NOTES (READ CYCLE)
1.
t
HZ
and
t
OHZ
are defined as the time at which the outputs achieve the open circuit conditions and are not referenced to output voltage
levels.
2. At any given temperature and voltage condition,
t
HZ
(Max.) is less than
t
LZ
(Min.) both for a given device and from device to device
interconnection.
3. If invalid address signals shorter than min. t
RC
are continuously repeated for over 4us, the device needs a normal read timing(t
RC
) or
needs to sustain standby state for min. t
RC
at least once in every 4us.

NOTES
(WRITE CYCLE)
1. A wri
t
e occurs during the overlap(t
WP
) of low CS
1
and low WE. A write begins when CS
1
goes low and WE goes low with asserting
UB or LB for single byte operation or simultaneously asserting UB and LB for double byte operation. A write ends at the earliest tran-
sition when CS
1
goes high and WE goes high. The
t
WP
is measured from the beginning of write to the end of write.
2.
t
CW
is measured from the CS
1
going low to the end of write.
3. t
AS
is measured from the address valid to the beginning of write.
4.
t
WR
is measured from the end of write to the address change.
t
WR
is applied in case a write ends with CS
1
or WE going high.
