    Diagram of a CPU memory cache operation. In computing, a cache (/ k æ ʃ / ⓘ KASH) [1] is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere.

  3. CPU cache - Wikipedia

    en.wikipedia.org/wiki/CPU_cache

    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.

    Cache memory is typically SRAM, while the main memory is typically DRAM. [27] RAM is volatile, meaning its contents will disappear if the computer powers down. [57] Permanent storage or non-volatile memory is typically higher capacity and cheaper than memory, but takes much longer to access.

  5. Cache performance measurement and metric - Wikipedia

    en.wikipedia.org/wiki/Cache_performance...

    A CPU cache is a piece of hardware that reduces access time to data in memory by keeping some part of the frequently used data of the main memory in a 'cache' of smaller and faster memory. The performance of a computer system depends on the performance of all individual units—which include execution units like integer, branch and floating ...

  6. Cache hierarchy - Wikipedia

    en.wikipedia.org/wiki/Cache_hierarchy

    Cache hierarchy, or multi-level cache, is a memory architecture that uses a hierarchy of memory stores based on varying access speeds to cache data. Highly requested data is cached in high-speed access memory stores, allowing swifter access by central processing unit (CPU) cores.

    Volatile memory is computer memory that requires power to maintain the stored information. Most modern semiconductor volatile memory is either static RAM (SRAM) or dynamic RAM (DRAM). [a] DRAM dominates for desktop system memory. SRAM is used for CPU cache. SRAM is also found in small embedded systems requiring little memory.
