To provide the greatest flexibility, the memory array of the AT26DF161 can be erased in four lev-
els 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.
