  • Abstract
    GexTe1-x/Sb2Te3 superlattice topological-switching random access memory (TRAM) was developed. Set and reset currents of 55 μA, the lowest for an ULSI-grade device, were obtained. TEM analyses of the Ge-Te structures and novel superlattice fabrication enabled us to reveal the retention, endurance, and electrical characteristics of TRAM for the first time.
