DDR SDRAM utilizes the existing SDRAM infrastructure and technology while doubling the nominal bandwidth available to systems.
To put it in a simple way, DDR SDRAM is like data going along a two lane highway, while at the same time data in traditional
SDRAM go along a one way street. Therefore, it is a more advanced technology that provides a great overall improvement in
system performance. DDR266 (PC2100) runs two times faster than the traditional PC133 SDRAM with the speed of Front Side Bus
(FSB) up to 266MHz. (2x133=266). And DDR333 (PC2700) is running at 333MHz FSB.
naming standard for speed of DDR 266 and DDR 333, representing their theoretical speeds of the RAM.
rate of DDR 266 (PC2100) is 2.1GB/s and 2.7GB/s is for DDR 333 (PC2700).
