are dependent on output loading and cycle rates. Specified values are obtained with the output open.
I
CC
is specified as an average current. In I
CC1
and I
CC3
, address can be changed maximum once while RAS=V
IL
. In I
CC4
,
address can be changed maximum once within one EDO mode cycle time,

.
* NOTE :
ABSOLUTE MAXIMUM RATINGS *
* Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to
the conditions as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for in
periods may affect device reliability.
