From The Collaborative International Dictionary of English v.0.48 :

  cache \cache\ (k[a^]sh), n. [F., a hiding place, fr. cacher to
     conceal, to hide.]
     1. A hole in the ground, or other hiding place, for
        concealing and preserving provisions which it is
        inconvenient to carry. --Kane.
        [1913 Webster]
     2. That which is hidden in a cache[2]; a hoard; a stockpile.
     3. (Computers) A form of memory in a computer which has a
        faster access time than most of main memory, and is
        usually used to store the most frequently accessed data in
        main memory during execution of a program.

From The Free On-line Dictionary of Computing (30 December 2018) :

  cache memory
      /kash/ A small fast memory holding
     recently accessed data, designed to speed up subsequent access
     to the same data.  Most often applied to processor-memory
     access but also used for a local copy of data accessible over
     a network etc.
     When data is read from, or written to, main memory a copy is
     also saved in the cache, along with the associated main memory
     address.  The cache monitors addresses of subsequent reads to
     see if the required data is already in the cache.  If it is (a
     cache hit) then it is returned immediately and the main
     memory read is aborted (or not started).  If the data is not
     cached (a cache miss) then it is fetched from main memory
     and also saved in the cache.
     The cache is built from faster memory chips than main memory
     so a cache hit takes much less time to complete than a normal
     memory access.  The cache may be located on the same
     integrated circuit as the CPU, in order to further reduce
     the access time.  In this case it is often known as primary
     cache since there may be a larger, slower secondary cache
     outside the CPU chip.
     The most important characteristic of a cache is its hit rate
     - the fraction of all memory accesses which are satisfied from
     the cache.  This in turn depends on the cache design but
     mostly on its size relative to the main memory.  The size is
     limited by the cost of fast memory chips.
     The hit rate also depends on the access pattern of the
     particular program being run (the sequence of addresses being
     read and written).  Caches rely on two properties of the
     access patterns of most programs: temporal locality - if
     something is accessed once, it is likely to be accessed again
     soon, and spatial locality - if one memory location is
     accessed then nearby memory locations are also likely to be
     accessed.  In order to exploit spatial locality, caches often
     operate on several words at a time, a "{cache line" or "cache
     block".  Main memory reads and writes are whole cache lines.
     When the processor wants to write to main memory, the data is
     first written to the cache on the assumption that the
     processor will probably read it again soon.  Various different
     policies are used.  In a write-through cache, data is
     written to main memory at the same time as it is cached.  In a
     write-back cache it is only written to main memory when it
     is forced out of the cache.
     If all accesses were writes then, with a write-through policy,
     every write to the cache would necessitate a main memory
     write, thus slowing the system down to main memory speed.
     However, statistically, most accesses are reads and most of
     these will be satisfied from the cache.  Write-through is
     simpler than write-back because an entry that is to be
     replaced can just be overwritten in the cache as it will
     already have been copied to main memory whereas write-back
     requires the cache to initiate a main memory write of the
     flushed entry followed (for a processor read) by a main memory
     read.  However, write-back is more efficient because an entry
     may be written many times in the cache without a main memory
     When the cache is full and it is desired to cache another line
     of data then a cache entry is selected to be written back to
     main memory or "flushed".  The new line is then put in its
     place.  Which entry is chosen to be flushed is determined by a
     "{replacement algorithm".
     Some processors have separate instruction and data caches.
     Both can be active at the same time, allowing an instruction
     fetch to overlap with a data read or write.  This separation
     also avoids the possibility of bad cache conflict between
     say the instructions in a loop and some data in an array which
     is accessed by that loop.

     sector mapping, set associative cache.
