What is DDR3 Memory? Is DDR4 Better Than DDR3?

In 2006, several DRAM manufacturers announced that they were supplying the industry’s first DDR3 devices and modules to leading PC developers by early 2007 and that DDR3s would be available by the end of 2007 and early 2008. While a DDR3 memory might seem like much to us today in 2018 because of the release of the DDR4 in 2014, in 2006, the DDR3 SDRAMs were exciting.

The DDR3 SDRAM stands for double date rate type three synchronous dynamic random-access memory. The successor to the DDR and DDR2 and predecessor to the DDR4, the DDR3 is a type of high-bandwidth data storage. With speeds twice that of the highest speed DDR2, higher bandwidth, and an increase in performance at low power, the DDR3 was a revelation in 2006. DDR3 SDRAM devices could transfer data at up to 1600 Mbps, double that of the DDR2 at 800 Mbps, but more efficiently with a supply voltage of only 1.5 V, down from the 1.8 V of the DDR2. In addition, with the downgrade of the supply voltage comes a reduction in power consumed and heat generated that could otherwise damage the component. Overall, in comparison to its predecessors, the DDR3 was more efficient, something that the DDR4 would take further 7 years later.

In addition to improvements made from the DDR2 SDRAM, DDR3 also introduced an asynchronous reset pin, self-calibration, system leveling, and a CAS Write Latency per speed bin. Then, in 2013, DRAM manufacturers announced that 2014 would see the processor of the DDR3, the DDR4. Even more than the DDR3, the DDR4 wowed the electronics industry with better performance and new capabilities. Effectively, the DDR4 rendered even the DDR3 obsolete.
