In 1956, however, this problem was solved with the invention of PROM ( Programmable ROM) which allowed developers to program the chips themselves. Unfortunately, Mask ROM was expensive and took a long time to produce because each new program required a brand new device to be manufactured by a foundry. Mask ROM had to be programmed by the manufacturer and was thereafter not alterable. This meant, however, that you couldn't just move a couple of diodes around with a soldering iron and reprogram it. Mask ROM was a lot like Diode Matrix ROM only it was implemented on a much smaller scale. 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 ROMД®arly '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. Introduction to 8051 Programming With AT89C2051 (Guest Starring: Arduino): The 8051 (also known as MCS-51) is an MCU design from the 80's that remains popular today.Before we get into the hookup it's probably a good idea to familiarize ourselves with EEPROM and the history of ROM in general.
