Morphology

ROM = memory + read-only (semi-transparent) = R + O + M

The letter sequence ROM is a direct initialism of 'read-only memory', so the relation to the expansion is clear for learners who know the phrase. [Postprocessing: changed transparency from 'transparent' to 'semi-transparent' for abbreviation]

Etymology

ROM comes from the phrase read-only memory, where read means 'to look at data', only means 'not changeable', and memory means 'where data is stored'. So ROM is a part of a computer you can read but not change, and it keeps its data when the power is off.
