JEDEC publishes CXL Memory Module Base Standard called CMM

JEDEC Solid State Technology Association announced the publication of JESD317: Compute Express Link (CXL) Memory Module Base Standard, known as “CMM”. JESD317 CMM defines the specifications of interface parameters, signaling protocols, environmental requirements, packaging, and other features as reference for specific target implementations of CXL-attached memory modules, and is available for free download from the JEDEC website. CMM is designed to provide reference base targets for CXL-attached memory modules to help simplify system design and minimize industry confusion for first adoption. By leveraging established industry standard specifications from SNIA (EDSFF), PCIe, and CXL to define specific module implementations, CMM enables system providers to accommodate certain known devices while leaving room for innovation. The standard also supports system device slots designed to be compatible with both CMMs and traditional PCIe-attached NVMe drives. For a deeper dive, catch JEDEC’s session at FMS 2023 in Santa Clara, CA, on Wednesday, August 9th at 8:30AM: Breaking Past Expansion Limits: CXL-Attached Memory Standards. “The high-speed memory capabilities offered by CXL memory modules are increasingly important to the industry and critical to many emerging applications such as artificial intelligence and data analytics,” said Mian Quddus, JEDEC Board of Directors Chairman...
