b:
I
CC1
and I
CC3
are depedent on output loading and cycle rate. The specified values are obtained with outputs unloaded.
The current I
CC1
is measured for WRITE/READ - ratio of 1/2.
I
CC2
and I
CC4
are the average currents required for the duration of the respective STORE cycles (STORE Cycle Time).
Bringing E

V
IH
will not produce standby current levels until any nonvolatile cycle in progress has timed out. See MODE SELECTION
table. The current I
CC(SB)1
is measured for WRITE/READ - ratio of 1/2.
