Working Principles

The AT24C02N-10SI uses a combination of electrically controlled transistors and floating gate technology to store and retrieve data. When data is written to the EEPROM, an electric charge is trapped in the floating gate, altering the transistor's behavior and storing the information. This stored charge can be read back later by applying appropriate voltages to the memory cells.
