integrate and fire (LIF) visual perception. Our results provide a new material and device choice for ultra-low power brain dynamics computing and bionic perception.
