To provide the greatest flexibility, the memory array of the AT26DF161A can be erased in four
levels of granularity including a full chip erase. In addition, the array has been divided into phys-
ical sectors of various sizes, of which each sector can be individually protected from program
and erase operations. The sizes of the physical sectors are optimized for both code and data
storage applications, allowing both code and data segments to reside in their own isolated
regions.
