Memory bank hotspotting

A method, comprising:

• forwarding, by arbitration circuitry, memory requests to individual banks of a plurality of banks of a memory device that have a credit available;
• and
• performing, by allocation circuitry, an iteration of a plurality of iterations, comprising:
• determining, for a bank of the plurality of banks, a total credit comprising a sum of a previous fractional credit and a given credit, wherein the previous fractional credit is maintained from a previous iteration of the plurality of iterations, and wherein the total credit comprises one or more whole credits and a current fractional credit different from the previous fractional credit;
• granting the one or more whole credits to the bank for arbitration of memory access requests;
• and
• maintaining the current fractional credit for the bank as an input to a subsequent iteration of the plurality of iterations.

A system, comprising:

• a memory device comprising a plurality of banks;
• and
• a memory controller configured to:
• forward memory requests to individual banks of the plurality of banks that have a credit available;
• and
• perform, for an iteration of a plurality of iterations:
• determine, for a bank of the plurality of banks, a total credit comprising a sum of a previous fractional credit and a given credit, wherein the previous fractional credit is maintained from a previous iteration of the plurality of iterations, and wherein the total credit comprises one or more whole credits and a current fractional credit different from the previous fractional credit;
• grant the one or more whole credits to the bank for arbitration of memory access requests;
• and
• maintain the current fractional credit for the bank as an input to a subsequent iteration of the plurality of iterations.
