Abstract
A memory device using vertical nanotubes includes an array of first electrodes arranged in strips in a first direction, a dielectric layer deposited on the array of first electrodes, the dielectric layer having a plurality of holes arranged therein, an array of nanotubes for emitting electrons, the array of nanotubes contacting the array of first electrodes and vertically growing through the plurality of holes in the dielectric layer, an array of second electrodes arranged in strips in a second direction on the dielectric layer, the array of second electrodes contacting the array of nanotubes, wherein the second direction is perpendicular to the first direction, a memory cell positioned on the array of second electrodes for trapping electrons emitted from the array of nanotubes, and a gate electrode deposited on an upper surface of the memory cell for forming an electric field around the array of nanotubes.
