PMICs are critical to efficiently power memory modules and provide improved levels of performance for advanced computing applications. The new Rambus PMICs are the PMIC5200, for LPDDR5 CAMM2 (LPCAMM2) memory modules, and the PMIC5120, which supports DDR5 CSODIMMs and CUDIMMs.
These PMICs, alongside the Client Clock Driver (CKD) and Serial Presence Detect Hub (SPD Hub), provide a complete chipset that enables memory modules for AI PC notebooks, desktops and workstations - Rambus can now offer a complete memory interface chipset 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 optimised power efficiency,” said Rami Sethi, SVP and general manager of Memory Interface Chips at Rambus.
According to Sethi the addition of these two client PMICs rounds out a complete DDR5 and LPDDR5 client memory module chipset, which also includes the company’s 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 AI PC platforms.”
Commenting Ross Dermott, vice president of mobile product line management in Micron’s Mobile and Client Business Unit, said, “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.”
“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 important.
