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

random-access memory
RAM

    (RAM) (Previously "direct-access memory").  A data
   storage device for which the order of access to different
   locations does not affect the speed of access.  This is in
   contrast to, say, a magnetic disk, magnetic tape or a
   mercury delay line where it is very much quicker to access
   data sequentially because accessing a non-sequential location
   requires physical movement of the storage medium rather than
   just electronic switching.

   In the 1970s magnetic core memory was used and some
   old-timers still call RAM "core".  The most common form of RAM
   in use today is semiconductor integrated circuits, which
   can be either static random-access memory (SRAM) or dynamic
   random-access memory (DRAM).

   The term "RAM" has gained the additional meaning of
   read-write.  Most kinds of semiconductor read-only memory
   (ROM) are actually "random access" in the above sense but are
   never referred to as RAM.  Furthermore, memory referred to as
   RAM can usually be read and written equally quickly
   (approximately), in contrast to the various kinds of
   programmable read-only memory.  Finally, RAM is usually
   volatile though non-volatile random-access memory is also
   used.

   Interestingly, some DRAM devices are not truly random access
   because various kinds of "page mode" or "column mode" mean
   that sequential access is faster than random access.

   The humorous expansion "Rarely Adequate Memory" refers to the
   fact that programs and data always seem to expand to fill the
   memory available.
