EEPROM

====**E **lectrically **E **rasable **P **rogrammable **R **ead-**O **nly **M **emory and is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data. EEPROM is a special type of memory that can be erased by exposing it to an electrical charge. Like other types of PROM, EEPROM retains its contents even when the power is turned off. Also like other types of memory, EEPROM is not as fast as RAM. ====

====EEPROM chips require considerable time to alter a location, writing takes over 100 times longer than reading. EEPROM chips are widely used for non-volatile storage in consumer applications, such as SIM cards in mobile phones, memory cards in digital cameras and memory in MP3 players. ====
