Abstract:
1. A device for performing a “logic function” including a magnetic structure comprising: at least one first magnetoresistive stack including a first ferromagnetic layer and a second ferromagnetic layer separated by a non-ferromagnetic interlayer, at least one first current line situated in the vicinity of the first magnetoresistive stack and generating in the vicinity of the first stack a magnetic field when an electric current passes through it, wherein, for said at least one first magnetoresistive stack, said first line includes at least two current input points such that two currents are added together in said first line, with a sum of both said currents being determined by said logic function, and wherein said first line is connected to at least one other current line belonging to a metallization level that is different from a metallization level of the first line, with both lines being connected by an interconnection conductive line and a point of connection between said interconnection line and said first line forming one of the two current input points.
