A semiconductor memory that utilizes changes in electrical resistance due to the application of voltage is called ReRAM (resistance-change memory). It is characterized by a non-volatile and reversible change in element resistance caused by voltage pulses.<\/p>\n\n\n\n

Morishita research group has developed the fabrication of a ReRAM (Resistance Random Access Memory) structure by anodizing both sides of an aluminum sheet, and filling the pores with nickel using electroplating technique. <\/p>\n\n\n\n

Since the porous alumina is transparent, this structure becomes a transparent nonvolatile memory by combining with a transparent electrode such as Indium Tin Oxide(ITO) or ZnO.<\/p>\n\n\n\n
