| video random access memory (VRAM) Fast memory designed for storing the image to be displayed on a computer's . VRAM may be built from special memory designed to be accessed sequentially. VRAM must be fast enough to supply data to the display electronics at the speed at which the screen is scanned. Thus for example, for a of 1280x1024 eight-bit at a of 70 Hz, the would need to supply 1280x1024x70 = 90 Mbyte/s or one byte every 11 ns. The VRAM may be in order to allow the display electronics and the to access it at the same time. In an the VRAM is located on the display interface card and 0.5 - 2 MB is typical. {A VRAM Song (http://www.fweep.com/vram.html)}! (2001-02-14) |
