Abstract

The present disclosure proposes implementation of a three-memristor synapse where an adjustment of synaptic strength is based on Spike-Timing-Dependent Plasticity (STDP) with dopamine signaling.

Description

technical field [0001] In general, certain embodiments of the present invention relate to neural system engineering and, in particular, to designing triple memristor synapses that support Spike-Timing-Dependent Plasticity (STDP) and dopamine signaling. Background technique [0002] Nervous system engineering has received much attention in recent years. Inspired by the extraordinary flexibility and power efficiency of biological brains, nervous systems can be used in many applications such as pattern recognition, machine learning, and motor control. One of the biggest challenges for practical neural system implementations is hardware density. Neurons and synapses are the two fundamental components of the nervous system, which may number in the billions. For example, the human brain has about 10 11 neurons, and the number of synapses is 10 greater 3 to 10 4 times. [0003] Therefore, to implement practical neural systems, synaptic hardware is required to be very area and...
