4. Memory Array

To provide the greatest flexibility, the memory array of the Atmel® AT25DF081A can be erased in four levels of

granularity including a full chip erase. In addition, the array has been divided into physical sectors of uniform size,

of which each sector can be individually protected from program and erase operations. The size of the physical

sectors is optimized for both code and data storage applications, allowing both code and data segments to reside

in their own isolated regions. The Memory Architecture Diagram illustrates the breakdown of each erase level as

well as the breakdown of each physical sector.
