Abstract:
In a Single-Electron Memory Cell (SEMC) one bit of information is represented by the excess or shortfall of a small (¡Ý1) number of electrons on the floating gate (FG). We present experimental results on the all-metallic FG memory devices fabricated using aluminum tunnel junction technology [3] with variable barrier separating FG and its control gate (CG). We report the operation of SEMC in one electron mode.Experimental results are compared with calculations and a very good match is observed. We discuss several regimes of SEMC operation and various methods to improve the performance of this type of memory.
