 depend on output loading and cycle rates(t

).
2. Specified values are obtained with output unloaded.
3. I
CC
 is specified as an average current. In I
CC1
, I
CC3
, I
CC6
, address can be changed only once while /RAS=V
IL
. In I
CC4
,
    address can be changed maximum once while /CAS=V
IH
 within one Fast Page mode cycle time t
PC
.
4. Only tRAS(max)
= 1μs is applied to refresh of battery  backup but tRAS(max) = 10μs is to applied to normal functional
    operation.
5. Icc5(max.), Icc7 and Icc8 are applied to L-part only.
6. Operating condition for 50ns part is Vcc=5V
 
 5%,Cout 30pF.
