DDR SDRAM IDD SPEC TABLE
* Module IDD was calculated on the basis of component IDD and can be differently measured according to DQ loading cap.
Detailed test conditions for DDR SDRAM IDD1 & IDD
IDD1 : Operating current: One bank operation
1. Typical Case : Vdd = 2.5V, T=25’ C
2. Worst Case : Vdd = 2.7V, T= 10’ C
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
- DDR333 (166MHz, CL=2.5) : tCK=6ns, CL=2.5, BL=4, tRCD=3*tCK, tRC=10*tCK, tRAS=7*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
- DDR400B (200MHz, CL=3) : tCK=5ns, CL=3, BL=4, tRCD=3*tCK, tRC=12*tCK, tRAS=8*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
- DDR400A (200MHz, CL=2.5) : tCK=5ns, CL=2.5, BL=4, tRCD=3*tCK, tRC=12*tCK, tRAS=8*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
Legend : A=Activate, R=Read, W=Write, P=Precharge, N=NOP
