DDR2 SDRAM , DDR2 Ram

DDR2 SDRAMFrom Wikipedia, the free encyclopedia In information technologies we use the term DDR2 SDRAM for a Double Data Rate memory module of the second generation. Thistechnology is used for high speed storage of the working data. ComparisonsThe main difference between DDR and DDR2 modules is that the bus on which the DDR2 memory modules are working is clocked at twice the speed of the memory cells. In practical terms we can say that four words of data can be transferred during one memory cell cycle. To sum it up DDR2 can effectively operate at twice...
