Abstract :
Reliability issues for flash electrically erasable programmable read-only memories are reviewed. The reliability of both the source-erase type (ETOX) flash memory and the NAND structure EEPROM are discussed. Disturbs during programming, write/erase endurance, charge loss of both devices are reviewed, and the reliability of the tunnel oxide and the interpoly dielectric are described. It is shown that bipolarity F-N programming/erase, which is used in the NAND EEPROM, improves the charge to breakdown and decreases the stress-induced leakage current
