DDR - 256MB, 512MB, 1GB, 2GB and 4GB

Product Detail

DDR SDRAM was the follow-on technology to SDRAM and is the predecessor to subsequent generations of DDR2 and DDR3. DDR provides a lower voltage level and higher data transfer compared to SDRAM. The voltage level is reduced from 3.30 volts to 2.50 volts and the memory module provides a data transfer on both transitions of the clock signal. This produces more data transfers for a given clock speed, but with the drawback of increased latency. Virtium supports DDR modules in a wide range of configurations and features that are available in 184 and 200 pin DIMM and 200 pin SODIMM form factors.
