PARAMETER/CONDITION
OPERATING CURRENT: One device bank; Active-Precharge; ^tRC = ^tRC (MIN);
t_{CK =} t_{CK (MIN); DQ, DM and DQS inputs changing once per clock cyle;}
Address and control inputs changing once every two clock cycles
OPERATING CURRENT: One device bank; Active -Read Precharge; Burst = 4;
t_{RC =} t_{RC (MIN);} t_{CK =} t_{CK (MIN); IOUT = 0mA; Address and control inputs}
changing once per clock cycle
PRECHARGE POWER-DOWN STANDBY CURRENT: All device banks idle;
Power-down mode; ^tCK = ^tCK (MIN); CKE = (LOW)
IDLE STANDBY CURRENT: CS# = HIGH; All device banks idle; ^tCK = ^tCK MIN;
CKE = HIGH; Address and other control inputs changing once per clock cycle.
VIN = VREF for DQ, DQS, and DM
ACTIVE POWER-DOWN STANDBY CURRENT: One device bank active; Power-
down mode; ^tCK = ^tCK (MIN); CKE = LOW
ACTIVE STANDBY CURRENT: CS# = HIGH; CKE = HIGH; One device bank;
Active-Precharge; ^tRC = ^tRAS (MAX); ^tCK = ^tCK (MIN); DQ, DM and DQS
inputs changing twice per clock cycle; Address and other control inputs
changing once per clock cycle
OPERATING CURRENT: Burst = 2; Reads; Continuous burst; One bank active;
Address and control inputs changing once per clock cycle; ^tCK = ^tCK (MIN);
IOUT = 0mA
OPERATING CURRENT: Burst = 2; Writes; Continuous burst; One device bank
active; Address and control inputs changing once per clock cycle; ^tCK = ^tCK
(MIN); DQ, DM, and DQS inputs changing twice per clock cycle
AUTO REFRESH CURRENT
t_{REFC =} t_{RFC (MIN)}
t_{REFC = 7.8125µs}
SELF REFRESH CURRENT: CKE ≤ 0.2V
OPERATING CURRENT: Four device bank interleaving READs (BL = 4) with
auto precharge, ^tRC = ^tRC (MIN); ^tCK = ^tCK (MIN); Address and control inputs
change only during Active READ, or WRITE commands
