Abstract
Provided is a storage device capable of increasing its life cycle and operating method thereof. The storage device includes a nonvolatile memory device that stores data and a controller that controls the nonvolatile memory device. The controller receive can modify a write time-out value of the nonvolatile memory device in accordance with predetermined conditions, such as request from a host or exceeding of a predefined life cycle.
Claims30
A storage device, comprising:
- a nonvolatile memory device that stores data;
- and
- a controller that controls the nonvolatile memory device,
- wherein the controller receives a request from a host for write time-out value modification and modifies a write time-out value of the nonvolatile memory device.
A storage device, comprising:
- a nonvolatile memory device that stores data;
- and
- a controller that controls the nonvolatile memory device,
- wherein, when the nonvolatile memory device is used in excess of a predefined life cycle, the controller modifies a write time-out value of the nonvolatile memory device.
A storage device, comprising:
- a host interface that receives a request for write time-out value modification from a host;
- and
- a processor that modifies the write time-out value of the nonvolatile memory device in accordance with the request for the write time-out value modification.
A host device that controls a storage device including a nonvolatile memory device, the host device comprising:
- a host processor that determines whether to modify a write time-out value of the nonvolatile memory device or not;
- and
- an interface module connected to the host processor and makes a request for the write time-out value modification to the storage device according to the determination result.
An operating method of a storage device, comprising:
- receiving a request for write time-out value modification from a host;
- modifying the write time-out value of the nonvolatile memory device in accordance with the request for the write time-out value modification;
- and
- providing a set response signal indicating that the write time-out value is modified.
A storage device, comprising:
- a nonvolatile memory device that stores data;
- and
- a controller that controls the nonvolatile memory device,
- wherein the controller modifies a write time-out value of the nonvolatile memory device and sends a notification to a host that modification of the write time-out value of the nonvolatile memory device has occurred.
