 for video memory
From The Free On-line Dictionary of Computing (30 December 2018) :

  video memory
  
      The memory in a computer's graphics adaptor, used
     to store the image displayed on a bitmap display.  Often
     this is built using VRAM chips.  There is normally a simple
     correspondence between groups of bits in video memory and
     the dots or "{pixels" on the screen, such that writing to a
     given group of bits will alter the appearance of a single dot.
     If each pixel corresponds to eight bits then it can have any
     of 256 colours (or shades of grey on a monochrome display).
  
     The video display electronics is responsible for reading the
     data from video memory and converting it into the necessary
     signals to drive the display.  Often this includes a colour
     palette which converts pixel values into RGB triplets.
