1. ICC1, ICC3, ICC4 and ICC6 depend on cycle rate.
2. ICC1 and ICC4 depend on output loading. Specified values are obtained with the output open.
3. Address can be changed once or less while RAS =VIL. In the case of ICC4, it can be changed once or less when CAS =VIH.
4. Refresh current is specified for 1 bank active and 1 bank standby.
