Abstract
The aim of this paper is to examine the reliability of erasable programmable read only memory (EPROM) and electrically erasable programmable read only memory (EEPROM) components subjected to the influence of gamma radiation. This problem is of considerable significance for both military industry and space technology. We present total dose results for the NM27C512 8F85 EPROM and M24128 – B W BN 5 T P EEPROM components. There is evidence that EPROM components radioactive reliability is better than that of EEPROM components. Furthermore, the changes EPROM's undergoes are reversible, so that after erasing process and reprogramming all EPROM components are fully functional. On the other hand, EEPROM's changes are irreversible and when subjected to the influence of gamma radiation, all EEPROM components become permanently nonfunctional. The obtained results are analyzed and explained via the interaction of gamma radiation with oxide layers.
