Conventional computer memory is known as “semiconductor memory” and was invented in 1968. It’s based on technology known as the “semiconductor” which was invented in 1947. Many semiconductors grouped together is called an “integrated circuit”, more commonly known as a “computer chip”. Examples of semiconductor memory include ROM, RAM and flash memory.

A big advantage of computer RAM (main memory) is price; ram is inexpensive. The main disadvantage of RAM is volatility; when you turn your computer off, the contents of RAM are lost. Molecular memory is the name of a technology that uses organic molecules to store binary data.
