Abstract
A method of communicating with a memory device through a plurality of sub-channels and a control sub-channel includes; setting a first mode or a second mode. In the first mode, writing or reading first data corresponding to a command synchronized to the control sub-channel through the plurality of sub-channels, and in the second mode, independently writing or reading second data and third data respectively corresponding to different commands synchronized to the control sub-channel through the plurality of sub-channels.
Claims20
A storage device comprising:
- a nonvolatile memory including a first region and a second region;
- and
- a controller coupled to the nonvolatile memory,
- wherein in a first mode, the controller is configured to perform a first operation by communicating with the first region of the nonvolatile memory via both a first sub-channel and a second sub-channel,
- in a second mode, the controller is configured to perform a second operation by communicating with the first region of the nonvolatile memory via the first sub-channel and to perform a third operation by communicating with the second region of the nonvolatile memory via the second sub-channel,
- the controller is configured to perform the second operation during a first time period and the third operation during a second time period, and
- a first time period is at least partially overlapped a second time period.

A storage device comprising:
- a nonvolatile memory including a first region and a second region;
- and
- a controller coupled to the nonvolatile memory, and configured to select one of a first mode and a second mode based on a request received from an external device,
- wherein in the first mode, the controller is configured to perform a first operation by communicating with the nonvolatile memory via both a first channel and a second channel,
- in the second mode, the controller is configured to perform a second operation by communicating with the nonvolatile memory via the first channel and to perform a third operation by communicating with the nonvolatile memory via the second channel,
- the controller is configured to perform the second operation and the third operation, and
- the second operation is performed while the third operation is performed.
