power up
Device initialization should be performed after a power up to the full V
CC
level. After power is established, a
200-
μ
s interval is required (with no inputs other than CLK). After this interval, all banks of the device must be
deactivated. Eight REFR commands must be performed, and the mode register must be set to complete the
device initialization. See Figure 24.
