Another phenomenon which helps with this is overerasing. If the erase cycle is applied to an already-erased cell, it leaves the floating gate positively charged, thus turning the memory transistor into a depletion-mode transistor. To avoid this problem, some devices, for example Intel’s original ETOX devices, first program all cells to 0’s before erasing them to 1’s. In later devices this problem was solved by redesigning the cell to avoid excessive overerasing, however even with this protection there is still a noticeable threshold shift when a virgin cell is programmed and erased.
