Abstract
A storage device is provided which includes a nonvolatile memory device and a controller configured to write meta information, indicating that a transfer of unit data is completed, in a buffer memory when the unit data is transferred to the buffer memory from the nonvolatile memory device.
Claims20
A reading method for a nonvolatile storage device including a memory controller and at least one nonvolatile memory device, the method comprising:
- reading a page data from the at least one nonvolatile memory device in response to a read request from a host, the page data including a plurality of data units;
- storing the plurality of data units included in the read page data into a buffer memory;
- and
- when a part of the plurality of data units is stored into the buffer memory, starting to transmit the part of the plurality of data units stored into the buffer memory to the host before the storing is completed.
A memory system comprising:
- a nonvolatile memory device configured to store a page data including a plurality of data units;
- a memory controller configured to read the page data from the nonvolatile memory device in response to a read request from a host;
- and
- a buffer memory configured to receive the plurality of data units included in the read page data from the memory controller to temporally store the plurality of data units,
- wherein when a part of the plurality of data units is stored in the buffer memory, the memory controller is configured to start to transmit the part of the plurality of data units to the host before all of the plurality of data units are stored in the buffer memory.
A reading method of a memory system including a nonvolatile memory device and a memory controller configured to control the nonvolatile memory device, the method comprising:
- transmitting, at the nonvolatile memory device, a page data stored in the nonvolatile memory to the memory controller under a control of the memory controller, the page data including a plurality of data units;
- storing, at the memory controller, the plurality of data units into a buffer memory connected to the memory controller;
- and
- when a part of the plurality of data units is stored in the buffer memory, starting to transmit, at the memory controller, the part of the plurality of data units to a host before the storing is completed.
