Working Principles

The AT24C1024BN-SH-B utilizes an electrically erasable floating-gate transistor technology to store and retrieve data. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during an erase operation, allowing the transistor to return to its original state. The stored data can be accessed by sending appropriate commands through the serial interface.
