Timing control in a quantum memory system

A method for reading and writing data in a quantum memory system, the method comprising:

• receiving a memory request signal associated with a selected row of an array of quantum memory cells arranged in rows and columns;
• generating one of write currents and read currents from a plurality of flux pumps, the one of the write currents and the read currents being provided to the array of quantum memory cells to one of write data to and read data from the selected row, respectively, in response to the memory request signal;
• storing an address associated with the selected row in a busy address register based on a predetermined time associated with application of the one of the write currents and the read currents and based on a predetermined time associated with recharging flux associated with the plurality of flux pumps;
• and
• selectively prohibiting access to at least one of the selected row and columns associated with the selected row via the memory request signal until expiration of the predetermined time.

A memory system comprising:

• a memory controller configured to generate memory request signals in response to commands from a central processing unit (CPU);
• and
• a quantum memory system comprising:
• a plurality of quantum memory cells arranged in an array of rows and columns, each of the plurality of quantum memory cells being configured to store a binary logic state in response to write currents in a write operation and configured to provide an indication of the binary logic state in response to read currents in a read operation;
• and
• an array controller comprising a plurality of flux pumps configured to provide the write currents and the read currents with respect to the rows and columns, the array controller being configured to control timing associated with the write operation and the read operation in response to memory request signals based on a predetermined time associated with application of the write currents and the read currents and associated with recharging flux associated with the plurality of flux pumps.
