A Dual Magnetic Tunnel Junction‐Based Neuromorphic Device
Advanced Intelligent Systems, Volume 2, Issue 12, December 2020., 2020 A memristive device based on a dual‐domain and dual magnetic tunnel junction is demonstrated, utilizing spin‐transfer torque (STT), to drive a domain wall switching. Multi‐level resistance can be modulated in an analog manner by the pulsed current characteristics paving a way for developing STT‐based energy‐efficient neuromorphic systems.
