Memory Chip Programmed During Manufacturing Process
ROM (Rean Only Memory) is programmed during the manufactured process. To write data onto a PROM chip, you need a special device called a PROM programmer or PROM burner.
Read only memory refers to memory that is hard-wired, such as diode matrix and the later mask ROM. ROM contains the programming that allow your computer to be “booted up” or regenerated each time you turn it on. There is many ROM chips on the motherboard and some on Expansion board.
Other type of non-volatile memory:
- Prgrammable Read Only Memory (PROM)
- Electrically Programmable Read Only Memory (EPROM)
- Electrically Erasable Programmable Read Only Memory (EEPROM)
- Electrically Alterable Read Only Memory (EAROM)
