Video RAM (VRAM) is a common form of dual-ported
dynamic RAM mostly used for video memory, allowing the
central processing unit (CPU) to draw the image at the same time the video hardware is reading it out to the screen. Apart from VRAM, most other types of dual-ported RAM are based on
static RAM technology. Most CPUs implement the
processor registers as a small dual-ported or multi-ported RAM. ==See also==
