The basic concept behind resistive memory devices is the insertion of a dielectric material--one that won't normally conduct electricity--between two wires.
a narrow conduction path can be formed through the dielectric material. The presence or absence of these conduction pathways can be used to represent the binary 1s and 0s of digital data.
Research with a number of dielectric materials over the past decade has shown that such conduction pathways can be formed broken and reformed thousands of times,
At the same time, the researchers also conducted countless tests to compare the performance of silicon oxide memories with competing dielectric RRAM technologies."
