Video random-access memory
Video Random Access Memory (VRAM) is the dedicated memory a GPU uses to store and access the pixels and other graphics data rendered on a computer monitor. It was invented by Texas Instruments in 1983.[1] 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.
