Detailed explanation-1: -EEPROM (electrically erasable programmable read-only memory ) is a user-modifiable ROM. It can be erased and reprogrammed (written to) repeatedly by applying an electrical voltage that is higher than normal.
Detailed explanation-2: -PROM is a written type of ROM. This memory is written only once by the user and electrically programmed at that time. EPROM is a type of ROM that can be written and read optically.
Detailed explanation-3: -EPROM replaced ROM and PROM. After about 30 years of continued use, EPROMs were eventually replaced by electrically erasable programmable read-only memory (EEPROM) and flash memory. EEPROM is essentially an updated version of EPROM technology–the key difference is that EEPROM chips are electrically erasable.
Detailed explanation-4: -The major advantage of the EPROM and EEPROM over the ROM and PROM is that they can be erased and reprogrammed. The most significant difference between EPROM and EEPROM is that an EPROM is erased by using UV rays, while an EEPROM is erased by using electrical signals.
