Notes:  
1.  
I
is dependent on output loading when the device output is selected. Specified I (max.) is measured with the

2.  
I
is dependent upon the number of address transitions. Specified I (max.) is measured with a maximum of two  
CC

transitions per address cycle in Fast Page Mode.  
3. Specified V (min.) is steady state operating. During transitions, V (min.) may undershoot to Ò1.0 V for a period

16. Assumes a three-state test load (5 pF and a 380 Ohm Thevenin equivalent).  
17. An initial 200 µs pause and 8 RAS-containing cycles are required when exiting an extended period of bias without  
clocks. An extended period of time without clocks is defined as one that exceeds the specified Refresh Interval.
