  VRAM
  
      (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.
