2. Programming and erase time do not include data transfer time.
3. This value indicates the minimum number of which the flash memory are
reprogrammed with all characteristics guaranteed. (The guaranteed value ranges from
1 to the minimum number.)
4. This value indicates the characteristics while the flash memory is reprogrammed within
the specified range (including the minimum number).
5. Reprogramming count in each erase block.
