8 / 14 page 200pin DDR SDRAM SODIMM M470L1714BT0 Rev. 0.1 June. 2001 I DD7A : Operating current: Four bank operation 1. Typical Case : Vdd = 2.5V, T=25’C 2. Worst Case : Vdd = 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 - 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 *100% 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 *100% of data changing at every burst Legend : A=Activate, R=Read, W=Write, P=Precharge, N=NOP AC Operating Conditions Parameter/Condition Symbol Min Max Unit Note Input High (Logic 1) Voltage, DQ, DQS and DM signals VIH(AC) VREF + 0.31 V 3 Input Low (Logic 0) Voltage, DQ, DQS and DM signals. VIL(AC) VREF - 0.31 V 3 Input Differential Voltage, CK and CK inputs VID(AC) 0.7 VDDQ+0.6 V 1 Input Crossing Point Voltage, CK and CK inputs VIX(AC) 0.5*VDDQ-0.2 0.5*VDDQ+0.2 V 2 Note 1. VID is the magnitude of the difference between the input level on CK and the input on CK. 2. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the DC level of the same. 3. These parameters should be tested at the pim on actual components and may be checked at either the pin or the pad in simula- tion. the AC and DC input specificatims are refation to a Vref envelope that has been bandwidth limited 20MHz. |
