Notes 1.
For read cycles, access time is defined as follows:
Input conditions
Access time
Access time from /RAS
t
RAD
≤
t
RAD (MAX.)
and t
RCD
≤
t
RCD (MAX.)
t
RAC (MAX.)
t
RAC (MAX.)
t
RAD
> t
RAD (MAX.)
and t
RCD
≤
t
RCD (MAX.)
t
AA (MAX.)
t
RAD
+ t
AA (MAX.)
t
RCD
> t
RCD (MAX.)
t
CAC (MAX.)
t
RCD
+ t
CAC (MAX.)
t
RAD (MAX.)
and t
RCD (MAX.)
are specified as reference points only; they are not restrictive operating parameters.
They are used to determine which access time (t
RAC
, t
AA
or t
CAC
) is to be used for finding out when output
data will be available. Therefore, the input conditions t
RAD
≥
t
RAD (MAX.)
and t
RCD
≥
t
RCD (MAX.)
will not cause
any operation problems.
2.
Either t
RCH (MIN.)
or t
RRH (MIN.)
should be met in read cycles.
3.
t
OEZ (MAX.)
defines the time when the output achieves the condition of Hi-Z and is not referenced to V
OH
or V
OL
.
4.
/WE : inactive (in read cycle)
/CAS : inactive, /OE : active ...... t
CHO
is effective.
/RAS, /OE : active ...... t
OCH
is effective.
