Working Principles

AT93C57W-10SI utilizes a combination of floating gate transistors and electronic switches to store and retrieve data. 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 then be read by applying appropriate voltage levels to the chip's pins.
