DDR

DDR is a common term for Double Data Rate. This is a type of memory that has been used in different applications, but more frequently in the video card market. DDR as referred to here is a type of SDRAM that supports data transfers on both edges of each clock cycle, effectively doubling the memory chip's data throughput. The first chipsets that will be supporting the DDR memory technology appeared in graphics subsystem early in 1999, and system core logic chipsets will be coming in early 2001.
