摘要：
Techniques, apparatus and circuits based on magnetic or magnetoresistive tunnel junctions (MTJs). In one aspect, a programmable circuit device can include a magnetic tunnel junction (MTJ); a MTJ control circuit coupled to the MTJ to control the MTJ to cause a breakdown in the MTJ in programming the MTJ; and a sensing circuit coupled to the MTJ to sense a voltage under a breakdown condition of the MTJ.
