Notes
Operating one bank active-precharge current;
tCK = tCK(IDD), tRC = tRC(IDD), tRAS = tRASmin(IDD); CKE is HIGH, CS\ is HIGH between valid commands;
Address bus inputs are SWITCHING; Data bus inputs are SWITCHING
Operating one bank active-read-precharge current;
IOUT = 0mA; BL = 4, CL = CL(IDD), AL = 0; tCK = tCK(IDD), tRC = tRC (IDD), tRAS = tRASmin(IDD), tRCD =
tRCD(IDD); CKE is HIGH, CS\ is HIGH between valid commands; Address businputs are SWITCHING; Data pattern
is same as IDD4W
Precharge power-down current;
All banks idle; tCK = tCK(IDD); CKE is LOW; Other control and address bus inputs are STABLE; Data bus inputs are
FLOATING
Precharge quiet standby current;
All banks idle; tCK = tCK(IDD); CKE is HIGH, CS\ is HIGH; Other control and address bus inputs are STABLE; Data
bus inputs are FLOATING
Precharge standby current;
All banks idle; tCK = tCK(IDD); CKE is HIGH, CS\ is HIGH; Other control and address bus inputs are SWITCHING;
Data bus inputs are SWITCHING
Active power-down current;
Fast PDN Exit MRS(12) = 0mA
All banks open; tCK = tCK(IDD); CKE is LOW; Other control and address bus
Slow PDN Exit MRS(12) = 1mA
inputs are STABLE; Data bus inputs are FLOATING
Active standby current;
All banks open; tCK = tCK(IDD), tRAS = tRASmax(IDD), tRP = tRP(IDD); CKE is HIGH, CS\ is HIGH between valid
commands; Other control and address bus inputs are SWITCHING; Data bus inputs are SWITCHING
Operating burst write current;
All banks open, Continuous burst writes; BL = 4, CL = CL(IDD), AL = 0; tCK = tCK(IDD), tRAS = tRASmax(IDD), tRP
= tRP(IDD); CKE is HIGH, CS\ is HIGH between valid commands; Address bus inputs are SWITCHING; Data bus
inputs are SWITCHING
Operating burst read current;
All banks open, Continuous burst reads, IOUT = 0mA; BL = 4, CL = CL(IDD), AL = 0; tCK = tCK(IDD), tRAS = tRAS-
max(IDD), tRP = tRP(IDD); CKE is HIGH, CS\ is HIGH between valid commands; Address bus inputs are SWITCH-
ING; Data pattern is same as IDD4W
Burst auto refresh current;
tCK = tCK(IDD); Refresh command at every tRFC(IDD) interval; CKE is HIGH, CS\ is HIGH between valid com-
mands; Other control and address bus inputs are SWITCHING; Data bus inputs are SWITCHING
Self refresh current;

Operating bank interleave read current;
All bank interleaving reads, IOUT = 0mA; BL = 4, CL = CL(IDD), AL = tRCD(IDD)-1*tCK(IDD); tCK = tCK(IDD), tRC
= tRC(IDD), tRRD = tRRD(IDD), tFAW = tFAW(IDD), tRCD = 1*tCK(IDD); CKE is HIGH, CS\ is HIGH between valid
commands; Address bus inputs are STABLE during DESELECTs; Data pattern is same as IDD4R; Refer to the fol-
