Abstract

Aspects of the present disclosure are directed to magnetic tunnel junction (MTJ) structures comprising multiple MTJ bits connected in series. For example, a magnetic tunnel junction (MTJ) stack according to the present disclosure may include at least a first MTJ bit and a second MTJ bit stacked above the first MTJ bit, and a resistance state of the MTJ stack may be read by passing a single read current through both the first MTJ bit and the second MTJ bit.
