Overview - What is DDR Memory?

DDR is the acronym for Double Data Rate Synchronous DRAM (SDRAM). DDR SDRAM memory technology is an evolutionary technology derived from mature SDRAM technology. The secret to DDR memory's high performance is its ability to perform two data operations in one clock cycle - providing twice the throughput of SDRAM.

DDR SDRAM memory technology has evolved from mainstream PC100 and PC133. This new memory technology enables a new generation of higher performance computer systems, including desktops, workstations, servers, portables, as well as new communications products such as routers and switches. DDR mem

ory technology is currently widely used in high-performance graphic adapters.

DDR DIMMs have the same physical dimensions as SDRAM DIMMs, but have a different footprint that uses 184 pins compared to 168-pin SDRAM DIMMs. Therefore, DDR memory technology is not backward-compatible with SDRAM and requires motherboards and systems especially designed for DDR.

DDR - PC200 184 Pin DIMM	Single Notched (or Keyed)	Two operations per hertz
VS
SDRAM - PC100 168 Pin DIMM	Double Notched (or Keyed)	One operation per hertz

DDR DIMMs will initially support memory bus speeds of either 100 or 133MHz, with faster memory bus speeds under review by JEDEC. Since DDR technology can perform two data operations per clock cycle (versus SDRAM's single operation per clock cycle), the effective data throughput of a DDR DIMM is doubled over an SDRAM DIMM. For example, a 200MHz DDR DIMM will support a 100MHz memory bus and a 266MHz DDR DIMM will support up to a 133MHz memory bus.
