DDR Ram

DDR RAM, which stands for Double Data Rate Random Access Memory, is a volatile memory incorporated into computers and some other electronic devices. This memory is classified under the synchronous dynamic random access memory (SDRAM). The DDR RAM makes for double the data transfer rate as compared to non-DDR RAM chips. It achieves this task by allowing data transfer on both the rise and the fall of the clock signal.

There are four basic speeds offered by DDR RAM chips. DDR200 offers a peak data transfer rate of 1.6 GB/second, DDR-266 offers around 2.13 GB/second, DDR-333 has a speed of 2.66 GB/second and DDR-400 permits a transfer speed of 3.2 GB/second. When using DDR RAM, the speed of data transfer is enhanced without the frequency of the front side bus (FSB) also getting inflated.

The smooth functioning of a computer is strongly dependent on the RAM as memory resources are used by both the operating system, as well as all the open applications. DRR RAM comes in different memory levels ranging from 256 MB to 512 MB to 1 GB or 2 GB. The speed of the computer as well as the number of applications that can be opened depends on the amount of DDR RAM present.
