Electrically Erasable Programmable Read-Only Memory definition

(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.
