Abstract
An event notification method of a storage device includes detecting an event in the storage device, writing an asynchronous event information entry corresponding to the event in a completion queue of a host, and transmitting an interrupt corresponding to a transmission of the asynchronous event information entry to the host. The asynchronous event information entry is provided to the host regardless of reception of an asynchronous event request command from the host.
Claims20
An event notification method of a storage device comprising:
- detecting an event in the storage device by a storage controller included in the storage device;
- writing an asynchronous event information entry corresponding to the detected event in a completion queue of a host;
- and
- transmitting an interrupt corresponding to a transmission of the asynchronous event information entry from the storage device to the host,
- wherein the asynchronous event information entry is provided by the storage device to the host regardless of whether or not an asynchronous event request command has been received from the host.

A storage device comprising:
- a nonvolatile memory device;
- and
- a storage controller configured to control the nonvolatile memory device, detect an event in the storage device and write an asynchronous event information entry corresponding to the detected event into a completion queue of a host regardless of whether or not an asynchronous event request command has been received from the host.
A storage device comprising:
- a nonvolatile memory device;
- and
- a storage controller configured to access the nonvolatile memory device responsive to commands from a host, detect occurrence of an event in the storage device, generate an asynchronous event information entry corresponding to the detected event, write the asynchronous event information entry in a completion queue of the host, and thereafter transmit an interrupt to the host,
- wherein the storage controller is configured to detect the event independently without direction from the host.
