Sort of, Kingston is a module manufacturer and they use a variety of DRAM vendors depending on the technology. Since there are few chip companies making RDRAM it's likely they're buying Samsung RDRAM from Samsung and assembling it on their own PCB's. The semiconductor companies like Samsung, Toshiba, Infineon and Micron do as much business from selling loose chips to various companies/industries as they do selling their own branded modules. Kingston is just manufacturing their own PC1066 RIMMs with Samsung components on them. Think of Kingston, Mushkin, Corsair, PNY..etc as car manufacturers, does Honda make every single part that they assemble their cars with?
