Video random access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. 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.
While a computer has system RAM, most contemporary graphics cards have access to a dedicated set of memory known as VRAM. In contrast, a GPU which shares system memory has a Unified Memory Architecture, or shared graphics memory.
