Rambus designs the memory chips and IP that make data move fast inside servers, plus licenses patents for memory and security tech. Think of them as the plumbing supplier for AI-era computing.
Money comes from selling DDR5 memory interface chips and licensing silicon IP and patents. Gross margin is 78.27% TTM, net margin 31.69% TTM, with recurring royalty revenue from licensing.
