Complementary magnetic memory cell
A complementary magnetic memory cell includes: a heavy metal film or an antiferromagnetic film, a first magnetic tunnel junction, a second magnetic tunnel junction, a first electrode, a second electrode, a third electrode, a fourth electrode, and a fifth electrode; wherein the first magnetic tunnel junction and the second magnetic tunnel junction are fabricated above the heavy metal film or the antiferromagnetic film; the first electrode, the second electrode and the third electrode are fabricated under the heavy metal film or the antiferromagnetic film; the fourth electrode is fabricated above the first magnetic tunnel junction, and the fifth electrode is fabricated above the second magnetic tunnel junction; to store one bit of data, the first magnetic tunnel junction and the second magnetic tunnel junction are arranged in a pair of complementary resistance states, wherein one magnetic tunnel junction is set to a high resistance state and the other remains unchanged.
