LPCAMM2 Memory Module with Rambus PMIC and SPD Hub ICs

These PMICs, alongside the Client Clock Driver (CKD) and Serial Presence Detect Hub (SPD Hub), comprise a complete chipset offering to enable memory modules for AI PC notebooks, desktops and workstations. Further, with the addition of these new PMICs, Rambus now offers complete memory interface chipsets for all JEDEC standard DDR5 and LPDDR5 memory modules for both servers and clients.

“The proliferation of AI-enabled client systems is driving new memory subsystem requirements that demand modules delivering higher bandwidth and optimized power efficiency,” said Rami Sethi, SVP and general manager of Memory Interface Chips at Rambus. “Having established a leadership position with the introduction of our DDR5 server PMIC family, we’re now extending that leadership with two client PMICs that round out a complete DDR5 and LPDDR5 client memory module chipset, which also includes our Client Clock Driver and SPD Hub. Our memory interface chipsets, for LPCAMM2 and DDR5 CUDIMMs and CSODIMMs, enable our customers to address the broad range of form factor, capacity and bandwidth options required by this next wave of exciting AI PC platforms.”

“Micron’s first-to-market leadership in LPCAMM2 technology is advancing computing performance in AI PCs while disrupting the industry with unprecedented modularity and flexibility,” said Ross Dermott, vice president of mobile product line management in Micron’s Mobile and Client Business Unit. “Rambus’ latest PMIC solutions are a critical component in our next-generation LPCAMM2 modules — allowing us to push the boundaries of memory performance and strengthen our gen-over-gen LPCAMM2 industry leadership.”

“AI PCs powered by Intel processors ushers in a new era of productivity, creativity and entertainment experience. The latest Intel® Core™ Ultra processors family features cutting-edge AI enhancements, increased efficiency and performance improvements,” said Dimitrios Ziakas, VP of Memory & IO Technologies, Intel Corporation. “From ultra-thin notebooks to the most powerful workstations, Rambus memory interface chips can support the multitude of form factors both businesses and consumers will employ to harness the power of AI.”

“As the rapid evolution of AI reshapes the PC market, the demands on memory bandwidth and capacity will only accelerate,” said Brandon Hoff, executive analyst at IDC. “High-performance LPDDR5 and DDR5 memory modules, enabled by advanced memory interface chipsets, will be key to unlocking the tremendous possibilities of AI.”

As data rates continue to rise to support the needs of AI and other advanced workloads, signal integrity (SI) and power integrity (PI) management become increasingly vital. With 35 years of high-performance memory experience, Rambus is renowned for its SI/PI expertise. This expertise helps enable DDR5 and LPDDR5 memory interface chips to deliver superior signal integrity and power efficiency at higher performance for server and client DIMMs.

To deliver the highest levels of performance and reliability, Rambus offers complete memory interface chipsets for all JEDEC standard DDR5 and LPDDR5 memory modules, including:

• LPCAMM2 Chipset: PMIC5200, SPD Hub
• DDR5 CSODIMM and CUDIMM Chipset: Client Clock Driver (CKD), PMIC5120, SPD Hub
• DDR5 RDIMM 4800 – 8000 Chipsets: Registering Clock Driver (RCD), PMIC, Serial Presence Detect Hub (SPD Hub), Temperature Sensor ICs (TS)
• DDR5 MRDIMM 12800 Chipset: Multiplexing Registering Clock Driver (MRCD), Multiplexing Data Buffer (MDB), PMIC, SPD Hub, TS
