Memory Array
To provide the greatest flexibility, the memory array of the AT25SL321 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. The Memory Architecture Diagram
illustrates the breakdown of each erase level.
