Memory to/from Memory - 1.0 English

If a memory subsystem is connected to a video subsystem that writes to an external memory interface (to Frame Buffer) or reads from an external memory interface (from frame buffer) ONLY (thus, no live external video input/outputs), the memory subsystem must be only able to accommodate the average frame bandwidth requirements.
