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.[1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
Relation to GPUs

Many modern GPUs rely on VRAM. In contrast, a GPU that does not use VRAM, and relies instead on system RAM, is said to have a unified memory architecture, or shared graphics memory.
System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs,[2][3] and to achieve lower latency, since VRAM is physically closer to the GPU die.[4]
Modern VRAM is typically found in a BGA package[5] soldered onto a graphics card.[6] The VRAM is cooled along with the GPU by the GPU heatsink.[7]
