PROM
Author: Gabriel Torres Last Updated: December 28, 2005

Programmable Read-Only Memory

PROM is a kind of ROM memory. ROM memory is a kind of integrated circuit containing a program inside. This program cannot be altered or erased, hence its name ”read-only“.  Another feature of ROM memories is that their contents aren’t lost when their power is turned off, contrary to what happens to RAM memories.

PROM circuits are sold ”virgin“ and the program is recorded using an appropriated recorder, and it is not possible to erase it, i.e. it is not possible to reprogram the chip.
