JEDEC Solid State Technology Association, the global leader in standards development for the microelectronics industry, today announced the publication of JESD405-1B JEDEC Memory Module Label – for Compute Express Link (CXL ) V1.1. JESD405-1B joins JESD317A JEDEC Memory Module Reference Base Standard – for Compute Express Link (CXL ) V1.0, first introduced in March 2023, in defining the function and configuration of memory modules that support CXL specifications, as well as the standardized content for labels for these modules. JESD405-1B and JESD317A were developed in coordination with the Compute Express Link standards organization. Both standards are available for free download from the JEDEC website.
JESD317A provides detailed guidelines for CXL memory modules including mechanical, electrical, pinout, power and thermal, and environmental guidelines for emerging CXL Memory Modules (CMMs). These modules conform to SNIA (Storage Networking Industry Association) EDSFF form factors E1.S and E3.S to provide end-user friendly hot pluggable assemblies for data centers and similar server applications.
