New JEDEC Standards for CXL Memory Technology
ARLINGTON, Va. – The JEDEC Solid State Technology Association, a prominent organization specializing in microelectronics standards, has recently announced two new standards that support Compute Express Link (CXL) technology. This development completes a comprehensive set of four standards, offering significant flexibility for creating a variety of CXL memory products. You can download the newly released documents for free from the official JEDEC website.
Details of the New Standards
JESD319: JEDEC Memory Controller Standard
The JESD319 standard details specifications, interface parameters, signaling protocols, and essential features for a CXL Memory Controller ASIC. It specifically focuses on memory expansion applications using the CXL 3.1 standard. This standard lays the groundwork for essential functionality while also leaving room for future advancements and tailored enhancements.
JESD325: JEDEC Memory Device Management Standard
Alongside JESD319, the JESD325 standard outlines critical specifications for managing CXL memory devices. This standard is particularly aimed at field-replaceable CXL memory that works with PCIe Gen 5, ensuring it aligns with the CXL 2.0 Specification and beyond. Key aspects covered by JESD325 include:
- Management Interface Requirements across various layers
- Security Requirements, such as Signature and Hashing Algorithms
- Guidelines for Management Sensors and Controls
- Thermal Management Requirements to ensure effective device performance
- FRU Vital Product Data content requirements
Supporting Existing Standards
The newly introduced JESD319 and JESD325 standards complement previous standards like JESD317A and JESD405-1B, which help reinforce the foundation for CXL-related technologies. The JESD317A standard focuses on a Memory Module Reference Base specific to CXL, while JESD405-1B addresses the Memory Module Labeling aspect relevant to CXL.
Industry Insights and Reactions
Mian Quddus, Chairman of the JEDEC Board of Directors, underscored the importance of these new updates, saying, "The recent unveiling of JESD319 and JESD325 completes a robust suite of standards supporting the continuous development of CXL technology. This comprehensive suite provides unparalleled flexibility for creating a wide range of CXL memory products, from fully compliant devices to unique solutions that meet essential management criteria."
