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.
