An input interface for all‐spin logic (ASL) circuits is proposed, which is composed of magnetic tunnel junction (MJT) and metal wires that are used for transmitting electrical signals. The proposed input interface can shorten the length of non‐magnetic channel and avoid the complex fan‐out structure, and is fit for the circuits that need multiple same input signals. Moreover, based on the ASL minority gate and inverter, two kinds of XOR gates are designed. Compared with the XOR gate without input interface, the XOR gate using input interface possesses lower energy dissipation and higher reliability. Using coupled spin‐transport/magneto‐dynamics models, validity of the input interface and XOR gates are demonstrated. This work provides an interesting approach for the design of large‐scale ASL circuits that contain many identical input ports.
