DDR2 SDRAM or double-data-rate two synchronous dynamic random access memory is a computer memory technology. It is a refinement to the existing DRAM technology. JEDEC (Joint Electron Device Engineering Council) which provides standards for memory technologies has standardized this technology.

Double Data Rate and Dual channel Architecture enhances memory performance. DDR2 requires less space and provides high density modules .Power consumption is also less which makes DDR2 a favorite user choice.



DDR2 increases bandwidth, provides reliability, has good signal integrity. DDR2 achieves these by using some prominent technologies. They are On Die Termination, Off Chip Driver Calibration, Posted CAS and Additive Latency, etc. DDR2 memory is supported by all motherboard manufactures.

DDR2 SDRAM or double-data-rate two synchronous dynamic random access memory is a computer memory technology. It is a part of the SDRAM family of random access memory technologies, which is one of many DRAM implementations.
