Rambus Inc. has introduced its family of DDR5 server power management ICs (PMICs), including an extreme current device for high-performance applications. These new server PMICs join the company’s memory interface chipset for DDR5 server memory modules, comprised of registering clock drivers (RCDs), serial presence detect (SPD) hubs and temperature sensors, to support a broad range of data-center applications.
As a critical component in the DDR5 memory architecture, the PMIC enables more memory channels, higher capacity modules and greater bandwidth, Rambus said.
The new family of DDR5 PMICs is comprised of the JEDEC extreme-current PMIC5020, the high-current PMIC5000 and the low-current PMIC5010. The PMIC5020 is designed to meet requirements for future generations of DDR5 RDIMMs for performance and capacity, Rambus said.

“Advanced data center workloads like generative AI require the highest bandwidth and capacity server RDIMMs tailored to meet ever-increasing memory needs of a growing data pipeline,” said Sean Fan, chief operating officer at Rambus, in a statement. “With the addition of this new family of server PMICs, we expand our foundational technology and offer customers a comprehensive memory interface chipset that supports multiple DDR5 server platform generations.”
The server PMICs, together with the DDR5 RCD, SPD hub and temperature sensor ICs, deliver a complete memory interface chipset for a broad range of DDR5 RDIMM configurations and use cases. Rambus recently claimed the industry’s first Gen4 RCD, enabling a 50% increase in memory bandwidth, while increasing the data rate to 7200 MT/s from the first-generation 4800 MT/s DDR5 module solutions.
Samples are available now for the DDR5 PMIC5020, PMIC5000, and PMIC5010. They are packaged in a 35-pin thermally enhanced FCQFN.
