We have realized Si nanocrystal memory cells in which the Si dots have been deposited by chemical vapor deposition (CVD) on the tunnel oxide and then covered by a CVD control oxide. In this paper we report a study on the potential of this type of cells for multi-bit storage. In particular, the possibilities offered by these devices from the point of view of program/erase mechanisms, endurance, and charge retention are shown and discussed.
