Superconducting bi-directional current driver

A method for providing a superconducting current through a bidirectional current load in a first direction or a second direction, the method comprising:

• generating an input current via a current source;
• providing a first activation signal to a respective first direction superconducting latch to activate the first direction superconducting latch to provide a current path for the input current from the current source through a second direction superconducting latch and through the bidirectional current load in the second direction;
• and
• providing a second activation signal to the respective second direction superconducting latch to activate the second direction superconducting latch to provide a current path for the input current from the current source through the first direction superconducting latch and through the bidirectional current load in the first direction.

A superconducting bidirectional memory write current driver comprising:

• a current source configured to generate an input current;
• a write line associated with at least one of a row or a column of a memory array, the write line being configured to write a first memory state of at least one memory cell of the respective at least one of the row or the column based on the input current being provided through the write line in a first direction and to write a second memory state of the at least one memory cell of the respective at least one of the row or the column based on the input current being provided through the write line in a second direction opposite the first direction;
• a superconducting bidirectional current driver comprising:
• a first direction superconducting latch that is activated in response to a first activation signal;
• and
• a second direction superconducting latch that is activated in response to a second activation signal,
• wherein the second direction superconducting latch is activated to provide a first current path of the input current through the first direction superconducting latch and through the write line in the first direction,
• wherein the first direction superconducting latch is activated to provide a second current path of the input current through the second direction superconducting latch and through the write line in the second direction.
