Parameter
Operating Current: one bank; active/ precharge;
DQ, DM, and DQS inputs changing once per clock cycle; address and control inputs changing once every two
clock cycles.
Operating Current: one bank; active/read/precharge; Burst = 4;
Refer to the following page for detailed test conditions.
Precharge Power-Down Standby Current: all banks idle; power-down mode; CKE ≤ V
Precharge Floating Standby Current: CS ≥ V
CKE ≥ V
and DM.
Precharge Quiet Standby Current:CS ≥ V
control inputs stable at ≥ V
Active Power-Down Standby Current: one bank active; power-down mode;
CKE ≤ V
Active Standby Current: one bank active; CS ≥ V
inputs changing twice per clock cycle; address and control inputs changing once per clock cycle.
