IDD1 : OPERATING CURRENT: ONE BANK
1. Typical Case: VCC = 2.5V, T = 25°C
2. Worst Case: VCC = 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
DDR200 (100MHz, CL = 2) : tCK = 10ns, CL2, BL =
4, tRCD = 2*tCK, tRAg = 5*tCK
Read: A0 N R0 N N P0 N A0 N - repeat the same
timing with random address changing; 50% of data
changing at every burst
DDR266 (133MHz, CL = 2.5) : tCK = 7.5ns, CL =
2.5, BL = 4, tRCD = 3*tCK, tRC = 9*tCK, tRAg = 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
DDR266 (133MHz, CL = 2) : tCK = 7.5ns, CL = 2, BL
= 4, tRCD = 3*tCK, tRC = 9*tCK, tRAg = 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, BL = 4,
tRCD = 10*tCK, tRAg = 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
IDD7A: OPERATING CURRENT: FOUR BANKS
1. Typical Case: VCC = 2.5V, T = 25°C
2. Worst Case: VCC = 2.7V, T = 10°C
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
DDR200 (100MHz, CL = 2) : tCK = 10ns, CL2,
BL = 4, tRRD = 2*tCK, tRCD = 3*tCK, Read with
autoprecharge
Read: A0 N A1 R0 A2 R1 A3 R2 A0 R3 A1 R0
- repeat the same timing with random address
changing; 100% of data changing at every burst
DDR266 (133MHz, CL = 2.5) : tCK = 7.5ns, CL =
2.5, BL = 4, tRRD = 3*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; 100% of data changing at every burst
DDR266 (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; 100% of data changing at every burst
DDR333 (166MHz, CL = 2.5) : tCK = 6ns, BL = 4,
tRRD = 3*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; 100% of data changing at every burst
Legend: A = Activate, R = Read, W = Write, P =
DETAILED TEST CONDITIONS FOR DDR SDRAM IDD1 & IDD7A
Precharge, N = NOP
A (0-3) = Activate Bank 0-3
R (0-3) = Read Bank 0-3
