This magnetic read-only memory (ROM), contrary to ordinary coincident-current magnetic core memories (used for RAM), uses the ferrite cores as transformers. If you look at the picture above ...

Early computer memories stored data in the residual magnetic fields of ferrite cores, which were assembled into arrays of core memory. Their powders are used in the coatings of magnetic recording ...

The tour continues on to ferrite core memory such as that used on mainframes, minicomputers, and even the Apollo Guidance Computer. Each type is examined for its strengths and weaknesses and its ...

In computer memory applications, the forward direction is 0 and ... test measurements and methods, and ferrite materials. Magnetic cores that are sold in Europe bear the CE mark to indicate compliance ...
