Double Data Rate 2 Synchronous Dynamic Random Access Memory(DDR2-SDRAM), also known as DDR-2, is the improved version of DDR-SDRAM. DDR2-SDRAM offers greater bandwidth and density in a smaller package along with a reduction in power consumption. In addition DDR2-SDRAM offers new features and functions that enable higher a clock rate and data rate operations. DDR2 transfers 64 bits of data twice every clock cycle. DDR2-SDRAM memory is not compatible with current DDR-SDRAM memory slots.
