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

Electrically Erasable Programmable Read-Only Memory

    (EEPROM) A non-volatile storage device using a
   technique similar to the floating gates in EPROMs but with
   the capability to discharge the floating gate electrically.
   Usually bytes or words can be erased and reprogrammed
   individually during system operation.

   In contrast to RAM, writing takes much longer than reading
   and EEPROM is more expensive and less dense than RAM.  It is
   appropriate for storing small amounts of data which is changed
   infrequently, e.g. the hardware configuration of an Acorn
   Archimedes.
