meaning of core memory

An early form of computer memory, prevalent from the 1950s to the 1970s, in which information is stored by the magnetic polarity of small ferromagnetic rings (cores) strung on wires.

Early mainframe computers relied heavily on core memory for their primary data storage.

That moment, when I first learned to ride a bike, became a core memory for me, symbolizing independence.

Synonyms: magnetic core memory, ferrite core memory, formative memory, pivotal memory, foundational memory

Etymology: The technical term 'core memory' originated in the context of early digital computers, referring to a type of random-access memory (RAM) that used small magnetic rings, or 'cores', to store data. This technology was dominant from the 1950s to the 1970s. The figurative sense, referring to significant personal memories, gained popular usage more recently, particularly influenced by media such as the 2015 animated film 'Inside Out'.

Cultural Notes: In modern English, 'core memory' is widely used figuratively, especially popularized by media like the animated film 'Inside Out', to describe a foundational and emotionally significant personal experience that contributes to one's identity or worldview. This usage has largely overshadowed its original technical meaning for many general speakers, though the technical term remains valid in historical computing contexts.
