Working Principles

The AT27C1024-12VC is based on the principle of electrically programmable read-only memory (EPROM). It uses a floating-gate transistor structure to store data. During programming, electrical charges are trapped in the floating gate, altering the transistor's behavior and storing the desired data. Once programmed, the data remains intact until the next programming cycle.
