Experimental demonstration of magnetic tunnel junction-based computational random-access memory
“In this work, a CRAM array based on magnetic tunnel junctions (MTJs) is experimentally demonstrated. First, basic memory operations, as well as 2-, 3-, and 5-input logic operations, are studied. Then, a 1-bit full adder with two different designs is demonstrated.”

So, this is experimentally demonstrated, yet, only at small scale.
