By reducing the I/O activity caused by paging requests, virtual memory compression can produce overall performance improvements. The degree of performance improvement depends on a variety of factors, including the availability of any compression co-processors, spare bandwidth on the CPU, speed of the I/O channel, speed of the physical memory, and the compressibility of the physical memory ...
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.
HyperMemory was a brand for ATI's method of using the motherboard's main system RAM as part of or all of the video card's video memory on their line of Radeon video cards and motherboard chipsets. It relies on new fast data transfer mechanisms within PCI Express. [1] [2] [3]
According to Nvidia, this technique will increase performance by up to 800% while retaining low latency with Nvidia Reflex. [31] Nvidia claims that DLSS 4x Frame Generation model uses 30% less video memory with the example of Warhammer 40,000: Darktide using 400MB less memory at 4K resolution with Frame Generation enabled.

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.
Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".
The Windows Task Manager utility for Windows XP and Server 2003, in its Performance tab, shows three counters related to commit charge: . Total is the amount of pagefile-backed virtual address space in use, i.e., the current commit charge.
Hardware registers are addressed in words, but sometimes only use a few bits of the word read in to, or written out to the register. Commercial design tools simplify and automate memory-mapped register specification and code generation for hardware , firmware , hardware verification , testing and documentation.
