DDR Dimm Desktop Ram DDR2 Computer Memory DDR3 PC Memory Module

DDR Ram is a class of memory integrated circuits used in computers. It achieves nearly twice the bandwidth of the preceding single data rate SDRAM through double pumping, in transferring data on the rising and falling edges of the clock signal, without increasing clock frequency. There have been three generations of DDR memory so far, namely DDR, DDR2 and DDR3, among which DDR3 Ram has the fastest speed. In general, newer version of PC mainboards use the newer generation of DDR memory chips. Three generations of DDR memory are not compatible to each other. DDR2 DIMM uses double data rate synchronous dynamic random access memory technology, which supersedes the original DDR DIMM specifications. Primary improvement that DDR2 Ram brings over its predecessor is the operation of the external data bus at twice the clock rate. DDR3 desktop memory is an improvement over its predecessor, DDR2 SDRAM. The primary benefit of DDR3 is the ability to transfer at twice the data rate of DDR2, thus enabling higher bus rates and higher peak rates than earlier memory technologies. In addition, the DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes.
