DDR Memory (Double Data Rate Memory) is an evolutionary product built upon the foundation of older PC100/PC133 memory technology. Unlike SDRAM memory that supports one operation per the computer's clock cycle, DDR SDRAM memory can do two operations per clock cycle, thereby doubling the memory bandwidth over the corresponding single data rate SDRAM.
Kingston Technology Company is an active member of JEDEC, the computer industry's standards body which developed and finalized the specifications for the DDR SDRAM modules. Kingston's Director of Technology sits on the Board of Directors of JEDEC, elected to a position title of Vice Chairman at Large. Kingston's engineers actively participate in the memory technology subcommittees working on current and next generation memory products.
Kingston's DDR Memory payment efforts closely involve leading semiconductor, processor, chipset and motherboard manufacturers as well as PC OEMs.
DDR The Mainstream Memory Technology Through mid 2005:
DDR Memory was selected by the computer industry to be the mainstream memory technology to replace SDRAM memory. By 2005, it was used in many different platforms, including desktop PCs, servers, notebooks, compact and sub-compact computers, and networking/communications platforms.
DDR memory was selected because of its increased performance as well as its low cost premium over SDRAM, since DDR can easily be manufactured by existing semiconductor fabrication plants and can be built and tested without significant capital investments. DDR Memory delivers increased memory bandwidth and performance over SDRAM memory for many business, ultimedia, and entertainment applications.
Kingston has a comprehensive line of DDR modules for desktop PCs, servers, notebooks,compact and sub-compact computers and networking/communications applications.
* ECC or non-ECC modules.
* Unbuffered DDR DIMMs.
* Registered DDR DIMMs for servers and high end workstations.
* High capacity stacked Registered DDR DIMMs for servers and workstations.
* Unbuffered DDR SO DIMMs for portable PCs or communications/networking applications.
* Unbuffered Micro DIMMs for portable, compact and subcompact PCs, and
communications/networking applications.
* Custom DDR modules for special networking, communications or custom applications.
