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

Abstract

This report contains a history and some technical details of the development of our first two-dimensional, coincident-current, magnetic-core memory for binary digital computer use. The work described herein received its impetus from the research of two men: Jay W. Forrester, who proposed the coincident-current selection scheme, and William N. Papian, who systematized the pulse-testing of magnetic cores and constructed an experimental 4-cell memory.
