The reason they have that name is that magnetic core memory was the primary storage for computers back in the old days and many of us still refer to a computer’s main memory as “core.” ...

The first non-volatile memory that was widely used. Core storage held magnetic charges in tiny ferrite cores, and the direction of the flux determined the 0 or 1. Developed in the late 1940s by Jay W.

What did early computers use for fast read/write storage? Surprisingly, drum memory–a similar ... the donut (or core) could have a clockwise magnetic field or a counterclockwise field.

indicating the need for highly efficient data storage solutions. Researchers have now developed a voltage-controlled magnetic memory as an energy-efficient alternative. The research led by ...
