  • Patent number: 11169739
    Abstract: A memory system may include: a nonvolatile memory device; a volatile memory device to which power is suspended in the sleep mode; and a controller configured to temporarily store internal data in the volatile memory device, the internal data being generated during processing of an operation of the nonvolatile memory device. When a sleep command is received by the memory system from a host, the controller may output the internal data stored in the volatile memory device to the host in response to the sleep command, and then may transfer an acknowledgement for an entry into the sleep mode to the host and enter the sleep mode.

  • Patent number: 9164833
    Abstract: A data storage device includes a nonvolatile memory device; and a controller suitable for controlling an operation of the nonvolatile memory device in response to a request from an external device, wherein the controller comprises a victim block setup unit suitable for setting a victim block for a merge operation based on an error count, which is detected when a read operation of the nonvolatile memory device is performed, and for storing information of the victim block for the merge operation, and wherein the controller converts the victim block into a free memory block during the merge operation and reuses the free memory block to store data.
