1.2.7 Block Erase, (Page Buffer) Program and Block Lock Configuration 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 (the first edge of CE
5. If the interval time from a Block Erase Resume command to a subsequent Block Erase Suspend command is shorter
6. These values are valid when the page buffer is full, and the start address is aligned on a 16-word/ 32-byte boundary.
7. Program time per byte (t
