What is DDR Memory?
Double data rate synchronous dynamic random access memory, or DDR SDRAM for short, is a type of computer memory used in Pentium III or higher computers. DDR RAM is the computer’s primary working memory, storing program instructions and data for use by the central processing unit (CPU) through the bus controller. DDR memory belongs to the dual in-line memory module (DIMM) architectural family and is a faster form of SDRAM. Each module of DDR memory has one notch on the connecting side and two notches on the side that attach to latches on the PC motherboard to hold it in place. DDR RAM can come in either single-sided or double-sided chip configurations. Desktop DDR has 184 pins, as compared to 168 pins on SDRAM. Laptop versions, called SO-DIMMs, contain 200 pins. ...
