| Abstract(in English) | This study focuses on a look-up table (LUT) based on a single flux quantum (SFQ) logic circuit. To realize highly-integrated SFQ LUT, we designed a new memory cell, data input of which is performed by applying dc-currents coupled to the cell. We can write the data to the selected memory cell in the 2-D memory cell array by applying both the x- and y-directional dc-currents. The memory cell is an SFQ non-destructive read-out flip-flop (NDRO) with magnetically-coupled data-input structure. Thought data writing and resetting of the designed memory cell are slow, we can implement the highly-integrated LUT using the memory cell because the wiring for the data-input and data-resetting can be drastically simplified compared to the conventional SFQ LUT that used many passive transmission lines(PTL) for data-input and initializing the data stored in the memory cells. We experimentally confirmed the correct operation of designed memory cell with enough bias margin. |
