Outline of Final Research Achievements

The research on large-capacity, low-power shift-register-based memories was done toward realization of high-performance computing system based on the single-flux-quantum logic technology. A compact, low-power shift-register cell was newly developed. The low-voltage circuit design technique was established, which is applicable to not only the shift-register-based memories but also to general circuits, achieving high energy efficiency. These results supports the feasibility of a few kilobits, ultra-high-speed memories with reasonable density and power consumption.
