Types of Video Memory
- Multibank DRAM (MDRAM): MDRAM divides the memory into the smaller sections called the banks. This allows the computer to access the different parts of the memory at the same time making it faster. MDRAM is also the cheaper since you only need the amount that required for your screen resolution.
- Rambus DRAM: RDRAM has a special pathway to speed up the transfer of data from the VRAM to the part that displays it on the screen.
- Synchronous Graphics RAM (SGRAM): SGRAM works by opening up two separate memory spaces at once instead of just one. This makes it act a bit like faster dual-ported memory even though it’s single-ported.
- Window RAM (WRAM): WRAM is a very fast dual-ported VRAM that can transfer data quicker than regular VRAM. WRAM is good for handling high resolutions with true color. The name has nothing to do with Microsoft Windows.
What is video memory ?
Video memory is a type of memory used to store image data that the computer’s GPU (Graphics Processing Unit) needs. Video memory is important for ensuring that graphics work smoothly and efficiently, especially in graphics applications like video games, 3D modeling software, and high-definition video playback.
