Working Principles

The AT27BV1024-12JU utilizes a floating-gate transistor technology to store and retrieve digital information. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during an erase operation, allowing the transistor to return to its original state. The stored information can be accessed by applying appropriate voltage levels to the address and control inputs.
