GDDR5X SDRAM on an NVIDIA GeForce GTX 1080 Ti graphics card. 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.
One of the largest applications for DRAM is the main memory (colloquially called the RAM) in modern computers and graphics cards (where the main memory is called the graphics memory). It is also used in many portable devices and video game consoles.
Examples of this include the Apple II computer, the Commodore 64, the Radio Shack Color Computer, the Atari ST, and the Apple Macintosh. [citation needed] A notable exception was the IBM PC. Graphics display was facilitated by the use of an expansion card with its own memory plugged into an ISA slot.
Modern computer memory is implemented as semiconductor memory, [5] [6] where data is stored within memory cells built from MOS transistors and other components on an integrated circuit. [7] There are two main kinds of semiconductor memory: volatile and non-volatile. Examples of non-volatile memory are flash memory and ROM, PROM, EPROM, and ...
Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1] [2]

This circuitry converts an in-memory bitmap into a video signal that can be displayed on a computer monitor. In computing , a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display . [ 3 ]
A computer draws on its display by writing a bitmapped representation of the graphics into a special portion of its memory known as video memory. Without any hardware overlays, only one chunk of video memory exists which all applications must share - and the location of a given application's video memory moves whenever the user changes the ...
