Transfluxor

From HandWiki

A transfluxor was a specialised type of magnetic core memory 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.[1][2] In addition to binary data, transfluxors could also store analog values, with no need to drive them into core saturation.[3][4]

The technology is described in U.S. patent 3048828.[5]

Transfluxors were used in the ARMA Micro Computer.[1]
