Notes: 1. Programming/erasure time is data-dependent.
2. Programming/erasure time does not include data transfer time.
3. Minimum number to guarantee all the characteristics after reprogramming. (Guaranteed
within the range from 1 to min. value)
4. Characteristics when reprogramming is performed within the specified number of times
including min. value.
