Definition – What does VRAM mean?
VRAM (also known as Video RAM or Video Random Access Memory) is a high-speed array of dynamic random access memory used to store the image and video date that computer display. It is an integrated circuit that serves as the bugger between the CPU and video card. VRAM was specially designed as the high-resolution graphics adapter. Video RAM is also known as a frame buffer or video memory.
Glossary Web explains VRAM
There are multiple types of VRAM are available to use. One of the most popular kind is called Synchronous Graphic RAM. It is an inexpensive kind of RAM that is clock-synchronized that means the data can be changed in a single function rather than as a sequence of write, read and update operations. This enable background, foreground and image files to be handled more efficiently. Another type of Video RAM is Rambus Dynamic RAM that is designed by Rambus and includes branded Rambus bus that speeds up the transmission of data through it.
The third type of the VRAM is WRAM that is dual-ported and has 25% more bandwidth than standard VRAM. Multibank Dynamic RAM is another type of VRAM developed by MoSys that divides the memory into the divisions of 32 KB that can be accessed individually. It makes memory transfers more efficient and increases overall performance.
