| DRAM DDR2 |
DDR2 has been the standard memory solution for applications in virtually all market segments from Servers, PCs and Notebooks to Printers, Networking and Storage systems and many more for several years providing superior cost and performance criteria. DDR2 has relinquished its role as the memory industry's mainstream technology to DDR3 and is now considered a legacy product. Available in power supply voltages of 1.8V (and 1.55V for FBDIMMs) and with data rates from 400 to 800 Mega-Transfers per Second, DDR2 has been designed for a wide range of applications providing designers with numerous module options to choose from. |
