DDR3 SDRAM and its advantages over previous versions

DDR in DDR3 stands for Double Data Rate. It is the latest memory standard for hispeed SDRAM that we use in our computers. DDR3 is a improved version of DDR2 in many aspects. DDR3 Ram is a type of DRAM. DDR3 shows a lesser power consumption of 30 percent and also a lower operating voltage when compared to DDR2.

Lesser power consumption means less amount of heat generated. So, the cooling needs of DDR3 are less than DDR2. DDR3 Ram is not forward or backward compitable with any type of other RAM as the operating voltages, clock speeds, timing and several other factors.

DDR3 memory has a high bandwidth interface. In addition to all these advantages, DDR3 memory type also provides the facility of having up to 8 Gigabites of memory on board. DDR3 RAM modules have different notch positions to DDR2 to prevent accidental insertion of DDR3 memory in to DDR2 slots.

Types of Computer Memories

We have come a long way from the days when heavy tape drives were used to store information to hand held little devices available today. Computer memory is nothing but the collection of data on physical devices in a digital format i:e 0's and 1's.

To classify memory, there are two types broadly, one is volatile and the other is non volatile. As their name suggests, volatile memory can store information only till it is supplied with electric energy and non volatile memory can retain the information even after the supply is disconnected.

In present day computers, RAM is a volatile but high speed memory, while Hard Drives are non volatile but low speed memory. There are many types of volatile and non volatile memories that have been developed. Among them, Different types of RAM like SDRAM, DDR, DDR2, DDR3 etc stand for volatile and flash drives, hard disks and optical storage devices are a few types that come under the non volatile category.
