(programmable read-only memory) (n., adj.) A permanent memory chip programmed by the user rather than at the chip manufacturer, as is true with a ROM. You need a PROM programmer or burner to write data onto a PROM. PROM has been mostly replaced by EPROM , a type of PROM that can be erased by ultraviolet light and reprogrammed.
