Memory technologies continue to obtain favourable projections from the Semiconductor Roadmap under aggressive feature scaling. Currently, resistive memory (ReRAM) is regarded as a very promising emerging technology. There are different types of the resistive memories that operate by forming and breaking conduction pathways via different physical mechanisms. The central question addressed in this study was: what is the smallest volume of matter needed for resistive memory?
