Abstract
A method of erasing a block of flash memory cells by applying a ramped gate erase voltage to the block of memory cells. When an erase verify of the block of memory cells indicates that erasure has not been successfully completed another erase voltage with a greater absolute value than the initial erase voltage can be applied to the block of memory cells until erasure is complete.
