Abstract
According to one embodiment, a memory system includes a nonvolatile memory (NVM) and a controller. The controller communicates with an external device via virtual channels (VC) defined in PCI Express Base Specification (PCIe). The external device communicates with the NVM of the memory system per NVM Express Base Specification (NVMe). The controller manages a set of priority relation information (PRI), which maps each priority of Weighted Round Robin with Urgent Priority Class Arbitration mechanism defined in NVMe, to a specific VC. Using the PRI, the controller ensures that the same VC is used throughout the command execution transactions. Quality of Service of communication between the external device and the memory system can thus be improved.
