Working Principles

The CAT28F001LI-12B utilizes flash EEPROM technology to store data. It employs a combination of floating-gate transistors and control circuitry to enable both erasing and programming operations. When data is written, charges are trapped in the floating gate, altering the transistor's behavior and storing the desired information. To erase data, the trapped charges are removed, resetting the transistor to its original state.
