At this week's VLSI Technology Symposium (Honolulu, Hawaii, USA), imec presents significant improvements in performance and reliability of RRAM cells by process improvements and clever stack-engineering, and imec introduces a new modeling approach increasing the fundamental understanding of RRAM process technology. These achievements pave the way towards scalability and manufacturability of RRAM technology.
RRAM is a promising concept for future non-volatile memories because of its high speed, low energy operation, superior scalability, and compatibility with CMOS technology. Its operation relies on the voltage controlled resistance change of a conductive filament in the dielectric of a Metal/Insulator/Metal (MIM) stack.
