Memory Array To provide the greatest flexibility, the memory array of the AT25DF512C can be erased in three levels of granularity, including a full-chip erase. The size of the erase blocks is optimized for both code and data storage applications, allowing both code and data segments to reside in their own erase regions. Figure 5 shows each erase level.
