    Abstract: A memory request management system may include a memory device and a memory controller. The memory controller may include a read queue, a write queue, an arbitration circuit, a read credit allocation circuit, and a write credit allocation circuit. The read queue and write queue may store corresponding requests from request streams. The arbitration circuit may send requests from the read queue and write queue to the memory device based on locations of addresses indicated by the requests. The read credit allocation circuit may send an indication of an available read credit to a request stream in response to a read request from the request stream being sent from the read queue to the memory device. The write credit allocation circuit may send an indication of an available write credit to a request stream in response to a write request from the request stream being stored at the write queue.

    Abstract: Systems, apparatuses, and methods for addressing bank hotspotting are described. A computing system includes a memory controller with an arbiter for determining how to arbitrate access to one or more memory device(s) for received requests. The arbiter categorizes each request in a manner that helps to ensure fair virtual channel distribution across the banks of the memory device(s). The category system includes bank hotspotting functions to give banks that have more requests more chances to go over banks with fewer requests. The category system is implemented proportionally with more category credits given to banks with higher bank depths within the virtual channel.
