Abstract

An in-situ in-memory implication gate is disclosed. The gate include a memory cell. The cell includes a first voltage source, a second voltage source lower in value than the first voltage source, a first and second magnetic tunneling junction devices (MTJ) selectively juxtaposed in a series and mirror imaged relationship between the first and second sources, each having a pinned layer (PL) in a first direction and a free layer (FL) having a polarity that can be switched from the first direction in which case the MTJ is in a parallel configuration presenting an electrical resistance to current flow below a first resistance threshold to a second direction in which case the MTJ is in an anti-parallel configuration presenting an electrical resistance to current flow higher than a second resistance threshold, and further each having a non-magnetic layer (NML) separating the PL from the FL.
