Notes:
1.
Unless noted otherwise, all parameters are measured at TA = +25 °C and nominal voltages, and are sampled, not 100%
tested.
2.
Excludes external system-level overhead.
3.
Exact results might vary based on system overhead.
4.
W400-Typ is the calculated delay for a single programming pulse. W400-Max includes the delay when programming
within a new word-line.
5.
Some EFP performance degradation might occur if block cycling exceeds 10.
