Micron and the future of GDDR memories

Over the last few months there has been a lot of news from Micron for GDDR memories for Graphic cards, game consoles and network programs are heard. According to reports, Micron has managed to break the bandwidth record of 16 Gb/s by using the latest generation of GDDR5X memory. Micron has also released its plans to develop GDDR5 and GDDR6, GDDR6 memories soon. And after a few seasons, they will enter the field of competition. Meanwhile, GDDR5 memories will be used for a long time. DRAM memories for graphics cards are one of the hot topics in the semiconductor and hardware industry; Because the need for high memory bandwidth is one of the growing needs of the technology world, and various companies are trying to meet this need by offering a variety of memories. For example, SK Hynix and Samsung first and second generation HBM memories in 2015 and 2016 for Users launched professional systems and applications such as High Performance Processing (HPC) . In the meantime and last year, Micron also released its GDDR5X memory for professional graphics cards. Currently, HBM memories offer the highest potential bandwidth for various applications; But their multilayer chips and 2.5D packaging make HBM costs high. Therefore, the choice of this type of memory depends on the application and user needs. However, the improved packaging architecture of conventional graphics cards, which is the BGA type, continues to improve and its efficiency will increase over the coming years. All these factors make the usual graphics memory to continue to compete.

      • Micron begins mass production of GDDR5X memory
      • GDDR5X standard finalization; Graphics memory with a speed of 14 GB/s
      • Nvidia in The next generation of graphics cards will still use GDDR5X
      • SK Hynix to launch GDDR6 memory for graphics cards in early 2018 introduced GDDR5X, it has two goals in mind: to reach 10 and 12 Gbps bandwidth in the first step, and then increase the bandwidth to 16 Gbps in the long term. First, Micron company presented its ICs with 10 and 11 gigabit bandwidth; But this year, it was able to produce memories with a frequency of 12 gigabits per second in a laboratory. The second model is used on Titan XP graphics cards. The important point is that the specialists of the Micron company in the development center of this company located in Munich, have recently been able to launch this type of memory with a bandwidth of 16 gigabits per second. The market has not been affected, two of its important effects can be stated. The first point is that Micron has been able to improve its work process in such a way that the result is the production of memories with a bandwidth of 16 gigabits per second, and this is exactly what technology needs today. The second important point is the potential of GDDR5X memories; Therefore, Micron’s hardware partners may offer new products with faster memory.

        Micron has been working on GDDRX memories and the physical implementation of such memories for several years; And on the other hand, it is working on GDDR6 memories so that it can launch them in early 2018. In fact, GDDR5X memory is not much different from GDDR6. The default architecture of both is based on 16nm manufacturing technology, and the key reason for increasing their efficiency compared to GDDR5 memories is this manufacturing technology. At the same time, GDDR6 also benefits from the feature of being 2 channels, and in applications that can use this feature, we will see improved performance.


        Memory type GDDR5 GDDR5X GDDR6
        Capacity 4 to 8 GB 8 GB 8 GB
        5 ​​to 8 GB/s 10 to 12 GB/s More than 12 GB/s
        Building technology More than 20, 20 and 16nm 20nm 16nm

        However, Micron will use the 16nm production line to produce GDDR6 memories, which means more potential for increased bandwidth. It is interesting to know that Micron also makes its new GDDR5 memories with 16nm manufacturing technology. This means that GDDR5 memory will continue to be used in graphics cards and game consoles for several years. It has been able to achieve a bandwidth of 16 gigabits per second in GDDR5X memories. Micron is also going to work on 16nm manufacturing technology to produce GDDR5 and GDDR6 memories by 2018.
