EEPROM

EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory that retains data even when power is removed and can be electrically erased and reprogrammed. Unlike regular ROM, EEPROM allows individual bytes or small blocks to be erased and rewritten without removing the chip from the circuit. It is commonly used to store configuration settings, calibration data, and small programs in microcontrollers and embedded systems. EEPROM has slower write/erase speeds compared to RAM but offers reliable long-term data storage for applications requiring occasional updates.
