Working Principles

The CAT93C56XI-T2 utilizes a floating-gate transistor structure to store and retrieve digital information. When data is written, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erasure 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.
