1. ICC1, ICC3, ICC4 and ICC6 depend on output loading and cycle rates(tRC and tPC).
2. Specified values are obtained with output unloaded.
3. ICC is specified as an average current. In ICC1, ICC3, ICC6, address can be changed only once while /RAS=VIL. In ICC4,
address can be changed maximum once while /CAS=VIH within one cycle time tPC.
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 SL-part only.
