VARIABLE RESISTANCE MATERIALS WITH SUPERIOR DATA RETENTION CHARACTERISTICS CAPABLE OF PROVIDING A COMPOSITE NONVOLATILE MEMORY MATERIAL AND DEVICE SUITABLE FOR A HOT TEMPERATURE

摘要

PURPOSE: Variable resistance materials with superior data retention characteristics are provided to show a 10-year data retention temperature and data retention time under a hot temperature.;CONSTITUTION: A phase change component comprises Sb as a composite material. The Sb has an atomic concentration of 3 to 16% in the composite material. An inactive component is distributed in the phase change component. The inactive component comprises a dielectric material. The melting point of the inactive component is higher than the melting point of the phase change component.;COPYRIGHT KIPO 2011
