Working Principles

The AT24C128-10PC utilizes EEPROM technology, which stores data using electrically isolated floating-gate transistors. When data needs to be written, an electrical charge is applied to the floating gate, altering its threshold voltage. This allows the transistor to represent either a "0" or a "1". Reading the stored data involves sensing the threshold voltage of each transistor.
