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.
