Abstract: A type of EEPROM with the FLOTOX structure is intoduced. The main reliability issues of the FLOTOX EEPROM are studied, i.e., the degradation of the programming windows, the degradation of the retention characteristics and the time dependent dielectric breakdown(TDDB). The reliability of FLOTOX is correlative to the quality of the tunnel oxide. The degradation of FLOTOX depends on the trap charges which come from the tunnel oxide, which is proved by experimental results.

Key words: FLOTOX, EEPROM, degradation, reliability
