Notes:
1) All voltages are referenced to
V
SS
.
2)
I
CC1
,
I
CC3
,
I
CC4
and
I
CC6
depend on cycle rate.
3)
I
CC1
and
I
CC4
depend on output loading. Specified values are obtained with the output open.
4) Address can be changed once or less while RAS =
V
il
. In case of
I
CC4
it can be changed once or less during
a hyper page mode (EDO) cycle
5) An initial pause of 200
μ
s is required after power-up followed by 8 RAS cycles of which at least one cycle has
to be a refresh cycle, before proper device operation is achieved. In case of using the internal refresh counter,
a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required.
6) AC measurements assume
t
T
= 2 ns.
7)
V
I
H
(min.)
and
V
I
L (max.)
are reference levels for measuring timing of input signals. Transition times are also
measured between
V
I
H
and
V
I
L
.
8) Measured with the specified current load and 100 pF at
V
ol
= 0.8 V and
V
oh
= 2.0 V. Access time is determined
by the latter of
t
RAC
,
t
CAC
,
t
AA
,
t
CPA
,
t
OEA
.
t
CAC
is measured from tristate.
9) Operation within the
t
RCD (max.)
limit ensures 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 by
t
CAC
.
10) Operation within the
t
RAD (max.
)
limit ensures that
t
RAC (max.)
can be met.
t
RAD (max.)
is specified as a reference point
only. If
t
RAD
is greater than the specified
t
RAD (max.)
limit, then access time is controlled by
t
AA
.
11) Either
t
RCH
or
t
RRH
must be satisfied for a read cycle.
12)
t
OFF (max.)
,
t
OEZ (max.)
define the time at which the output achieves the open-circuit conditions and are not
referenced to output voltage levels.
t
OFF
is referenced from the rising edge of RAS or CAS, whichever occurs
last.
13) Either
t
DZC
or
t
DZO
must be satisfied.
14) Either
t
CDD
or
t
ODD
must be satisfied.
15)
t
,
t
,
t
and
t
are not restrictive operating parameters. They are included in the data sheet as
electrical characteristics only. If
t
WCS
>
t
WCS (min.)
, the cycle is an early write cycle and data out pin will remain
open-circuit (high impedance) through the entire cycle; if
t
RWD
>
t
RWD (min.)
,
t
CWD
>
t
CWD (min.)
and
t
AWD
>
t
AWD (min.)
,
the cycle is a read-write cycle and I/O will contain data read from the selected cells. If neither of the above
sets of conditions is satisfied, the condition of I/O (at access time) is indeterminate.
16) These parameters are referenced to the CAS leading edge in early write cycles and to the WE leading edge
in read-write cycles.
