Parameter/Condition
Operating one bank active-precharge current:
DQ 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;
t
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
DQS
Active power-down standby current: One device bank active; Power-down mode;
t
Active standby current: CS# = HIGH; CKE = HIGH; One device bank active;
t
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;
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
