Dynamic per-bank and all-bank refresh

A method, comprising:

• executing, by one or more computing resources, one or more applications;
• generating, by the one or more computing resources, memory access requests for data stored in a memory device comprising a plurality of ranks, each rank comprising a plurality of banks;
• receiving, by a memory controller, the memory access requests;
• receiving, by the memory controller, information identifying the one or more applications;
• predicting, by the memory controller, a first latency between accesses of a given rank of the plurality of ranks based at least upon the received information;
• and
• in response to receiving an indication to start a refresh interval for the given rank:
• selecting, by the memory controller, one or more refresh operations based upon the first latency;
• and
• performing, by the memory controller, the selected one or more refresh operations on the given rank.

A memory controller comprising:

• a first interface for receiving memory access requests generated by one or more computing resources executing one or more applications;
• a second interface for sending the memory access requests to a memory device comprising a plurality of ranks, each rank comprising a plurality of banks;
• and
• control logic, wherein the control logic is configured to:
• receive information identifying the one or more applications;
• predict a first latency between accesses of a given rank of the plurality of ranks based at least upon the received information;
• and
• in response to receiving an indication to start a refresh interval for the given rank:
• select one or more refresh operations based upon the first latency;
• and
• perform the selected one or more refresh operations on the given rank.
