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