Notes: 8. Minimum number of times for which all
characteristics are guaranteed after rewriting (Guarantee range
is 1 to minimum value).
9. Reference value for 25°C (as a guideline, rewriting should
normally function up to this value).
10. Data retention characteristic when rewriting is performed
within the specification range, including the minimum value.
