    • A Magnetic Matrix Switch and its Incorporation into Coincident-Current Memory 

      Olsen, Kenneth H. (MIT Digital Computer Laboratory, 1952-06-06)
      The random-access memory is an important element of a high-speed digital computer. This memory must be capable of operating at high speeds with long-time reliability, and should be compact and of low cost. The coincident-current ...

    • The 16 x 16 Metallic-Core Memory Array, Model 1 

      Widrowitz, Bernard (MIT Digital Computer Laboratory, 1952-09-25)
