A Single Electron MOS Memory (SEMM), in which one bit of information is represented by storing only one electron, has been demonstrated at room temperature. The SEMM is a floating gate Metal-Oxide-Semiconductor (MOS) transistor in silicon with a channel width (about 10 nanometers) which is smaller than...http://www.google.de/patents/US6069380?utm_source=gb-gplus-sharePatent US6069380 - Single-electron floating-gate MOS memory
