The most advanced form of ROM is?

A

PROM

B

RAM

C

EEPROM

D

Cache Memory

Correct Answer: C

EEPROM: Electrically erasable programmable read-only memory (EEPROM) is a special type of PROM 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 ROM, EEPROM is not as fast as RAM. EEPROM is similar to Flash Memory (sometimes called flash EEPROM). The principal difference is that EEPROM requires data to be written or erased one byte at a time whereas flash memory allows data to be written or erased in blocks. This makes flash memory faster.
