NOTES:

*ICC1, ICC3, ICC4 and ICC6 are dependent on output loading and cycle rates. Specified values are obtained with the output open. ICC is specified as an

average current. In ICC1, ICC3, and ICC6 address can be changed maximum once while RAS\ = VIL. In ICC4, address can be changed maximum once within one

fast page mode cycle time, tPC.
