Notes
4. All AC characteristics are shown on SDRAM component level.
An initial pause of 100
μ
s is required after power-up, then a Precharge All Banks command must
be given followed by eight Auto-Refresh (CBR) cycles before the Mode Register Set Operation
can begin.
5. AC timing tests have
V
IL
= 0.4 V and
V
IH
= 2.4 V with the timing referenced to the 1.4 V crossover
point. The transition time is measured between
V
and
V
. All AC measurements assume
t
= 1 ns with the AC output load circuit show. Specified
t
and
t
parameters are measured
with a 50 pF only, without any resistive termination and with a input signal of 1 V/ns edge rate
between 0.8 V and 2.0 V.
6. If clock rising time is longer than 1 ns, a time (
t
T

–
0.5) ns must be added to this parameter.
7. Rated at 1.4 V
8. If
t
is longer than 1 ns, a time (
t
–
1) ns has to be added to this parameter.
9. Anytime the Refresh Period has been exceeded, a minimum of two Auto-Refresh (CBR)
commands must be given to
“
wake-up
”
the device.
10.Timing is asynchronous. If setup time is not met by rising edge of the clock then the CKE signal
is assumed latched on the next cycle.
