ABSTRACT:
A method for erasing memory cells in a memory array, the method including applying an erase pulse to bits of a cell ensemble of a memory cell array, and performing an erase verification operation only on a subgroup of the cell ensemble being erased to check if the memory cells threshold voltage (Vt) has been lowered to an erase verify (EV) voltage level.
