An EEPROM memory chip is ...

• A. A volatile memory that loses data when power is off.
• B. An integrated-circuit memory chip with an internal switch to erase and rewrite contents electrically.
• C. A processor.
• D. A magnetic storage device.

Answer: (B)

EEPROM is non-volatile memory that can be electrically erased and rewritten. Its defining feature is the internal circuitry that lets you erase and reprogram its contents with electrical signals while the chip remains in the circuit. This lets data be retained without power and updated as needed.

That’s why this description fits EEPROM: it’s an integrated-circuit memory with an internal mechanism for electrically erasing and rewriting data. It isn’t volatile memory (which loses data when power is removed), it isn’t a processor (which executes instructions), and it isn’t magnetic storage (which uses magnetic domains).
