ABSTRACT:
An apparatus and method of erasing memory cells while preventing overerasure of the memory cells is disclosed. By applying a large voltage across the floating gate of the memory cells, charge is removed from the floating gate. Once sufficient charge is removed from the floating gates of the memory cells to render them erased, a stop transistor halts the erasure process, thus preventing the overerasure of memory cells.
