摘要:
A resistance variable element includes a first electrode, a second electrode and an ion conductor layer interposed between the first and second electrodes. Metal ions supplied from the first electrode into the ion conductor layer accept electrons from the second electrode and are turned into metal. The so formed metal is precipitated to cross-link and interconnect the first and second electrodes to provide for voltage variations. The ion conductor layer has a stacked layer structure comprised of a first ion conductor layer formed by a compound containing oxygen and carbon and a second ion conductor layer formed by a metal oxide. The metal oxide that forms the second ion conductor layer includes at least one out of zirconium oxide and hafnium oxide.
