  • Patent number: 11983441
    Abstract: An integrated circuit includes a front-end interface, a back-end interface, a controller, and arbiter circuitry. The front-end interface communicates with a remote host over a front-end fabric. The back-end interface communicates with nonvolatile memory (NVM) subsystems over a back-end fabric. The controller is coupled between the front-end interface and the back-end interface. The controller receives commands from the remote host for the NVM subsystems, and stores the commands in queue pairs associated with the NVM subsystems. The arbiter circuitry receives data for the queue pairs, and selects a command from a first queue pair of the queue pairs based on a comparison of the data to one or more thresholds. The selected command is outputted to one or more of the NVM subsystems.
