Video and audio streaming applications often have a hit ratio near zero, because each bit of data in the stream is read once (a compulsory miss), used, and then never read or written again. Many cache algorithms (particularly LRU ) allow streaming data to fill the cache, pushing out information which will soon be used again ( cache pollution ...
Specialized DRAM chips, such as pseudostatic RAM (PSRAM), have all the refresh circuitry on the chip, and function like static RAM as far as the rest of the computer is concerned. [ 8 ] Usually the refresh circuitry consists of a refresh counter which contains the address of the row to be refreshed which is applied to the chip's row address ...
Memory timings or RAM timings describe the timing information of a memory module or the onboard LPDDRx. Due to the inherent qualities of VLSI and microelectronics, memory chips require time to fully execute commands. Executing commands too quickly will result in data corruption and results in system instability.
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.
There's a video of it all in action below, wherein you'll find a guy whose spelling and grammar are somehow more questionable than his choice in haircuts. Tinder adds GIF support to show matches ...
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.

The term frame buffer is thus often used interchangeably when referring to this RAM. The CPU sends image updates to the video card. The video processor on the card forms a picture of the screen image and stores it in the frame buffer as a large bitmap in RAM. The bitmap in RAM is used by the card to continually refresh the screen image. [15]
