Different configurations of GeTe/Sb$_{2}$Te$_{3}$ superlattices are studied using the non-equilibrium Green's function approach. Our electronic transport simulations calculate the coupling parameter for the high resistance covalent state, to $97 \\%$ that of the stable low resistance resonant state, maintaining the ON/OFF ratio of 100 for a reliable read operation.
