摘要： A word line driver circuit coupled to a memory circuit word line includes pull-up, pull-up clamp, pull-down and pull-down clamp transistors, each having a source, a drain and a gate. For the pull-up transistor, the source is coupled to a first power supply, and the gate to a pull-up control signal. For the pull-up clamp transistor, the source is coupled to the drain of the pull-up transistor, the drain to the word line, and the gate to a pull-up clamp gate signal. For the pull-down transistor, the source is coupled to a second power supply, and the gate to a pull-down control signal. For the pull-down clamp transistor, the source is coupled to the drain of the pull-down transistor, the drain to the word line, and the gate to a pull-down clamp gate signal. The word line is coupled to one or more DRAM cells. Source to drain voltage magnitudes of the pull-up and pull-down transistors are less than a voltage between the first and second power supplies.

摘要： A superconducting memory circuit for applying and propagating superconducting signals through a plurality of superconducting wires in the memory circuit is provided. The memory circuit includes multiple passive cells arranged in a plurality of sets. Each set of passive cells has associated therewith at least one common superconducting wire interconnecting a subset of the passive cells in the set of passive cells. The memory circuit further including at least one power-signal propagation circuit, an input of the power-signal propagation circuit being coupled with a preceding set of passive cells via a first superconducting wire, and an output of the power-signal propagation circuit being coupled with a subsequent set of passive cells via a second superconducting wire. Upon application of a first superconducting signal to the first superconducting wire, the power-signal propagation circuit applies a second superconducting signal to the second superconducting wire.

摘要： Superconducting logic arrays (SLAs) and field-programmable gate arrays (FPGAs) that are based on Josephson transmission lines (JTLs) accommodate reciprocal quantum logic (RQL) compliant binary input signals and provide RQL-compliant output signals that are evaluations of generalized logic functions. Each JTL-based superconducting FPGA (JTLBSFPGA) incorporates multiple JTL-based SLAs (JTLBSLAs) connected together. Each JTLBSLA includes an array of software-programmable and/or mask-programmed logic cells that output products of inputs and cell states, such that the JTLBSLAs output evaluations of sum-of-products functions. New JTLBSLA logic cells are described, including some that provide programmable cell states via magnetic Josephson junctions (MJJs). JTLBSFPGAs provide area efficiency and clock speed advantages over CMOS FPGAs. Unlike SLAs based on Josephson magnetic random access memory (JMRAM), JTLBSLAs do not require word line drivers, flux pumps, or sense amplifiers. Because JTLBSLAs and JTLBSFPGAs are RQL-compliant, they can also include RQL gates connected within or between them, without signal conversion circuitry.
