Working Principles

The AT24C32D-MAHM-T utilizes electrically controlled floating gate transistors 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 the erase process, allowing the transistor to return to its original state. The stored data can be accessed by providing the appropriate memory address through the I2C interface.
