'''Video random-access memory''' ('''VRAM''') is dedicated computer memory used to store the [[pixel]]s and other graphics data as a [[framebuffer]] to be rendered on a computer monitor.<ref>{{cite book|title=Computer Graphics: Principles and Practice|last1=Foley|first1=James D. |last2=van Dam|first2=Andries|last3=Feiner|first3=Steven K.|last4=Hughes|first4=John F.|publisher=[[Addison-Wesley]]|year=1997|isbn=0-201-84840-6|page=859|url=https://books.google.com/books?id=-4ngT05gmAQC&dq=vram&pg=PA892}}</ref> This is often different technology than other computer memory, to facilitate being read rapidly to draw the image. In some systems this memory cannot be read/written using the same methods as normal memory; it is not [[memory mapped]].
