Abstract

Brain-Like Device Built from Nanoparticle Atomic Switch Networks

In article number 2400360, Hirofumi Tanaka and co-workers demonstrate the synaptic plasticity of an Ag–Ag₂S nanoparticle-based memristor network, in which over a thousand interconnected atomic switches mimic biological learning. Short-term plasticity emerges through spontaneous conductance relaxation, while repeated pulse stimulation transitions the device into a state of long-term potentiation, analogous to memory formation. With a retention time of 40 minutes, this network also exhibits a forgetting process similar to human memory, advancing our understanding of neuromorphic systems and paving the way for hardware-based artificial neural networks.

纳米粒子原子开关网络构建的类脑装置的短期和长期记忆功能。板牙。12/2024)

在第2400360号文章中，Hirofumi Tanaka和他的同事展示了Ag-Ag2S纳米颗粒记忆电抗器网络的突触可塑性，其中超过1000个相互连接的原子开关模拟了生物学习。短期可塑性通过自发电导松弛产生，而反复的脉冲刺激将设备转变为长期增强状态，类似于记忆形成。该网络的保留时间为40分钟，也表现出类似于人类记忆的遗忘过程，促进了我们对神经形态系统的理解，并为基于硬件的人工神经网络铺平了道路。
