OPERATING READ CURRENT*) :
All device banks open, Continuous burst reads;
One module rank active; I_OUT = 0mA; BL = 4, CL =
CL (I_DD), AL = 0; t_CK = t_CK (I_DD), t_RAS = t_RAS MAX
(I_DD), t_RP = t_RP (I_DD); CKE is HIGH, CS# is HIGH
between valid commands; Address bus inputs are
changing once every two clock cycles; DQ inputs
changing once per clock cycle
OPERATING WRITE CURRENT*) :
All device banks open, Continuous burst writes;
One module rank active; BL = 4, CL = CL (I_DD), AL
= 0;
t_CK = t_CK (I_DD), t_RAS = t_RAS MAX (I_DD), t_RP = t_RP (I_DD);
CKE is HIGH, CS# is HIGH between valid
commands; Address bus inputs are changing once
every two clock cycles; DQ inputs changing once
per clock cycle
BURST REFRESH CURRENT:
t_CK = t_CK (I_DD); refresh command at every t_RFC (I_DD)
interval, CKE is HIGH, CS# is HIGH between valid
commands; All other Control and Address bus
inputs are changing once every two clock cycles;
DQ inputs changing once per clock cycle
SELF REFRESH CURRENT:
CK and CK# at 0V; CKE ≤ 0.2V; All other Control
and Address bus inputs are floating at V_REF; DQ’s
are floating at V_REF
OPERATING CURRENT*) :
Four device bank interleaving READs, I_OUT = 0mA; BL
= 4, CL = CL (I_DD), AL = t_RCD (I_DD) – 1 x t_CK (I_DD); t_CK
= t_CK (I_DD), t_RC = t_RC (I_DD), t_RRD = t_RRD (I_DD), t_RCD =
t_RCD (I_DD);
CKE is HIGH, CS# is HIGH between valid
commands; Address bus inputs are not changing
during DESELECT; DQ inputs changing once per
clock cycle
