- DDR2 was introduced in 2003 and operates twice as fast as DDR due to an improved bus signal. DDR2 uses the same internal clock speed as DDR, however, the transfer rates are faster due to the enhanced input/output bus signal. DDR2 has a 4-bit prefetch, which is twice that of DDR.www.crucial.com/articles/about-memory/difference-among-ddr2-ddr3-ddr4-and-…

DDR2 SDRAM - Wikipedia
GDDR2, a form of GDDR SDRAM, was developed by Samsung and introduced in July 2002. The first commercial product to claim using the "DDR2" technology was the Nvidia GeForce FX 5800 graphics card. However, this GDDR2 memory used on graphics cards is not DDR2 per se, but rather an early midpoint between DDR and DDR2 technologies. Using "DDR2" to refer to GDDR2 is a colloquial misnomer. In particular, the performance-enhancing doubling of the I/O clock rate i…
Wikipedia · Text under CC-BY-SA licenseWhat's the Difference Between DDR2, DDR3, and DDR4 RAM?
- If you're new to RAM, you might not know what "DDR" means. This abbreviation stands for double data rate. In simple terms, operating at a double data rate means the RAM can transfer data two times per clock cycle. As you probably know, all data on a computer is digital, meaning it's represented by a 1 (on) or a 0 (off). One clock cycle is represent...
