JEDEC Sets the Bar Higher with JESD318 CAMM2
In a monumental stride towards advancing memory technology, JEDEC Solid State Technology Association has unveiled its latest triumph: the JESD318 Compression Attached Memory Module (CAMM2) Common Standard. This groundbreaking standard, available for download from the JEDEC website, defines the electrical and mechanical requirements for two key memory technologies in a single, comprehensive document — the Double Data Rate, Synchronous DRAM Compression-Attached Memory Modules (DDR5 SDRAM CAMM2s) and Low Power Double Data Rate, Synchronous DRAM Compression-Attached Memory Modules (LPDDR5/5X SDRAM CAMM2s).
Versatility Tailored for Distinct Needs
DDR5 CAMM2s are strategically engineered for performance notebooks and mainstream desktops, while LPDDR5/5X CAMM2s extend their reach to a broader spectrum, including various notebooks and specific server market segments. Despite serving diverse use cases, JESD318 CAMM2 introduces a common connector design for both DDR5 and LPDDR5/5X, underlining its commitment to modularity and adaptability across the industry.
However, it is crucial to note that the pinouts for each memory technology differ. Intentional variations in mounting procedures between DDR5 and LPDDR5/X CAMM2s are in place to prevent the inadvertent installation of modules in incompatible slots. This meticulous design ensures seamless integration into different motherboard configurations, fostering a more flexible and reliable computing environment.
Scalability for Future Innovation
One of the highlights of the JESD318 CAMM2 is its support for stackable CAMM2s, available in dual-channel (DC) and single-channel (SC) configurations. The ingenious split of the dual-channel CAMM2 connector into two single-channel connectors opens up new possibilities. Designers can now elevate the CAMM2 to different levels, with each connector half supporting a distinct DDR5 memory channel at varying heights. This scalability, from single-channel and dual-channel setups to potential multi-channel configurations, promises a substantial boost in memory capacity.
“The development of JEDEC CAMM2 exemplifies JEDEC’s commitment to serving the industry with innovative standards. CAMM2 is versatile across various use cases and is designed with future scalability in mind,” stated Mian Quddus, Chairman of JEDEC’s Board of Directors.
Tom Schnell, Chairman of JEDEC’s CAMM Task Group, echoed this sentiment, affirming that “JEDEC CAMM2 is positioned to support and drive next-generation products, offering designers an extensive range of modularity options. As technology evolves, memory requirements grow, and JEDEC CAMM2 is at the forefront of addressing these demands. The support for future multi-channel configurations ensures that designers and manufacturers are not just meeting current needs but are also well-prepared for the evolving landscape of memory solutions.”
Looking Ahead with JEDEC
JEDEC continues to be a trailblazer in the microelectronics industry, with thousands of volunteers from over 350 member companies collaborating in over 100 committees and task groups. These efforts are focused on meeting the ever-evolving needs of the industry, ensuring that manufacturers and consumers alike benefit from the cutting-edge standards set by JEDEC.
As technology marches forward, JEDEC stands as a beacon of innovation, providing standards that not only meet the present but also anticipate and prepare for the challenges and opportunities that lie ahead. All JEDEC standards, including the groundbreaking JESD318 CAMM2, are available for download from the JEDEC website, marking a commitment to openness, accessibility, and collaboration in shaping the future of memory technology.
