Working Principles

CAT24C32VP2I-GT3 utilizes EEPROM technology, which is based on floating gate transistors. The stored data is represented by the presence or absence of an electrical charge on these floating gates. To write data, a high voltage is applied to the gate, allowing electrons to tunnel through a thin oxide layer and modify the charge. Reading data involves sensing the charge state of the floating gates.
