DC Characteristics and Operating Conditions (Vdd, VddQ = 2.5V ± 0.15V, Ta = 0~70×°C)
Item
Operating Current
tCK = min, IRC=min
Read/Write command cycling
OV<=VIN<=VIL(AC) (max.) VIH(AC)(min.) <=VIN<=VddQ
1 bank operation, Burst Length = 4
Address change up to 2 times during minimum IRC.
Standby Current
tCK=min, CS = VIH, PD = VIH,
0V<=VIN<=VIL(AC)(max.) VIH(AC)(min.)<=VIH<=VddQ
All Banks : inactive state
Other input signals are changed one time during 4*tCK
Standby (Power Down) Current
tCK=min, CS = VIH, PD = VIL (Power Down)
0V<=VIN<=VddQ
All Banks : inactive state
Auto-Refresh Current
tCK = min, IREFC= min, tREFI = min
Auto-Refresh command cycling
0V<=VIN<=VIL(AC) (max.), VIH(AC) (min.) <=VIN<=VddQ
Address change up to 2 times during minimum IREFC.
Self-Refresh Current

Notes : 1. These parameters depend on the cycle rate and these values are measured at a cycle rate with the minimum values of tCK, tRC and IRC.
2. These parameters depend on the output loading. The specified values are obtained with the output open.
3. Refer to output driver characteristics for the detail. Output Driver Strength is selected by Extended Mode Register.
