JEDEC Publishes DDR4 NVDIMM-P Bus Protocol Standard

ARLINGTON, Va., USA – February 17, 2021JEDEC Solid State Technology Association, the global leader in standards development for the microelectronics industry, today announced the publication of JESD304-4.01 DDR4 NVDIMM-P Bus Protocol. The JEDEC NVDIMM-P standard will enable the industry to create advanced memory solutions that benefit from the enhanced system performance and novel data availability offered by Persistent Memory devices. JESD304-4.01 DDR4 NVDIMM-P is available for download from the JEDEC website.

As demand for DRAM capacity and bandwidth continues to grow, Hybrid DIMM technologies such as NVDIMM-P provide an innovative method for attaching emerging Persistent Memory in computing systems. Combining the access speeds of DDR with the reliability and capacity of non-volatile memories gives design engineers a new approach to data management. Much more than a standard DIMM specification, NVDIMM-P provides a full transactional interface protocol compatible with standard DRAM DIMMs along with a firmware programming model for the modules. NVDIMM-P simultaneously maximizes both re-use and flexibility by minimizing system host changes, providing an interface of the lowest latency to emerging memory, and offering flexible support for varied Persistent Memory media characteristics and use cases.

NVDIMM-P enables:

Key features include:

DDR4 IP Cores

Mian Quddus, Chairman of the JEDEC Board of Directors, said: “Increasing performance requirements are driving the need for more advanced technologies, and the standardization of the new generation Persistent Memory modules such as NVDIMM-P will be essential to fulfilling those needs.” He added, “We invite all interested engineers worldwide to visit the JEDEC website for more information about JEDEC membership and participation in JEDEC standards-setting activities.”


JEDEC is the global leader in the development of standards for the microelectronics industry. Thousands of volunteers representing over 300 member companies work together in more than 100 JEDEC technical committees and task groups to meet the needs of every segment of the industry, manufacturers and consumers alike. The publications and standards generated by JEDEC committees are accepted throughout the world. All JEDEC standards are available for download from the JEDEC website.
