摘要： In a superconducting random access memory according to this invention, drive lines such as a word line and a bit line, and a sense line for accessing a memory cell array are each divided into a plurality of blocks and an in-block signal propagation circuit having a level-logic drive circuit and sense circuit each with high load drive capability is used for signal propagation in each of the blocks. Further, for long-distance signal propagation between the blocks, superconducting passive transmission lines formed by single flux quantum (SFQ) devices and capable of high-speed operation are used. As a result, the high-speed operation as a whole is enabled. It is possible to additionally use splitters or confluence buffers and latch circuits and, further, a binary tree structure may be adopted.

摘要： A high-temperature superconductive device is disclosed, including a ramp-edge junction. The ramp-edge junction includes a first electrode layer (5) that defines the size of the ramp-edge junction and a second electrode layer (6). The width of the second electrode layer (6) is greater than the width of the first electrode layer (5). The first electrode layer (5) and the second electrode layer (6) touch in part, and are separated via a first insulation layer (7) in remaining part. Because the ramp-edge junction includes the first electrode layer (5) and the second electrode layer (6), the inductance of the ramp-edge junction can be reduced with the critical current density Jc being kept at a high level.
