神经形态计算捕获了大脑的典型神经行为,是超越冯·诺依曼计算机架构的有希望的候选者,具有低功耗和高并行性的特点。神经元侧抑制特征与生物感受野密切相关,对于神经系统及其神经形态硬件对应物中的神经元竞争至关重要。磁畴壁-磁隧道结(DW-MTJ)神经元是一种新兴的自旋电子人工神经元器件,表现出内在的横向抑制。这项工作讨论了 DW-MTJ 神经元的侧抑制机制,并通过微磁模拟表明 Dzyaloshinskii-Moriya 相互作用 (DMI) 可以有效增强侧抑制。
Neuromorphic computing captures the quintessential neural behaviors of the brain and is a promising candidate for the beyond-von Neumann computer architectures, featuring low power consumption and high parallelism. The neuronal lateral inhibition feature, closely associated with the biological receptive field, is crucial to neuronal competition in the nervous system as well as its neuromorphic hardware counterpart. The domain wall - magnetic tunnel junction (DW-MTJ) neuron is an emerging spintronic artificial neuron device exhibiting intrinsic lateral inhibition. This work discusses lateral inhibition mechanism of the DW-MTJ neuron and shows by micromagnetic simulation that lateral inhibition is efficiently enhanced by the Dzyaloshinskii-Moriya interaction (DMI).
