RESEARCH ON AUTOMATIC COMPUTER ELECTRONICS Vo1. I. Computer Device and Circuit Research

摘要

This report is one of three volumes describing results of a 13-month applied research program called RACE, Research on Automatic Computer Electronics. The program is a broad-front applied research investigation in the area of discrete-variable technology. The report describes results obtained as well as investigations in progress.nThe computer device and circuit research work (Phase A), which is described in this volume of the report, includes a phenomena survey intended to develop possible new directions for later research. The information is presented both as short descriptions of the various phenomena, and also as summary lists developed from punched-card abstracts. Experiments in the solid-state physics area are described which have resulted in the following devices or designs: (1) a ternary logic element, (2) the design of a ternary threshold element, (3) a cryogenic ternary storage element, (4) the design of a memory array using ternary storage elements, and (5) the design of a variable gain threshold element. The descriptions of the work on ferrite logic include discussion of various single-unit flux-steered ferrite devices, as well as experimental results obtained in performing selected parallel logic operations.
