      The coincident-current magnetic-core memory was suggested in 1949 by Jay W. Forrester as a reliable, random-access storage medium. Development of the first working memory of this type, for the Memory Test Computer at M.I.T., ...

    • High Speed Core Driver 

      Bradspies, S. (Lincoln Laboratory - Division 6, 1954-10-21)
      A high-speed core driver has been developed. The circuit consists of two pulse amplifiers, a slave flip-flop, a buffer amplifier (which has very rapid rise and fall times), and a current amplifier (Fig. 1). The rise and ...
