To simplify power‐gating requirements in ultra‐low‐power architectures, design strategies for low‐power non‐volatile flip‐flops (F/Fs) are sought, for which the utilisation of spintronic devices offers a promising option. A D F/F that utilises a five‐terminal spintronic device for non‐volatile state holding in an intrinsically self‐complementing fashion is introduced. This self‐complementing device can be exploited to reduce overhead interfacing circuitry in order to realise a compact ten transistors with one spintronic device D F/F with instant store and restore functionality, while consuming <9 µW of power.
