ABSTRACT:
Every time a program pulse is applied, transition in source potential connected to a selected cell is detected and the source potential is clamped. When the source potential exists an overbit generation detection level, transition in threshold voltage of a non-selected cell connected to the same sub bit as the selected cell and existing in a different page than the selected cell is detected, and the threshold voltage is recovered. Threshold voltage verifying operation is performed on the same page as the selected cell.
