Dual-ported video RAM

Dual-ported variant of dynamic RAM / From Wikipedia, the free encyclopedia

Dual-ported video RAM, or VRAM, is a dual-ported variant of dynamic RAM (DRAM), which was once commonly used to store the framebuffer in graphics adapters. Note that most computers and game consoles do not use this form of memory, and dual-ported VRAM should not be confused with other forms of video memory.
