Abstract

With scalability and diverse device behavior, memristors present potential for executing neuromorphic computation with lower hardware cost and power consumption. However, Low consistency currently limited the application of memristors. Herein, we report a VO₂-based memristor fabricated through magnetron sputtering and multiple annealing processes, exhibiting extremely low in both cycle-to-cycle (C2C) and device-to-device (D2D) variations. Further, a Hodgkin-Huxley model neuron circuit based on the extremely high consistency of the devices is established, which achieves auditory neuron perception simulation through spatiotemporal processing of spike signals, allowing for clear differentiation of sound source direction and displaying patterns akin to biological behavior. This easily implemented and highly consistent artificial neuron offers a promising approach for the development of next-generation artificial auditory systems.

用于人工听觉神经元的高一致性VO2忆阻器

忆阻器具有可扩展性和多样化的设备行为，具有以更低的硬件成本和功耗执行神经形态计算的潜力。然而，低一致性目前限制了忆阻器的应用。在此，我们报道了一种通过磁控溅射和多次退火工艺制造的基于VO2的忆阻器，该忆阻器在循环到循环（C2C）和器件到器件（D2D）的变化都极低。此外，基于设备的极高一致性，建立了霍奇金-赫胥黎模型神经元电路，通过对尖峰信号的时空处理，实现了听觉神经元感知模拟，可以清晰区分声源方向并显示类似于生物行为的模式。这种易于实现且高度一致的人工神经元为开发下一代人工听觉系统提供了一种很有前途的方法。
