JEDEC Announces Publication of Serial Presence Detect Support and Module Labels Specifications to Support New Hybrid Memory (NVDIMM)
ARLINGTON, Va., USA – SEPTEMBER 10, 2019 – JEDEC Solid State Technology Association, the global leader in standards development for the microelectronics industry, today announced the publication of document release 5 of the DDR4 Serial Presence Detect (SPD) Specification. With this release of the document, the revision level of all memory types increases to UDIMM (revision 1.2), RDIMM (revision 1.3), LRDIMM (revision 1.4) and NVDIMM (revision 1.2). In addition, JEDEC issues document release 1 of the DDR4 DIMM Labels Specification.
Among the changes in the released SPD and label documents are support for the DDR4 NVDIMM-H, a proposed memory module based on a combination of DRAM and NAND Flash that provides NAND Flash accessed as a block oriented device. Often targeted at data center computer systems, NVDIMM hybrid modules are the foundational hardware supporting the growing trend for persistent memory, which enhances data resilience and system performance.
“These new specifications enable end users to identify the capabilities of this new class of hybrid module, such as capacity, speed, and access time. The DIMM label allows this information to be read by eye or by 2D barcode scanners, and the SPD enhancements allow the system CPU to read the configuration data electronically at system configuration time,” said John Kelly, JEDEC President.
