Working Principles

The AT24C128W-10SC utilizes electrically controlled floating gate transistors to store and retrieve digital information. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during the erasing process, allowing the transistor to return to its original state. The stored data can be accessed by sending appropriate commands through the I2C interface.
