DDR3 SDRAM in electronic engineering terms stands for double-data-rate three synchronous dynamic random access memory. This random access memory interface technology is used by computer or other digital electronic devices for high bandwidth storage of working data. One of the many dynamic random access memory (DRAM) implementations DDR3 is part of the SDRAM family of technologies. The DDR3 SDRAM is quite a significant improvement over its predecessor, the DDR2 SDRAM and its primary benefit is its ability to transfer the data at almost double the rate at which DDR2 (I/O is at 8 times the data rate of the contained memory cells) does, thereby enabling a much improved and higher bus rates and peak rates then the earlier memory technologies. However there is no noticeable reduction in latency which is a feature of the DRAM array and not due to the interface. Also the DDR3 enables a maximum module size of 16 gigabytes with chip capacities of 512 megabits and 8 gigabits. A point to note is that the DDR3 is only a DRAM interface specification, whereas the actual DRAM arrays that stores the data are similar to any other type of DRAM along with similar performance.
