EEPROMs

EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory (meaning that its data is retained even after power is turned off) which can be repeatedly erased and reprogrammed by the application of an electrical charge without removing them from the circuit. EEPROM chip allows individual bytes to be read, erase, and re-write whereas other non-volatile memories needs entire chip to be erased at one time. EEPROMs used to store small amount of information in a system. Serial interface EEPROM and Parallel interface EEPROM are the different types or EEPROMs available.
