Working Principles

AT28C010-12PU utilizes a floating-gate transistor technology 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 retained for an extended period, allowing the stored data to persist even when power is removed. During read operations, the transistor's behavior is determined by the presence or absence of charge in the floating gate, enabling data retrieval.
