Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
[citation needed] With this capability integrated into the network, applications can take advantage of a very large amount of memory to improve overall performance, system utilization, increase memory usage efficiency, and enable new use cases. Software on the memory pool nodes (servers) allows nodes to connect to the memory pool to contribute ...
Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
One technique used on early IBM XT computers was to install additional RAM into the video memory address range and push the limit up to the start of the Monochrome Display Adapter (MDA). Sometimes software or a custom address decoder was required for this to work. This moved the barrier to 704 KB (with MDA/HGC) or 736 KB (with CGA). [6] [7]
Motherboard of the NeXTcube computer, 1990, with 64 MiB main memory DRAM (top left) and 256 KiB of VRAM [2] (lower edge, right of middle) Dynamic random-access memory ( dynamic RAM or DRAM ) is a type of random-access semiconductor memory that stores each bit of data in a memory cell , usually consisting of a tiny capacitor and a transistor ...
In computing, a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display. [3] The screen buffer may also be called the video buffer, the regeneration buffer, or regen buffer for short. [4] Screen buffers should be distinguished from video memory.
