Abstract
A Graphene Flash Memory (GFM) device is disclosed. In general, the GFM device includes a number of memory cells, where each memory cell includes a graphene channel, a graphene storage layer, and a graphene electrode. In one embodiment, by using a graphene channel, graphene storage layer, and graphene electrode, the memory cells of the GFM device are enabled to be scaled down much more than memory cells of a conventional flash memory device. More specifically, in one embodiment, the GFM device has a feature size less than 25 nanometers, less than or equal to 20 nanometers, less than or equal to 15 nanometers, less than or equal to 10 nanometers, or less than or equal to 5 nanometers.
