Parameter/Condition
Operating one bank active-precharge current:
DQ, DM, and DQS inputs changing once per clock cycle; Address and control inputs
changing once every two clock cycles
Operating one bank active-read-precharge current: BL = 2;

Precharge power-down standby current: All device banks idle; Power-down mode;
t
Idle standby current: CS# = HIGH; All device banks idle;
Address and other control inputs changing once per clock cycle; V

Active power-down standby current: One device bank active; Power-down mode;
t
Active standby current: CS# = HIGH; CKE = HIGH; One device bank; Active-

per clock cycle; Address and other control inputs changing once per clock cycle
Operating burst read current: BL = 2; Continuous burst reads; One device bank
active; Address and control inputs changing once per clock cycle;
I
Operating burst write current: BL = 2; Continuous burst writes; One device bank
active; Address and control inputs changing once per clock cycle;
DM, and DQS inputs changing twice per clock cycle
Auto refresh current
Self refresh current: CKE ≤ 0.2V
Operating bank interleave read current: Four device bank interleaving reads;
BL = 4 with auto precharge;
inputs change only during active READ or WRITE commands
