... Video RAM
Video RAM. This is RAM that is dedicated to handling the visuals and graphics on your notebook computer. This is helpful if you want to play a lot of the latest 3D video games on your notebook.
Video RAM or VRAM is special memory that's used by video adapters on your notebook. It is somewhat different from ordinary RAM because it can be accessed by two different devices at once - enabling screen updates while the video processor processes new data. VRAM provides better graphics but is more expensive than ordinary RAM.
Gamers please note! There is also a special kind of VRAM, known as Windows RAM (WRAM) - which gives even better visual performance than VRAM.
To confuse things even more - there are other types of Video RAM you should be aware of:
Synchronous Graphics RAM (SGRAM) - is a low-cost video memory and it's only single ported, thus moderately fast.
Multibank Dynamic RAM (MDRAM)- produced by MoSys is a very high-performance RAM that uses multiple memory 'banks' which increases overall performance.
Rambus Dynamic RAM (DRAM)- made by Rambus is a video RAM that's optimized for video streaming.
