I do not think there are some other differences

PROM's cost more, so are used in small volume manufacturing or in testing stages, on data that will rarely change.

Hi Friend,

PROM is programmable ROM that can be programmed by the user i.e., the programmer.

ROM can only be programmed by the manufacturer and it cannot be modified or altered.

These ROMs are used in specific applications where the order is placed to the manufacturer along with the necessary specifications of the project or application.
