Abstract

AbstractThis article (DOI: 10.1002/inf2.12380) comprehensively reviews the recent progress in artificial synaptic and spiking neuron devices for neuromorphic computing based on (Hf,Zr)O2‐based ferroelectrics. The actual human brain consists of neurons, axons, and synapses. Simply explain their functions, neurons communicate with each other via electrical events called action potential and chemical neurotransmitters. At the junction between two neurons which is called a synapse, an action potential causes one side of the neuron to release a chemical neurotransmitter. Thus, we intended to mimic the basic element of the human brain and its functions by utilizing our ferroelectric devices. The background consists entirely of two parts (i.e biological neural network (Upper part) and integrated semiconductor chips (Bottom part). In the center of the cover image, we highlighted fluorite‐structured ferroelectrics by emitting lights. It should be noted that the light here is nothing more than intended to emphasize fluorite structure. image
