8 / 77 page  7 AT25QL641 DS-25QL641–130E–10/2018 3. Memory Array To provide the greatest flexibility, the memory array of the AT25QL641 can be erased in four 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 3-1 illustrates the the breakdown of each erase level. Figure 3-1.
