Proposed Conditions
Operating one bank active-precharge current;
mands; 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; t CK = t CK(IDD), t RC = t RC (IDD), t RAS = t RASmin(IDD), t RCD
= t RCD(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; t CK = t CK(IDD); CKE is LOW; Other control and address bus inputs are STABLE; Data bus
inputs are FLOATING
Precharge quiet standby current;
All banks idle; t CK = t CK(IDD); CKE is HIGH, CS\ is HIGH; Other control and address bus inputsare STA-
BLE; Data bus inputs are FLOATING
Precharge standby current;
All banks idle; t CK = t CK(IDD); CKE is HIGH, CS\ is HIGH; Other control and address bus inputs are
SWITCHING; Data bus inputs are SWITCHING
Active power-down current;
All banks open; t CK = t CK(IDD); CKE is LOW; Other control and
address bus inputs are STABLE; Data bus inputs are FLOATING
Active standby current;
All banks open; t CK = t CK(IDD), t RAS = t RASmax(IDD), t RP = t RP(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; t CK = t CK(IDD), t RAS = t RAS-
max(IDD), t RP = t RP(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; t CK = t CK(IDD), t RAS
= t RASmax(IDD), t RP = t RP(IDD); CKE is HIGH, CS\ is HIGH between valid commands; Address bus
inputs are SWITCHING; Data pattern is same as IDD4W
Burst auto refresh current;
t CK = t CK(IDD); Refresh command at every t RFC(IDD) interval; CKE is HIGH, CS\ is HIGH between valid
commands; Other control and address bus inputs are SWITCHING; Data bus inputs are SWITCHING
Self refresh current;
CK and CK\ at 0V; CKE ≤ 0.2V; Other control and address bus inputs
are FLOATING; Data bus inputs are FLOATING
Operating bank interleave read current;
All bank interleaving reads, IOUT = 0mA; BL = 4, CL = CL(IDD), AL = t RCD(IDD)-1* t CK(IDD); t CK =
t CK(IDD), t RC = t RC(IDD), t RRD = t RRD(IDD), t RCD = 1* t CK(IDD); CKE is HIGH, CS\ is HIGH between
valid commands; Address bus inputs are STABLE during DESELECTs; Data pattern is same as IDD4R;
