64GB DDR4 very-low-profile RDIMM and mini-RDIMM modules now available

If there's one thing that's certain -- in addition to death and taxes, of course -- it's that designers want to have as much memory as possible in their embedded systems. Of course, some systems -- like sensor nodes on the edge of the Internet of Things (IoT) -- scrape by on a few thousand, or a few hundred thousand, bytes. By comparison, many other systems can take advantage of as much memory as they can lay their metaphorical hands on.

When it comes to embedded systems and their memory, there's an interrelated two-pronged trend involving opposing yet complementary forces -- the footprint of the systems in the form of single board computers (SBCs) and the like just keeps on getting smaller, while the demand for the memory they contain is increasing in leaps and bounds.

Until recently, the maximum size DDR4 memory module was 32GB. This meant that designers had to either stay with lower capacities or "make room for daddy" in order to accommodate extra memory modules in their space-constrained systems.

Furthermore, given that systems in the embedded world tend to be deployed in harsh, far-flung, difficult-to-access and hard-to-service environments (e.g., oil rigs and cellular base stations), their memory modules need to support an industrial temperature range of -40 to 85°C.

All of which leads us to the fact that the folks at Virtium -- a leading solutions-driven provider of industrial solid state drive (SSD) and memory products -- have just announced that they have doubled the top-end capacity of their very-low-profile (VLP) RDIMM and Mini-RDIMM DDR4 memory modules. Featuring the PC4-2400 interface and the industry’s smallest form factor, Virtium’s latest VLP RDIMM and Mini-RDIMM memory modules now feature capacities up to an industry-high 64GB, thereby ushering in a new generation more-powerful embedded systems with broader memory options.

Virtium’s chip placement technology enables maximum density of chips placed in the smallest of footprints, and its new VLP RDIMM and Mini-RDIMM modules were developed to provide high-performance memory to a wide range of space-constrained systems, including height-restricted blade servers, 1U racks, single-board computers, and mezzanine cards.

As an option, these modules can also be provided with conformal coating and extreme-temperature, accelerated-burn-in for zero-downtime applications. For more information, visit Virtium.com.
