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.
COASt, an acronym for "cache on a stick", is a packaging standard for modules containing SRAM used as an L2 cache in a computer. COASt modules look like somewhat oversized SIMM modules. These modules were somewhat popular in the Apple and PC platforms during early to mid-1990s, but with newer computers cache is built into either the CPU or the ...
ReadyBoost enables NAND memory mass storage CompactFlash, SD card, and USB flash drive devices to be used as a cache between the hard drive and random access memory in an effort to increase computing performance. ReadyBoost relies on the SuperFetch and also adjusts its cache based on user activity.
Caused by a cache miss whilst a cache is already full. cache hit Finding data in a local cache, preventing the need to search for that resource in a more distant location (or to repeat a calculation). cache line A small block of memory within a cache; the granularity of allocation, refills, eviction; typically 32–128 bytes in size. cache miss
DayStar Digital, Inc., was a company founded in 1983 by Andrew Lewis as a subcontract manufacturer of electronic assemblies and circuit boards.In 1986, the company released memory upgrades for Apple Macintosh (Mac) computers as its first products, and in 1987, DayStar began to market processor upgrades exclusively for the Mac, the first being for the Macintosh II computer.
As of August 2017, microSD cards with a capacity up to 400 GB (400 billion bytes) are available. [ 65 ] [ 66 ] The same year, Samsung combined 3D IC chip stacking with its 3D V-NAND and TLC technologies to manufacture its 512 GB KLUFG8R1EM flash memory package with eight stacked 64-layer V-NAND chips.
