Memory Array

To provide optimal flexibility, the AT45DB081E memory array is divided into three levels of granularity comprising of

sectors, blocks, and pages. Figure 3-1, Memory Architecture Diagram illustrates the breakdown of each level and details

the number of pages per sector and block. Program operations to the DataFlash can be done at the full page level or at

the byte level (a variable number of bytes). The erase operations can be performed at the chip, sector, block, or page

level.
