Working Principles

AT24C01BN-SH-T utilizes electrically controlled floating gate transistors to store and retrieve data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erasing process, allowing the transistor to return to its original state. The stored data can be accessed by applying appropriate voltage levels to the chip's pins.
