Read and write enhancements for arrays of superconducting memory cells

Abstract

A method for applying and propagating superconducting signals in a superconducting memory circuit is provided. The memory circuit includes passive cells and at least one power-signal propagation circuit. The method includes: configuring the memory circuit such that the passive cells are arranged into sets, each set of passive cells having associated therewith at least one common superconducting wire interconnecting a subset of the passive cells; configuring the memory circuit such that an input of the power-signal propagation circuit is coupled to a preceding set of passive cells via a first superconducting wire, and an output of the power-signal propagation circuit is coupled to a subsequent set of passive cells via a second superconducting wire; applying a first superconducting signal to the first superconducting wire; and applying a second superconducting signal to the second superconducting wire in response to applying the first superconducting signal to the first superconducting wire.
