Symbol Parameter Test Conditions -6 -75 Units IDD1 Operating Current (Note 1) Burst length=2, tRC≥tRC(min.), IOL=0mA, One bank active 195 180 mA IDD2P Precharge Standby Current in Power Down Mode CKE ≤V IL(max.), tCK=min 15 15 mA IDD2N Precharge Standby Current in Non-power Down Mode (All banks idle) CKE ≥V IH(min.), tCK=min, /CS ≥V IH(min.), VIN=VREF Input signals are changed once per clock cycle 65 60 mA IDD3P Active Standby Current in Power Down Mode CKE ≤V IL(max.), tCK=min One bank active, VIN=VREF 35 30 mA IDD3N Active Standby Current in Non-power Down Mode CKE ≥V IH(min.), tCK=min, /CS ≥V IH(min.) Input signals are changed once per clock cycle 65 65 mA READ 220 200 IDD4 Operating Current (Note 2) tCK ≥ tCK(min.), IOL=0mA, One banks active, BL=2 WRITE 230 210 mA IDD5 Refresh Current (Note 3) tRC≥ tRFC (min.), All banks active 340 330 mA IDD6 Self Refresh Current CKE ≤0.2V 9 9 mA IDD7 Operating current (Four Banks) Four Banks interleaving, BL=4 525 485 mA *All voltages referenced to VSS. Note 1: IDD1 depends on output loading and cycle rates. Specified values are obtained with the output open. Input signals are changed only one time during tCK (min.) Note 2: IDD4 depends on output loading and cycle rates. Specified values are obtained with the output open. Input signals are changed only one time during tCK (min.) Note 3: Min. of tRFC (Auto refresh Row Cycle Times) is shown at AC Characteristics. Recommended DC Operating Conditions (Continued) Symbol Parameter Test Conditions Min. Max.
