Worst case : VDD = 2.7V, T = 10’C
Conditions
Operating current - One bank Active-Precharge;
tRC=tRCmin;tCK=100Mhz for DDR200, 133Mhz for DDR266A & DDR266B;
DQ,DM and DQS inputs changing twice per clock cycle;
address and control inputs changing once per clock cycle
Operating current - One bank operation ; 
One bank open, BL=4, Reads 
- Refer to the following page for detailed test condition 
Percharge power-down standby current; 
All banks idle; power - down mode;
CKE = <VIL(max); tCK=100Mhz for DDR200, 133Mhz for DDR266A & DDR266B;
Vin = Vref for DQ,DQS and DM
Precharge Floating standby current; 
CS# > =VIH(min);All banks idle;
CKE > = VIH(min);  tCK=100Mhz for DDR200, 133Mhz for DDR266A & DDR266B;
Address and other control inputs changing once per clock cycle;
Vin = Vref for DQ,DQS and DM
Precharge Quiet standby current; 
CS# > = VIH(min); All banks idle;
CKE > = VIH(min);   tCK = 100Mhz for DDR200, 133Mhz for DDR266A & DDR266B;
Address and other control inputs stable with keeping >= VIH(min) or =<VIL(max);
 Vin = Vref for DQ ,DQS and DM
Active power - down standby current ; 
one bank active;  power-down mode; 
CKE=< VIL (max); tCK = 100Mhz for DDR200, 133Mhz for DDR266A & DDR266B;
Vin = Vref for DQ,DQS and DM
Active standby current; 
CS# >= VIH(min); CKE>=VIH(min);
one bank active; active - precharge; tRC=tRASmax; tCK = 100Mhz for DDR200,
133Mhz for DDR266A & DDR266B; DQ, DQS and DM inputs changing twice
per clock cycle; address and other control inputs changing once
per clock cycle
Operating current - burst read; 
Burst length = 2; reads; continguous burst;
One bank active; address and control inputs changing once per clock cycle; 
CL=2 at tCK = 100Mhz for DDR200, CL=2 at tCK = 133Mhz for DDR266A,  CL=2.5 at tCK = 
133Mhz for DDR266B ; 50% of data changing at every burst;  lout = 0 m A
Operating current - burst write; 
Burst length = 2; writes; continuous burst;
One bank active address and control inputs changing once per clock cycle;
 CL=2 at tCK = 100Mhz for DDR200, CL=2 at tCK = 133Mhz for DDR266A,
CL=2.5 at tCK = 133Mhz for DDR266B ; DQ, DM and DQS inputs changing twice
per clock cycle, 50% of input data changing at every burst
Auto refresh current; 
tRC = tRFC(min) - 8*tCK for DDR200 at 100Mhz, 
10*tCK for DDR266A & DDR266B at 133Mhz; distributed refresh
Self refresh current; 
CKE =< 0.2V;  External clock should be on;
