Working Principles

The AT24C01A-10SC chip utilizes an array of floating-gate transistors to store data. When data is written, the charge is trapped in the floating gate, representing a logical "1." To erase the data, a high voltage is applied, removing the charge and returning the transistor to its original state (logical "0"). The stored data can be accessed by sending appropriate commands through the I2C interface.
