Lithographic Graphitic Memories

Reported here are easily accessible memory devices based upon stripes of chemical vapor deposited (CVD) nanosized irregular discs of graphitic material that can be layered in stripes 95%, are shown to exhibit voltage-induced switching behavior, which can be used for two-terminal memories. These memories are stable, rewritable, and nonvolatile with ON/OFF ratios up to 10(7), switching times down to 1 mus (tested limit), and switching voltages down to 3-4 V. The major functional parameters of these lithographic memories are shown to be scalable with the devices' dimensions.
