Which memory type is non-volatile and can be burnt to set its contents permanently?

Explanation:
Non-volatile memory that can be permanently set by a one-time programming step is ROM. It retains data without power, unlike RAM, cache, or registers which lose their contents when power is removed. Some ROM variants are programmed by "burning" a chip (PROM), fixing the data permanently so it cannot be changed afterward. That permanence is why ROM is the best choice for storage of fixed firmware.
