DESCRIPTION The WV3EG232M64EFSU is a 2x32Mx64 Double Data Rate SDRAM memory module based on 256Mb DDR SDRAM components. The module consists of sixteen 32Mx8 4 banks DDR SDRAMs in FBGA packages mounted on a 200 pin FR4 substrate. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges and Burst Lengths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.

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. 5. The value of VIX is expected to equal 0.5*VCCQ of the transmitting device and must track variations in the dc level of the same.

Maximum burst refresh cycle : 8 2. The specific requirement is that DQS be valid (High or Low) on or before this CK edge. The case shown (DQS going from High_Z to logic Low) applies when no writes were previously in progress on the bus. If a previous write was in progress, DQS could be High at this time, depending on tDQSS. 3. The maximum limit for this parameter is not a device limit. The device will operate with a great value for this parameter, but system performance (bus turnaround) will degrade accordingly. 4. A write command can be applied with tRCD satisfied after this command. 5. For registered DIMMs, tCL and tCH are ≥ 45% of the period including both the half period jitter (tJIT(HP)) of the PLL and the half period jitter due to crosstalk (tJIT(crosstalk)) on the DIMM. 6.
