The internal structure of each Flash bank represents a sector architecture for flexible
erase capability. The minimum erase width is always a complete sector, and sectors can
be erased separately or in parallel. Contrary to standard EPROMs, erased Flash
memory cells contain 0s.
The D-Flash bank is divided into more physical sectors for extended erasing and
reprogramming capability; even numbers for each sector size are provided to allow
greater flexibility and the ability to adapt to a wide range of application requirements.
