b: I_CC1 and I_CC3 are dependent 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.
c: I_CC2 is the average current required for the duration of the STORE cycle (STORE Cycle Time).
d: 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.
