Window RAM (WRAM)

Window RAM (WRAM), unrelated to Microsoft Windows, is high-performance video RAM that is dual-ported & has about 25% more bandwidth than VRAM but costs less. This type of RAM developed by Samsung Electronics that supports two ports. This allows a video adapter to fetch the contents of memory for display simultaneously that new bytes are being pumped in to memory. This ends in much faster display than is feasible with conventional single-port RAM.
