I DD5 Auto-Refresh Current :
t RC = t RFC (MIN)
t RC = 7.8 µs
I DD6
I DD7
Self-Refresh Current : CKE ≤ 0.2V
Operating Current: four bank; four bank interleaving with BL = 4, address
and control inputs randomly changing; 50% of data changing at every
transfer; tRC = tRC (min); IOUT = 0mA.
1. I DD specifications are tested after the device is properly initialized.
2. Input slew rate = 1V/ ns.
3. Enables on-chip refresh and address counters.
4. Current at 7.8 µs is time averaged value of IDD5 at tRFC (MIN) and IDD2P over 7.8 µs.
