I_DD0
DQ, DM, and DQS inputs changing once per clock cycle; address and control inputs changing once
every two clock cycles.

I_DD1
Refer to the following page for detailed test conditions.
Precharge Power-Down Standby Current: all banks idle; power-down mode; CKE ≤ V_ILMAX; t_CK =
t_CKMIN
Precharge Floating Standby Current: CS ≥ V_IHMIN, all banks idle;
CKE ≥ V_IHMIN; t_CK = t_CKMIN, address and other control inputs changing once per clock cycle, V_IN = V_REF
for DQ, DQS and DM.
I_DD2P
I_DD2F
Precharge Quiet Standby Current:
CS ≥ V_IHMIN, all banks idle; CKE ≥ V_IHMIN; t_CK = t_CKMIN, address and other control inputs stable
at ≥ V_IHMIN or ≤ V_ILMAX; V_IN = V_REF for DQ, DQS and DM.
Active Power-Down Standby Current: one bank active; power-down mode;
CKE ≤ V_ILMAX; t_CK = t_CKMIN; V_IN = V_REF for DQ, DQS and DM.
Active Standby Current: one bank active; CS ≥ V_IHMIN; CKE ≥ V_IHMIN; t_RC = t_RASMAX; t_CK = t_CKMIN; DQ,
DM and DQS inputs changing twice per clock cycle; address and control inputs changing once per clock
cycle.
