Video Memory

Video memory is a term generally used in computers to describe some form of writable memory, usually RAM, dedicated to the purpose of holding the information necessary for a graphics card to drive a display device. In modern 3D graphics cards, the video memory may also hold 3D vector data, textures, backbuffers, overlays and GPU programs, and sometimes takes the form of a Shared Memory Architecture (SMA).

Famous quotes containing the words memory and/or video:

    Why is it that we have enough memory to recollect the most minute circumstances of something that has happened to us, but not enough to remember how many times we have recounted them to the same person?
    François, Duc De La Rochefoucauld (1613–1680)

    I recently learned something quite interesting about video games. Many young people have developed incredible hand, eye, and brain coordination in playing these games. The air force believes these kids will be our outstanding pilots should they fly our jets.
    Ronald Reagan (b. 1911)
