Working Principles

The FT93C46A-UDR-B utilizes electrically controlled floating gate transistors to store and retrieve data. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during the erasing process, allowing the transistor to return to its original state. The stored data can be accessed by applying appropriate voltage levels to the chip's pins.
