DDR3 will hold its position as the leading technology in 2011’s DRAM market for at least three years before an evolution into the next generation.
According to IHS iSuppli, DDR3 will make up 89 percent of all the 808 million DRAM module units shipped in 2011. It has quickly become the dominant technology in the segment, holding 67 percent of units shipped for 2010 and 24 percent in 2009.
DDR2 will still be floating about, accounting for just nine percent of 2011’s module market. Last year it managed a respectable but weakening 29 percent. It was at the top of its game for about four years before DDR3 became the attractive option. The rest of the DRAM market will be legacy DDR.
DDR3 will keep its grip during the years to come, with shipment levels expected to reach as high as 94 percent of the whole market in 2013. 2014 will see its cycle slow and reach the inevitable decline. IHS iSuppli’s research points to DRAM module density reaching 8 GB from just 1 GB in 2009.
2014 will see DDR4 making in-roads into the market with projections sitting at 12 percent market share. In 2015, DDR4 will have already taken the lion’s share at 56 percent. DDR2, DDR3, DDR4 – seems like a reasonable progression to us.
Meanwhile, in the enterprise channel, LRDIMM – or Load-reduced Dual In-line Memory Modules – are just about ready to make their appearance in high performance servers, running at higher densities of 16GB. They will offer a significant boost to the memory of enterprise servers and mainframes, getting around problems like signal integrity degradation and performance woes that come with high memory densities.
Though LRDIMMs will be handy for continued loading, as well as increases in megabyte capacity for speciality systems, they won’t be compatible with older machines.
