Abstract: There is provided a structure of a nano memory system. The disclosed unit nano memory cell comprises a single isolated nanoparticle placed on the surface of a semiconductor substrate (301) and an adjacent nano-Schottky contact (303). The nanoparticle works as a storage site where the nano-Schottky contact (303) works as a source or a drain of electrons, in or out of the semiconductor substrate (301), at a relatively small voltage. The electric current through the nano-Schottky contact (303) can be turned on (reading 1) or off (reading 0) by charging or discharging the nanoparticle. Since the electric contact is made by a nano-Scottky contact (303) on the surface and the back contact of the substrate (301), and the charge is stored in a very small nanoparticle, this allows to attain the ultimate device down-scaling. This would also significantly increase the number of nano memory cells on a chip.
