Characteristics of VRAM
- When images are to be sent to the display, they are first read by the processor & then written to the VRAM. From VRAM the data is converted by a RAM digital-to-analog converter(RAMDAC) into analog signals that are sent to the display presentation mechanism such as a Cathode Ray Tube(CRT).
- VRAM is Dual-Ported i.e. while the processor is writing a new image to VRAM, the display is reading from VRAM to refresh the current display content. This Dual-Port design is the main difference between RAM and VRAM.
- VRAM is used in a dedicated graphics card.VRAM is extremely fast & it has a large bandwidth which makes it ideal for graphics devices.
- All types of VRAM are a special arrangement of dynamic RAM(DRAM)
- VRAM is volatile memory i.e. every time when the computer is turned off, all the data stored in VRAM will be lost.
VRAM Full FormVRAM vs. RAM: What’s the Difference?
VRAM stands for Video Random Access Memory. VRAM is like RAM – except it is entirely dedicated to storing Image Data. It also acts as a buffer between the computer processor and the display. VRAM is more expensive than regular Dynamic RAM(DRAM), but VRAM can perform reads and writes at the same time.

VRAM or Video Random-Access Memory is the memory a GPU uses to store the information it needs to render images on a display. VRAM comes in many forms and having the right amount and type of it is crucial. Basically, VRAM is a type of DRAM used in Graphics cards, which increases the overall speed of Graphics Cards.
