A Dimond ring was a type of transformer read-only storage, created by T. L. Dimond for Bell Telephone Laboratories in 1945. The Dimond ring consisted of wires fed through transformer cores, which represented binary inputs.
It was used for the No. 5 Crossbar switch, the Bell Laboratories Model 6 computer, and the IBM System/360, for the primary purpose of translating and running code. [1]
Structure
[edit]The basic structure of the Dimond ring was multiple transformer cores in the shape of rings, representing binary inputs. A wire, known as a word line, would pass through or bypass each ring, with a 1 being detected if the wire did pass through a ring, and a 0 if the word line did not pass through a transformer core.
Applications
[edit]Limitations
[edit]As memory size increases as well as the demand for more word lines, more elaborate sensing designs are required to prevent signal noise from interfering with the detection process.
