video random access memory
     
         vram fast memory designed for storing the image
        to be displayed on a computer's monitor.  vram may be built
        from special memory integrated circuits designed to be
        accessed sequentially.
     
        vram must be fast enough to supply data to the display
        electronics at the speed at which the screen is scanned.  thus
        for example, for a resolution of 1280x1024 eight-bit
        pixels at a refresh rate of 70 hz, the video memory
        would need to supply 1280x1024x70 = 90 mbyte/s or one byte
        every 11 ns.  the vram may be dual ported in order to allow
        the display electronics and the cpu to access it at the same
        time.
     
        in an ibm pc the vram is located on the display interface
        card and 0.5 - 2 mb is typical.
