Notes: 1. Write time and erase time depend on data.
2. Data transfer time is not included in the write and erase time.
3. Minimum value that guarantees all characteristics after rewriting (guarantees in the
range from 1 to Min. value).
4. Characteristics when the number of rewrite times falls within the range including the
Min. value.
