Magneto-Logic Device Based on a Single-Layer Magnetic Tunnel Junction

A magnetic tunnel junction (MTJ) element can compute Boolean functions and also store the output of its last operation. Therefore, the MTJ shows potential for a universal logic element to implement sequential-logic functions as well as combinatorial ones. The established magneto-logic element has been designed and fabricated based on a triple-layer MTJ. We present a novel magneto-logic structure that consists of a single-layer MTJ and a current driver, which requires less processing steps with enhanced functional flexibility and uniformity.
