EEPROM (Electrically Erasable Programmable Read-Only Memory) is non-volatile memory that can be reprogrammed electrically. It's most commonly used in microcontrollers that need to store small amounts of data and retrieve it later.

Unlike RAM, EEPROM is not erased by powering off the chip. This makes it a good choice for devices that need to remember data after a reset or power down condition, such as a password-protected money locker.

Unlike flash memory, EEPROM is programmed and erased in blocks of one byte at a time. This allows it to be very fast, but at the cost of a limited number of write cycles. Despite these drawbacks, EEPROM is still widely used in electronics and is found in many popular applications.
