1GB – 2x64Mx72 DDR SDRAM REGISTERED, w/PLL  
FEATURES  
DESCRIPTION  
200-pin SO-DIMM, dual in-line memory module  
The WV3EG264M72ESFR is a 2x64Mx72 Double Data  
Rate DDR SDRAM high density module. This memory  
module consists of eighteen 64Mx8 bit with 4 banks DDR  
Synchronous DRAMs in FBGA packages, mounted on a  
200-pin SO-DIMM FR4 substrate.  
Fast data transfer rates: PC2100 and PC2700  
Utilizes 266 and 333 Mb/s DDR SDRAM  
components  
VCC = VCCQ = 2.5V 0.2V  
Bidirectional data strobe (DQS) option  
Differential clock inputs (CK and CK#)  
DLL to align DQ and DQS transitions with CK  
Programmable burst: length (2, 4, 8)

1. Includes 25mV margin for DC offset on VREF, and a combined total of 50mV margin for all AC noise and DC offset on VREF, bandwidth limited to 20MHz. The DRAM must  
accommodate DRAM current spikes on VREF and internal DRAM noise coupled to VREF, both of which may result in VREF noise. VREF should be de-coupled with an inductance of ≤ 3nH.  
2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF, and must track variations in the DC level of VREF  
3. VID is the magnitude of the difference between the input level on CK and the input level on CK#.  
4. These parameters should be tested at the pin on actual components and may be checked at either the pin or the pad in simulation. The AC and DC input specifications are relative  
to a VREF envelop that has been bandwidth limited to 200MHz.
