C. Assumes corresponding lock bits

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
0
, CE
1
or CE
2
that disables
the device or the rising edge of WE#) until SR.7 going "1" or STS going High Z.
5. If the interval time from a Block Erase Resume command to a subsequent Block Erase Suspend command is shorter
than t
ERES
and its sequence is repeated, the block erase operation may not be finished.
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
WHQV1
/ t
EHQV1
) is 12.5
μ
s/byte (typical).
Program time per word (t
WHQV2
/ t
EHQV2
) is 25.0
