Working Principles

The AT17C020A-10JC utilizes a floating-gate transistor technology to store digital information. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges remain even when power is removed, allowing the stored data to be retained. During read operations, the transistor's behavior is determined by the presence or absence of charges in the floating gate, enabling the retrieval of stored information.
