Definitions of programmable read-only memory words

noun Technical meaning of programmable read-only memory (storage) (PROM) A kind of ROM which can be written using a PROM programmer. The contents of each bit is determined by a fuse or antifuse. The memory can be programmed once after manufacturing by "blowing" the fuses, which is an irreversible process. Blowing a fuse opens a connection while blowing an antifuse closes a connection (hence the name). Programming is done by applying high-voltage pulses which are not encountered during normal operation. 1
noun programmable read-only memory (electronics) a type of read-only memory which can be written to once (write-once read-many memory / WORM), and thereafter becomes fixed in value. 0
