Abstract Spin–orbit torque (SOT)‐induced magnetization switching exhibits chirality (clockwise or counterclockwise), which offers the prospect of programmable spin‐logic devices integrating nonvolatile spintronic memory cells with logic functions. Chirality is usually fixed by an applied effective magnetic field in reported studies. Herein, utilizing in‐plane layer that also switchable SOT, a perpendicular exchange‐coupled can be reversed purely electrical way. In single Hall bar device designed from this multilayer structure, three gates including AND, NAND, and NOT are reconfigured, opens gateway toward practical devices.
