International Symposium on VLSI Technology, Systems and Application (VLSI-TSA), Hsinchu, TAIWAN, APR 25-27, 2016 ; International audience ; Various RRAM concepts are currently being investigated (Oxide based RAM, Conductive Bridge RAM), all showing pros and cons depending on the architecture and memory stack. As the specifications are strongly application-dependent, it is likely that the RRAM technology will be bound to a specific market segment. In this paper, we discuss the potential of RRAM for non-volatile memory applications, among them: storage class memory, embedded memory, programmable logic, mass storage and neuromorphic applications. By means of experimental studies and simulations, we analyze the role of the integrated materials on the memory performances and reliability and try to propose optimized stacks suitable for each targeted application.
