Rambus Inc., a chip and silicon IP provider, has announced an industry-leading Power Management IC (PMIC) designed to enable low-power, high-performance LPDDR6 Small Outline Compression Attached Memory Modules (SOCAMM2). Developed in technical cooperation with customers and ecosystem partners, the PMIC expands the Rambus family of LPDDR-based server module chips and extends its leadership in advanced server memory products for future accelerated AI infrastructure.
As AI training and inference workloads scale, throughput within a given power envelope, measured in tokens per watt, has become a critical consideration for AI infrastructure. This is driving demand for purpose-built memory optimized for power efficiency, form factor and scalability. SOCAMM2 brings the power and performance benefits of LPDDR technology to a compact, modular and serviceable server-memory architecture. LPDDR6 SOCAMM2, currently in development, represents the next major evolution in LPDDR-based server memory.
Rami Sethi, senior vice president and general manager of Memory Interface Chips at Rambus, said that inference and agentic AI are driving new opportunities for memory innovation across the data center. "Our new PMIC designed for LPDDR6 SOCAMM2 builds on our leadership in server-memory power management," Sethi said. Praveen Vaidyanathan, vice president and general manager of Cloud Memory Products at Micron Technology, said LPDDRs are becoming increasingly important for next-generation AI infrastructure and welcomed Rambus' continued investment in LPDDR6 power management solutions.
Rambus provides complete memory interface chipsets for DDR- and LPDDR-based modules, including registering clock drivers, PMICs, voltage regulators, SPD Hubs and temperature sensors. It already offers an LPDDR5X SOCAMM2 chipset, and the new PMIC and SPD Hub extend that roadmap to LPDDR6 SOCAMM2. The PMIC provides advanced power conversion, sequencing, telemetry and fault protection, stepping down system voltage for the LPDDR6 DRAM and other active chips on the module. The Rambus PMIC designed for LPDDR6 SOCAMM2 is currently sampling to lead customers.
