MAGNETIC DEVICE FOR PERFORMING A LOGIC FUNCTION

摘要

The present invention relates to a device (9) for performing a "logic function", comprising a magnetic structure including: at least a first magnetoresistive stack (MTJ1) that includes a first ferromagnetic layer and a second ferromagnetic layer that are separated by a non-ferromagnetic interlayer, the hard ferromagnetic layer being trapped in a fixed magnetic state serving as reference; and at least a first (19) and a second (18) current line belonging to a first (N3) and a second (N2) metallization level respectively, each of said two lines generating a magnetic field in the vicinity of the first stack when an electrical current passes therethrough. The first and second lines (19, 18) are placed at different distances from the second layer, said distances being determined by the "logic function".
