HMC Consortium – the Road to a Specification

By Dean Klein - 2012-08-16

This week the HMC consortium (HMCC) announced that the managing developers had released the first draft of an Hybrid Memory Cubeinterface specification—a sign the group is making significant progress toward making the technology widely available and adoptable. The draft itself consists of an interface protocol and short reach (SR) PHY definition and is currently only available to consortium members, or “adopters.”  Having early access to the HMC spec is one of the major draws to joining the HMCC; membership has grown steadily over the past year and now consists of a wide range of organizations from OEMs to foundries to research institutions. Now the spec is in the hands of the adopters for review, discussion and refinement, with the intent of producing a final version that will meet the needs of a broad range of technologies.

Stay tuned to find out what’s next in the process, and when and how the specification will be made public….
