1958
Before the integrated circuit, a magnetic core plane, a series of layered wire grids, was used for computer memory. Magnetic core plane memory was considered an improvement over other methods at the time because it could enable a computer to retain information to be retrieved later, even if it was completely turned off. This is an IBM magnetic core plane from 1958.
