HSPICE macromodel of a PMA racetrack memory

Abstract

This paper introduces the HSPICE macromodel of a racetrack memory (also commonly known as a domain-wall memory). MATLAB is used to generate the HSPICE code and different features of a perpendicular magnetic anisotropy (PMA) racetrack memory are evaluated. The proposed model simulates the write, the read and the shift operations of a racetrack memory. A good agreement between the simulation results obtained from the proposed model and experimental data is achieved.
