Transition times are measured between V
Transition (rise and fall) of input signals have a fixed slope.
If the result of nominal calculation with regard to t

(i.e., t
These parameters are measured from the differential clock (CLK and CLK ) AC cross point.
These parameters are measured from signal transition point of DQS crossing V
In case of DQS enable mode, these parameters are measured from the crossing point of DQS and DQS .
The t
In such case, the average interval of eight consecutive Auto-Refresh commands has to be more than 400 ns
always. In other words, the number of Auto-Refresh cycles which can be performed within 3.2 s (8
is to 8 times in the maximum.
Low Impedance State is specified at V
High Impedance State is specified where output buffer is no longer driven.
These parameters depend on the clock jitter. These parameters are measured at stable clock.
Output timing is measured by using Normal driver strength at V
Output timing is measured by using Strong driver strength at V
