  • Patent number: 10871915
    Abstract: A data processing system and a method of operating the same may include a host system and a memory system. The host system may include a host memory and a host controller, and the memory system may include a memory controller and a nonvolatile memory device. The memory controller may include a data attribute determination circuit and a memory selection circuit. The data attribute determination circuit may be configured to determine an attribute of write data received from the host controller. The memory selection circuit may be configured to select, based on the determined attribute of the write data, any one of the host memory and the nonvolatile memory device as a location where the write data is to be stored.
