Compute Express Link (CXL™) Memory Module Base Standard |
JESD317 | Mar 2023 |
This standard 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.The purpose is to provide certain reference base targets for CXL™-attached memory modules to enable system design simplification, multiplicity of sources, elimination of confusion, ease of device specification, and ease of use.

DDR5 Serial Presence Detect (SPD) ContentsTerminology update Release Number: Version 1.1 |
JESD400-5A.01 | Jan 2023 |
This standard describes the serial presence detect (SPD) values for all DDR5 memory modules. In this context, “modules” applies to memory modules like traditional Dual In-line Memory Modules (DIMMs) or solder-down motherboard applications. The SPD data provides critical information about all modules on the memory channel and is intended to be used by the system's BIOS in order to properly initialize and optimize the system memory channels.
