제목 Nonvolatile Resistive Random Access Memory based on Polyimide/Graphene Oxide Nanocomposite
초록 Recently, resistive random access memory (RRAM) has been studied as a next generation nonvolatile memory, because it has simple metal-insulator-metal structure and excellent operating characteristics. In this work, a graphene oxide-based polyimide (PI-GO) nanocomposite was prepared and later used as memory layer (composed of a GO and a PI derived from rel-(1'R,3S,5'S)-spiro[furan-3(2H),6'- [3]oxabicyclo[3.2.1]octane]-2,2',4',5(4H)-tetrone (DAn) and 2,6-diaminoanthracene (AnDA)) in the fabrication of a RRAM device. The device showed write-once-read-many-times (WORM) characteristic with a high ON/OFF current ratio of 3.41 x 108. This excellent current ratio was attributed to the high charge trapping ability of GO. In addition, the device had good endurance until the 100th cycle and retention time during 1500 s. These results suggested that PI-GO as an active layer in RRAM is an attractive candidate for applications in next generation nonvolatile memory.
