Computer Memory

Computer Memory by Rona Black

An abstract macro photograph of a Ferrite Memory Core plane from an early IBM mainframe computer. This grid is made up of fine wire threaded through tiny magnetic ferrite rings (cores). Magnetic core memory, a type of random-access memory (RAM), was introduced in 1955 and succeeded in the 1970s by solid-state memory in integrated circuits.

The Museum of Modern Art has three in its permanent collection, but none on display.

  1. The thing about this is I worked on a RADAR that used a ferrite core memory,It had a stupid number of connections on top, that as a new techie, I had to wire wrap into the machine when it needed changing. When did I get old? Things I worked on are now in museums, I don’t know if I can cope with this.

  2. Imagine how big physically this is compared to the little memory flash drives and computer chips of today. Great shot Rona, B&W shows it well.
