After seven years of development, JEDEC released the DDR4 DRAM standard (JESD79-4) last fall. The standards committee recognized the ever-increasing performance demands placed on memory and knew that a simple update wouldn't be enough.
The DDR4 architecture represents a major departure from that of previous DRAM standards, affording significant performance improvement, dramatic reductions in power demand, and compatibility with 3D architectures. Typically, a couple of years elapses between the release of a standard and broad availability of product.
Given the rapid evolution of the technology, however, DDR4 is expected to mature quite a bit more rapidly than its predecessors, with broad deployment hitting in 2014. Indeed, at the recent Intel Developers Forum (IDF), companies demonstrated working systems, like Kingston Technology's memory demo highlighting 192 GB of working 2133 MT/s DDR4 Registered DIMMs at 1.2V operating on a future Intel reference platform. We thought it was a good time to take a look at some of the offerings out on the market available to design engineers.
The following slideshow reveals that the products curently sampling go beyond memory modules to include controllers and chipsets.
