DDR RAM - DDR2 RAM - DDR3 RAM : The New Getting a Newer Look

Computer RAM Manufacturers

DDR SDRAM is a recent addition to the market. But the demand for higher speed and increased efficiency requires additions and everyday inventions in this module. To serve the purpose, the market was first introduced to DDR2 RAM – and now the DDR3 RAM. With revised transfer rate and multiple circuits, DDR3 RAM Serves as a boon to the computer.

While searching for the premium memory modules for computer, everyone wants an interface that has higher and higher transfer rate possible. When it comes to memory integrated circuits used in computers, Single Data Rate Memory (SDRAM) seems to be outdated. The newer version, Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM), certainly has all the advantages. Be it the memory chips or the memory modules, SDRAM has been superseded by DDR SDRAM.

As the name suggests, DDR SDRAM achieves about double bandwidth of the single data rate SDRAM. This particular type of RAM has more strict control of the timing of the electrical data and clock signals. With the maximum transfer rate of about 1600 MB per second, DDR SDRAM has become the preferred choice of all the computer users worldwide.

Expansion

Based on the same principles, computer RAM manufacturers are now coming up with latest types of DDR SDRAM with several added advantages. The first one (DDR1) was superseded by DDR2 SDRAM. Its main specialty was the higher clock frequency.

Once DDR2 became the standard memory module in the market, IT professionals have now come up with DDR3 SDRAM, which is again implemented because of its higher performance and added features.

Till the Decade of 1990s

It was the time, when computer hardware and software industry started its expansion all around the globe. SDRAM was declared a standardized memory module, which was compatible with all kinds of motherboards because of its low frequency. Later, to bring in the concept of higher speed, DDR RAM came in to limelight. Being developed with multiple integrated circuits, it was much faster that the older SDRAM. Running on 2.5 volts per modules, DDR RAM was capable to reduce the power consumption with its multiple circuits.

In terms of better value, DDR3 RAM is definitely the best memory module for your computer. Keeping in mind the overall performance of DDR3 RAM, the experts estimate that this kind of memory will eventually come of age and its prices will also decrease.
