NOTES
An initial pause of 200us is required after power-up followed
by any 8 RAS-only or CAS-before-RAS refresh cycles before
proper device operation is achieved.
Input voltage levels are V
ih
/V
il
. V
IH
(min) and V
IL
(max) are ref-
erence levels for measuring timing of input signals. Transition
times are measured between V
IH
(min) and V
IL
(max) and are
assumed to be 5ns for all inputs.
Measured with a load equivalent to 2 TTL loads and 100pF.
Operation within the
t
RCD
(max) limit insures that
t
RAC
(max)
can be met.
t
RCD
(max) is specified as a reference point only.
If
t
RCD
is greater than the specified
t
RCD
(max) limit, then
access time is controlled exclusively by
t
CAC
.
Assumes that
t
RCD
≥
t
RCD
(max).
This parameter defines the time at which the output achieves
the open circuit condition and is not referenced to V
OH
or
V
OL
.
t
WCS
is non-restrictive operating parameter. It is included in
the data sheet as electrical characteristics only. If
t
WCS
≥
t
WCS
(min), the cycle is an early write cycle and the
data out pin will remain high impedance for the duration of
the cycle.
Either
t
RCH
or
t
RRH
must be satisfied for a read cycle.
These parameters are referenced to the CAS leading edge in
early write cycles.
Operation within the
t
RAD
(max) limit insures that
t
RAC
(max)
can be met.
t
RAD
(max) is specified as reference point only. If
t
RAD
is greater than the specified
t
RAD
(max) limit, then
access time is controlled by
t
AA
.
