On May 14, Rambus announced the launch of a complete lineup of next-generation AI PC memory modules, specifically designed for client chipsets. This includes two new power management IC (PMIC) tailored for client-side computing: the PMIC5200 for LPDDR5 CAMM2 (LPCAMM2) memory modules and the PMIC5120 for DDR5 CSODIMM and CUDIMM memory modules.
The PMIC5200 is optimized for LPDDR power rails, delivering excellent power conversion accuracy and efficiency. The PMIC5120 currently supports data transfer rates of up to 7,200 MT/s and is designed to scale to even higher speeds in the future.
These PMICs, combined with client clock driver (CKD) and serial presence detect hub (SPD Hub), form a complete memory chipset solution for AI PC laptops, desktops, and workstations. Rambus also noted that it now provides complete interface chipsets supporting all JEDEC-standard DDR5 and LPDDR5 server and client memory module.
Rami Sethi, Senior Vice President and General Manager of Rambus Memory Interface Chips, stated that AI models are growing rapidly—by more than 10x per year—with parameters surpassing the trillion mark. This drives increasing demand for memory bandwidth and capacity, as well as lower latency to ensure processors can maintain high performance.
Sethi emphasized that Rambus has already established a leadership position in the market with its DDR5 server PMIC lineup, and is now expanding its offerings with two new client-side PMICs. Together with CKD and SPD Hub, these form a complete DDR5 and LPDDR5 memory chipset. The interface chipset solutions for LPCAMM2, DDR5 CUDIMM, and CSODIMM are designed to help customers meet the diverse module form factors, capacities, and bandwidth demands of the emerging wave of AI PC platforms.
As data transfer speeds continue to rise to support AI and other advanced workloads, the importance of signal integrity (SI) and power integrity (PI) management increases significantly. Rambus noted that with 35 years of experience in high-performance memory technology, the company has deep expertise in SI/PI, which ensures that Rambus DDR5 and LPDDR5 memory interface chips deliver outstanding signal and power stability, even in high-performance environments, supporting both server and client DIMM modules.
