In this paper we compare six different multilevel flash cells, viz., common ground, DINOR, AND, AMG, split gate and NAND. The key conclusions are that the hot electron effect lends itself better than tunneling as the multilevel programming mechanism. The common ground cell is the most suitable for multilevel flash cells. The NAND architecture is the least favorable.
