| Abstract(in English) | We are developing a Josephson-CMOS hybrid memory, which enables sub-nanosecond access time, in order to overcome a memory bottleneck in single-flux-quantum (SFQ) digital systems. In this study, we improved the robustness of the Josephson-CMOS interface for realizing the complete operation of the 64-kb hybrid memory. One problem in our interface circuits is the interaction between the AC bias current for Josephson latching drivers with the SFQ circuits. We have reduced the interaction by using partially separated ground planes and magnetic-shielding structures for the SFQ circuits. |
