A transfluxor was a specialised type of
magnetic core memory
In computing, magnetic-core memory is a form of random-access memory. It predominated for roughly 20 years between 1955 and 1975, and is often just called core memory, or, informally, core.
Core memory uses toroids (rings) of a hard magneti ...
element in which each core had two holes, one for writing and another for reading. It had the unusual property that a core's state could be read without erasing it.
In addition to binary data, transfluxors could also store analog values, with no need to drive them into core saturation.
The technology is described in U.S. patent 3048828.
Transfluxors were used in the
ARMA Micro Computer.
