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