Abstract:
A magnetoresistive random access memory (MRAM) cell includes a bottom electrode, a magnetic tunnel junction structure, a bipolar tunnel junction selector; and a top electrode. The tunnel junction selector includes a MgO tunnel barrier layer and provides a bipolar function for putting the MTJ structure in parallel or anti-parallel mode.
