Temporal memory with magnetic racetracks
IEEE Journal on Exploratory Solid-State Computational Devices and …, 2020•ieeexplore.ieee.org
Race logic is a relative timing code that represents information in a wavefront of digital
edges on a set of wires in order to accelerate dynamic programming and machine learning
algorithms. Skyrmions, bubbles, and domain walls are mobile magnetic configurations
(solitons) with applications for Boolean data storage. We propose to use current-induced
displacement of these solitons on magnetic racetracks as a native temporal memory for race
logic computing. Locally synchronized racetracks can spatially store relative timings of …

Race logic is a relative timing code that represents information in a wavefront of digital edges on a set of wires in order to accelerate dynamic programming and machine learning algorithms. Skyrmions, bubbles, and domain walls are mobile magnetic configurations (solitons) with applications for Boolean data storage. We propose to use current-induced displacement of these solitons on magnetic racetracks as a native temporal memory for race logic computing. Locally synchronized racetracks can spatially store relative timings of digital edges and provide nondestructive readout. The linear kinematics of skyrmion motion, the tunability and low-voltage asynchronous operation of the proposed device, and the elimination of any need for constant skyrmion nucleation and annihilation make these magnetic racetracks a natural memory for low-power, high-throughput race logic applications.
