4.3.4 Data retention vs program/erase cycles

Graphically, Data Retention versus Program/Erase Cycles can be represented by the

following figure. The spec window represents qualified limits. The extrapolated dotted

line demonstrates technology capability, however is beyond the qualification limits.
