DDR SDRAM (double data rate synchronous dynamic random access memory) is a class of memory integrated circuit used in computers. It achieves nearly twice the bandwidth of the preceding [single data rate] SDRAM by double pumping (transferring data on the rising and falling edges of the clock signal) without increasing the clock frequency.

Currently, DDR memory technology has grown rapidly. The most visible in terms of development of this type of memory is the capacity and speed. However, the development of DDR is not only in terms of capacity and speed alone, as well as lower power consumption. Associated with the energy crisis in the future, manufacturers are required to create a neighborhood-friendly technology and power saving.

DDR development has now reached the fourth generation. DDR4 is the final output of the memory type, and will soon be available on the market, but who knows when. The leading memory manufacturers have begun competing to develop and produce this type of memory.

DDR4 memory is said to be high speed, high capacity, but low power consumption. Pace of technological change is very difficult to followed, as every manufacturer vying for the best show, by enticing consumers.

Any new type of memory, then the price of each memory is very expensive. DDR4 memory is expected to be very expensive, when he first launched into the market. To be able to use the memory, the consumer must have to need the money. However, we can wait a few years after a new type of memory is outstanding. Surely the price will be more expensive.
