3.
Memory Array
To provide optimal flexibility, the AT45DB161E memory array is divided into three levels of granularity comprising of
sectors, blocks, and pages.
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.
