Working Principles

The AT24C01A-10SI-2.7 chip utilizes a floating-gate transistor structure to store data. When programming, an electric charge is applied to the floating gate, trapping electrons and altering the transistor's behavior. This trapped charge represents the stored data. To erase the data, a higher voltage is applied to remove the trapped charge, resetting the transistor to its original state.
