ABSTRACT:
A method for insuring that an erase operation practiced on a block of flash EEPROM transistors is carried out reliably including the steps of: writing whenever the erasure of a block of the flash EEPROM array is to commence to a position in the array to indicate that an erasure of the block has commenced, writing whenever the erasure of a block of the flash EEPROM array is complete to the position in the array to indicate that an erasure of the block has been completed, testing to determine any positions in the array which indicate that an erasure of a block has commenced but not been completed upon applying power to the flash EEPROM array, and reinitiating an erase if any positions in the array exist which indicate that an erasure of a block has commenced but not been completed.
