Double Data Rate Two (DDR-2), also known as Double Data Rate Two Synchronous Dynamic Random Access Memory(DDR2 SDRAM), is a computer memory technology that, as of 2005, is becoming the mainstream standard for personal computer memory. DDR2 is part of the SDRAM family of random access memory technologies, which is itself one of many DRAM implementations. The advantage of DDR-2 over DDR SDRAM is its ability to run at much higher clock speeds due to an improved electrical interface.
