2. Shared graphics memory - Wikipedia

   en.wikipedia.org/wiki/Shared_graphics_memory

   A notable exception was the IBM PC. Graphics display was facilitated by the use of an expansion card with its own memory plugged into an ISA slot. The first IBM PC to use the SMA was the IBM PCjr, released in 1984. Video memory was shared with the first 128 KiB of RAM. The exact size of the video memory could be reconfigured by software to meet ...

3. Video random-access memory - Wikipedia

   en.wikipedia.org/wiki/Video_random-access_memory

   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.

4. Dual-ported video RAM - Wikipedia

   en.wikipedia.org/wiki/Dual-ported_video_RAM

   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.

   VRAM; Dual-ported RAM. Video RAM (dual-ported DRAM) ... Another reason for the disparity is the enormous increase in the size of memory since the start of the PC ...

6. Dynamic video memory technology - Wikipedia

   en.wikipedia.org/wiki/Dynamic_video_memory...

   The amount of video memory is dependent upon the amount of pre-allocated video memory plus DVMT allocation. DVMT, as its name implies, dynamically allocates system memory for use as video memory to ensure more available resources for 2D/3D graphics performance, e.g. for graphically demanding games.

7. Memory timings - Wikipedia

   Increasing memory bandwidth, even while increasing memory latency, may improve the performance of a computer system with multiple processors and/or multiple execution threads. Higher bandwidth will also boost performance of integrated graphics processors that have no dedicated video memory but use regular RAM as VRAM.
