1.2.7 Block Erase, Full Chip Erase, (Page Buffer) Program and OTP Program Performance
NOTES:
1. Typical values measured at V
2. Excludes external system-level overhead.
3. Sampled, but not 100% tested.
4. A latency time is required from writing suspend command (WE# or CE# going high) until SR.7 going "1".
5. If the interval time from a Block Erase Resume command to a subsequent Block Erase Suspend command is shorter
