4. Memory Array
To provide the greatest flexibility, the memory array of the AT25DF321A 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.
