In most common logic gates based on transistors, different logic functions have to be realized by applying a large number of logic gates, which are capable of performing only one function. A promising approach to overcome this obstacle with the additional advantage of a nonvolatile output is a reconfigurable logic based on small arrays of magnetic tunnel junctions. Here, an approach utilizing an ion bombardment induced patterning of the reference layer is proposed where the same logic unit consisting of only two magnetic tunnel junctions can be used for the AND, OR, NAND, NOR, and X(N)OR, functions.
