Working Principles

The FT24C04A-UMR-B utilizes a combination of electrically erasable floating-gate transistors and a control circuitry to store and retrieve data. When data is written, the control circuitry applies a high voltage to the floating gate, trapping electrons and altering the transistor's conductive properties. To erase the data, a higher voltage is applied to remove the trapped electrons, restoring the transistor to its original state.
