This gave way to Mask ROM with the advent of integrated circuits. This was memory made up of discrete semiconductor diodes placed on a specially organized PCB. A Brief History of ROMĮarly "Stored-Program" type computers - such as desk calculators and keyboard interpreters - began using ROM in the form of Diode Matrix ROM.
The BIOS in your PC is stored on a form of ROM. This makes it ideal for things like firmware which need to be "remembered" by the computer, but never actually change. The trade-off for very slow write times - traditionally - is that it's also non-volatile meaning that the data doesn't go away when power is removed from the device. This is because it's very slow - or impossible - to write new data to ROM. Read-Only Memory ( ROM) is a type of computer memory which, generally speaking, is only programmed once (or very occasionally) and then gets read from the rest of the time. That said, if you don't nerd-out on computer history it's probably safe to skip that section.
