Abstract
A memory device includes a plurality of memory cells arranged in series in the semiconductor body, such as a NAND string, having a plurality of word lines. A selected memory cell is programmed by hot carrier injection using a boosted channel potential to establish the heating field. Boosted channel hot carrier injection can be based on blocking flow of carriers between a first side of a selected cell and a second side of the selected cell in the NAND string, boosting by capacitive coupling the first semiconductor body region to a boosted voltage level, biasing the second semiconductor body region to a reference voltage level, applying a program potential greater than a hot carrier injection barrier level to the selected cell and enabling flow of carriers from the second semiconductor body region to the selected cell to cause generation of hot carriers.
