Revision (See Manual for Details)
Table 28.15 amended
Notes 8 to 10 added
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.
