6.2.8 BLOCK ERASE, FULL CHIP ERASE, WORD/BYTE WRITE AND LOCK-BIT
NOTES:
1. Typical values measured at T
2. Excludes system-level overhead.
3. Sampled but not 100% tested.
4. A latency time is required from issuing suspend command(WE# or CE# going high) until RY/BY# going High Z or SR.7
5. If the time between writing the Block Erase Resume command and writing the Block Erase Suspend command is shorter
