Superconducting/Semiconducting Hybrids and Advance Memory Concepts for Superconducting Electronics
Abstract
The goal of this program is to explore advanced alternatives to the standard approaches to memory in Josephson junction digital electronics. The work includes the physics, circuits and systems aspects of the problem. It is widely recognized that memory is the weak suit of digital superconductive electronics. There are several problems. They are hard to build, particularly at high densities. Their speed is being challenged by leading edge semiconductor memories, albeit at the expense of high power dissipation. They are susceptible to trapped flux, which is both random in space and likely varying in time. All the current approaches to memory are based on the concept of storage of magnetic flux in a superconducting ring first proposed over 25 years ago by Anacker. Basically, there have been no new ideas in superconductive memory since that time
