G-ReRAM project aims to develop an innovative resistive memory (ReRAM) cell architecture where graphene will improve the cell’s performance. Graphene possesses a high electronic conductivity, is comparatively inert in a chemical sense and offers a perfect termination of ionic activity at the electrode/electrolyte interface at rest. Moreover, it is sufficiently thin to allow ion migration under high electric field conditions. ReRAM cells are the most emerging memory devices for technology nodes <16 nm according to the latest edition of the international technology roadmap for semiconductors (ITRS). The major two-terminal ReRAM cells are the vacancy change (VCM) and electrochemical metallization cells (ECM). It is well known that the resistance switching in these devices is governed by the electrochemical interaction between the terminal electrodes and the solid-state electrolyte material. The chemical instability and the presence of (electro)chemical potential gradients at the electrode/electrolyte interface are the main issues for ReRAM cells that affect both their performance and reliability. By inserting graphene as intermediate layer between the electrodes and the electrolyte or using graphene as electrode we can control the electrochemical interaction at this interface. In this context, G-ReRAM is expected to provide a breakthrough in the current ReRAM technology and also is targeting to demonstrate ReRAM memory cells with graphene-modified electrodes having dimensions below 30nm. This will be achieved by using the new e-beam lithography tool installed recently at the premises of the Greek project coordinator. The collaborating teams have expertise in memory devices and graphene transfer as well as with industrial partners. The proposed project is expected to have strong impact on the graphene technological applications as well as on the ReRAM technology. For these reasons the project is supported by the German manufacturer Aixtron, which will join the G-ReRAM consortium in the next phase.
