NOTES:
1. A write occurs during the overlap of a LOW S-CE
1
, a HIGH S-CE
2
and a LOW S-WE.
A write begins at the latest transition among S-CE
1
going LOW, S-CE
2
going HIGH
and
S-WE going LOW. A write ends at the earliest transition among S-CE
1
going HIGH,
S-CE
2
going LOW and S-WE going HIGH. t
WP
is measured from the beginning of
write to the end of write.
2. t
CW
is measured from the later of S-CE
1
going LOW or S-CE
2
going HIGH to the end
of write.
3. t
BW
is measured from the time of going LOW S-UB or LOW S-LB to the end of write.
4. t
AS
is measured from the address valid to the beginning of write.
5. t
WR
is measured from the end of write to the address change.
6. During this period, DQ pins are in the output state, therefore the input signals of
opposite phase to the outputs must not be applied.
7. If S-CE
1
goes LOW or S-CE
2
goes HIGH simultaneously with S-WE going LOW or
after S-WE going LOW, the outputs remain in HIGH impedance state.
8. If S-CE
1
goes HIGH or S-CE
2
goes LOW simultaneously with S-WE going HIGH or
S-WE going HIGH, the outputs remain in HIGH impedance state.
