Rambus Inc. (NASDAQ: RMBS), a premier chip and silicon IP provider making data faster and safer, today announced its complete DDR5 9600 Client Memory Module Chipset for high-performance CUDIMM, CQDIMM and CSODIMM modules in future generation AI PCs. The chipset includes the new Gen 2 Client Clock Driver (CKD02), delivering breakthrough performance with support for PC memory module operation of up to 9600 MT/s, Power Management IC (PMIC5120) and Serial Presence Detect Hub (SPD Hub).
With the rise of agentic AI, PCs now plan, execute, and adapt workflows in real time. These workloads require persistent context, concurrent processing, and continuous data movement between the processor and system memory requiring significant increases in both bandwidth and capacity. At the same time, scaling DDR5 memory beyond 6400 MT/s introduces new technical challenges, including signal degradation, clock jitter, and timing instability. To address these challenges, the industry is transitioning to clocked memory modules, including CUDIMM and CQDIMM for desktops and CSODIMM for laptops, which incorporate an on-module client clock driver (CKD) to condition and redistribute the clock signal.
