Graphene oxide based memristor
MetadataShow full item record
A memristor is the memory extension to the concept of resistor. With unique superior properties, memristors have prospective promising applications in non‐volatile memory (NVM). Resistive random access memory (RRAM) is a non‐volatile memory using a material whose resistance changes under electrical stimulus can be seen as the most promising candidate for next generation memory both as embedded memory and a stand‐alone memory due to its high speed, long retention time, low power consumption, scalability and simple structure. Among carbon‐based materials, graphene has emerged as wonder material with remarkable properties. In contrast to metallic nature of graphene, the graphene oxide (GO) is good insulating/semiconducting material and suitable for RRAM devices. The advantage of being atomically thin and the two-dimensional of GO permits scaling beyond the current limits of semiconductor technology, which is a key aspect for high‐density fabrication. Graphene oxide‐based resistive memory devices have several advantages over other oxide materials, such as easy synthesis and cost‐effective device fabrication, scaling down to few nanometre and compatibility for flexible device applications. In this chapter, we discuss the GO‐based RRAM devices, which have shown the properties of forming free, thermally stable, multi‐bit storage, flexible and high on/off ratio at low voltage, which boost up the research and development to accelerate the GO‐based RRAM devices for future memory applications.
