Memory Array
To provide optimal flexibility, the AT45DB321D memory array is divided into three levels of granularity comprising sectors,
blocks, and pages. The
pages per sector and block. All program operations to the DataFlash device occur on a page-by-page basis. The erase
operations can be performed at the chip, sector, block, or page level.
