Rambus releases DDR5 server PMIC

Rambus has announced the launch of its new DDR5 RDIMM server memory dedicated PMIC (Power Management Integrated Circuit). This new series of server PMICs provides a complete chipset solution for DDR5 RDIMM memory modules, catering to a broad spectrum of data center applications.

Sean Fan, Chief Operating Officer at Rambus, stated that advanced data center workloads, such as generative AI, require server RDIMMs with the highest bandwidth and capacity to meet the increasing demands of data pipelines. With the introduction of this next-generation server PMIC series, Rambus has expanded its product portfolio using cutting-edge chip technology, offering customers a comprehensive memory interface chipset that supports multiple generations of DDR5 server platforms.

The PMIC is a critical component in DDR5 memory architecture, enabling more memory channels, higher-capacity modules, and increased bandwidth. This server PMIC series includes three chips: PMIC5000 (compliant with JEDEC high current specifications), PMIC5010 (compliant with JEDEC low current specifications), and PMIC5020 (compliant with JEDEC extreme current specifications).

Key features include:

• Industry-leading DDR5 server PMICs designed to support the highest performance and capacity memory modules required for AI and other advanced workloads.
• The new PMIC series supports multiple generations of high-performance servers based on DDR5.
• Provides a complete memory interface chipset for DDR5 server memory modules, including Register Clock Driver (RCD), PMIC, Serial Presence Detect (SPD) hub, and temperature sensor IC.

Rambus has confirmed that the PMIC5000, PMIC5010, and PMIC5020 server PMIC series chips are now available on the market.
