graphics RAM

Hi /prog/

would it theoritcally be possible for an OS to make use of the RAM on a graphics card as system RAM, eg at boot?

The memory and CPU may both be based on silicon, but the manufacturing process is very different. You'd also reduce your yields and make your chips a lot more expensive. You could get away with putting the memory in the same package. Some newer SoCs almost do this by using the package-on-package technique for their RAM, but they're also typically limited to 512 MB.
