EEPROM (Electrically-Erasable Programmable Read-Only Memory) is a persistent memory that allows you to store up to 1024 bytes (1 kilobyte) in your microncontroller, even when it's turned off. Data is created in them by electrical pulses and a grid. EEPROM requires fewer I/O lines from the microcon-troller which significantly reduces the overall system cost and board space.
