Working Principles

The AT29LV256-20TI utilizes a floating-gate transistor technology to store data. 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 data can be accessed by applying appropriate voltage levels to the device's pins.
