4. Memory Array
To provide optimal flexibility, the memory array of the AT45DB321D is divided into three levels of granularity comprising of
sectors, blocks, and pages. The “Memory Architecture Diagram” illustrates the breakdown of each level and details the
number of pages per sector and block. All program operations to the DataFlash occur on a page by page basis. The erase
operations can be performed at the chip, sector, block or page level.
