• DDR Is Used In High Performance Graphics AdaptersTechnology - Graphics Card image by Rob Hill from Fotolia.com
  
  DDR memory technology is an evolutionary process. Mature PC100 and PC133 SDRAM technology has been extended into SDRAM. DDR memory chips are produced by semiconductor manufacturers using existing wafer fabrication processes which provides an additional benefit of lower memory chip costs.
  
  New memory technology provides each new generation of high performance computer systems, including desktop, workstation, blade-servers, laptop notebooks, portables, routers and switches, with increased performance and reliability factors. DDR memory technology is used in high-performance graphic adapters.
  
  The definition of DDR is 'double data rate', and for SDRAM is 'synchronous dynamic random access memory'.

Double Data Rate

• Typical SDR RAM Memory Configuration For Comparision To DDR SDRAMmemory image by Zbigniew Nowak from Fotolia.com
  
  The name "double data rate" indicates that a DDR SDRAM with a given clock frequency achieves almost twice the bandwidth of a single data rate given as SDR, SDRAM running at the same clock frequency, provided by this 'double-pumping' methodology.
  
  

JEDEC Specification PC2700 and Memory Speed 333.0 MHz

• Typical configuration for 200-pin PC2700 333.0 MHz DDR SDRAM Memorymemory image by glgec from Fotolia.com
  
  JEDEC http://http://www.jedec.org/ developed the DDR (Double Data Rate) SDRAM specification (JESD79).
  
  333.0 MHz is the frequency of the data passing into and out of the DDR SDRAM chip when in use. This module uses the latest high density chips which draw less power and run cooler than other brands. This maintains reliability and an expected long memory life.
  
  PC2700 is the technology name associated with 330.0 MHz DDR SDRAM Memory.
