Switch for Register Selection in a Magnetic-Core Memory

Abstract

The practicability of the magnetic core as the basic storage element in a high-speed digital computer has been established with the installation and successful operation of the banks of core storage in the WWI computer. It has long been realized that the basic function of a memory system, storage and switching, can be performed in many different ways using cores. Some techniques for performing these functions, especially selection, are explored and analyzed in this paper. The author is grateful to Mr. D. R. Brown for undertaking the supervision of this thesis; to Mr. W. N. Papian for many helpful suggestions; to Mr Jay. W Forrester; and to the Staff of Division 6, Lincoln Laboratory, without whose aid this thesis work would have been impossible. Because it presents information of general interest, this thesis report, which has had only very limited distribution, is being issued as a Division 6 R-series report.
