DETAILED TEST CONDITIONS FOR DDR SDRAM IDD1 & IDD7
IDD1 : Operating current: One bank operation
1. Typical Case : VDD = 2.5V, T=25 ^oC
2. Worst Case : VDD = 2.7V, T= 0 ^oC
3. Only one bank is accessed with tRC(min), Burst Mode, Address and Control inputs on NOP edge are
changing once per clock cycle. lout = 0mA
4. Timing patterns
- DDR266B(133Mhz, CL=2.5) : tCK = 7.5ns, CL=2.5, BL=4, tRCD = 3*tCK, tRC = 9*tCK, tRAS = 5*tCK
Read : A0 N N R0 N P0 N N N A0 N - repeat the same timing with random address changing
50% of data changing at every burst
- DDR266A (133Mhz, CL=2) : tCK = 7.5ns, CL=2, BL=4, tRCD = 3*tCK, tRC = 9*tCK, tRAS = 5*tCK
Read : A0 N N R0 N P0 N N N A0 N - repeat the same timing with random address changing
50% of data changing at every burst
- DDR333(166Mhz, CL=2.5) : tCK = 6ns, CL=2, BL=4, tRCD = 3*tCK, tRC = 10*tCK, tRAS = 7*tCK
Read : A0 N N R0 N N N P0 N N A0 N - repeat the same timing with random address changing
50% of data changing at every burst
Legend : A=Activate, R=Read, W=Write, P=Precharge, N=NOP
IDD7 : Operating current: Four bank operation
1. Typical Case : VDD = 2.5V, T=25 ^oC
2. Worst Case : VDD = 2.7V, T= 0 ^oC
3. Four banks are being interleaved with tRC(min), Burst Mode, Address and Control inputs on NOP edge are not
changing. lout = 0mA
4. Timing patterns
- DDR266B(133Mhz, CL=2.5) : tCK = 7.5ns, CL=2.5, BL=4, tRRD = 2*tCK, tRCD = 3*tCK Read with autoprecharge
Read : A0 N A1 R0 A2 R1 A3 R2 N R3 A0 N A1 R0 - repeat the same timing with random address changing
50% of data changing at every burst
- DDR266A (133Mhz, CL=2) : tCK = 7.5ns, CL2=2, BL=4, tRRD = 2*tCK, tRCD = 3*tCK
Read : A0 N A1 R0 A2 R1 A3 R2 N R3 A0 N A1 R0 - repeat the same timing with random address changing
50% of data changing at every burst
- DDR333(166Mhz, CL=2.5) : tCK = 6ns, CL=2.5, BL=4, tRRD = 2*tCK, tRCD = 3*tCK, Read with autoprecharge
Read : A0 N A1 R0 A2 R1 A3 R2 N R3 A0 N A1 R0 - repeat the same timing with random address changing
50% of data changing at every burst
Legend : A=Activate, R=Read, W=Write, P=Precharge, N=NOP
