Magnetic-core memory was the predominant form of random-access computer memory for 20 years between about 1955 and 1975. Such memory is often just called core memory, or, informally, core. Core memory uses toroids (rings) of a hard magnetic material (usually a semi-hard ferrite) as transformer cores, where each wire threaded through the core serves as a transformer winding. Three or four wires pass through each core.
The term "core" comes from conventional transformers whose windings surround a magnetic core.In core memory the wires pass once through any given core—they are single-turn devices. The magnetic material for a core memory requires a high degree of magnetic remanance, the ability to stay highly magnetized, and a low coercitivity so that less energy is required to change the magnetization

Core memory was a common form of random access memory (RAM) from the mid-1950s to the mid-'70s, and It was developed at MIT in 1951. The memory made use of magnetic rings called cores that had wires passing through them for selecting and detecting the contents of the cores. With the introduction of memory based on semiconductor technology,

magnetic core memory The earliest form of computerised data storage, in which each bit of information was represented by a change in the direction (clock- or counterclockwise) of a magnetic field. Magnetic core memory was replaced by semiconductors, which are several orders of magnitude more powerful.
Magnetic core memory was developed in the late 1940s and 1950s, and remained the primary way that early computers read, wrote and stored data until RAM came along in the 1970s. This tutorial illustrates how it worked. The set up looks a little bit like chocolate doughnuts strung through a chain link fence. While not as tasty, it is a good bit more ingenious. There are a few basic principles of

A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, magnetic recording heads, and magnetic assemblies.It is made of ferromagnetic metal such as iron, or ferrimagnetic compounds such as ferrites.
Magnetic Core MemoryTiny donuts made of magnetic material strung on wires into an array: the idea revolutionized computer memory. Each donut was a bit, magnetized one way for “zero,” and the other way for “one.” The wires could both detect and change the magnetization. In 1953, MIT’s Whirlwind became the first computer to use this technology.Core memory swiftly swept away competing

I have a surplus core memory board that provided 16k words (16-bit) of memory, which I bought off eBay a few years ago. It was manufactured by General Automation Inc, probably in 1977. It comprises 2 boards stacked together. The first contains all the interface logic and drivers, and the second contains the magnetic cores. The cores are small. Really small.
One such example is magnetic core memory. As one of the first stages of random access computer memory, it features tiny, circular ceramic structures (known as cores), all of which contain data and are linked by a network of wires. This storage system is commonly referred to as "core." Core memory owes its existence to two American physicists who emigrated from China. Way-Dong Woo and An Wang
Magnetic memory definition is the deviation of a body from normal behavior under magnetization due to its previous magnetic history.
