Abstract: An electronic system includes: a host; and a storage device configured to exchange data with the host using an interface protocol. The host provides a fault insertion command, including a fault type, a target location, and a fault condition, to the storage device, based on the interface protocol. The storage device performs a fault detection operation, selected based on the fault type among an assert code execution operation, a memory polling operation, an interrupt polling operation, and a latency detection operation, on the target location in response to the fault insertion command, and stores a snapshot of the storage device when the fault condition is detected as a result of performing the fault detection operation. The host obtains the stored snapshot using the interface protocol, and debugs the storage device using the obtained snapshot.

Abstract: A method of operating a storage device with a memory includes partitioning an entire area of a first namespace into at least one area based on a reference size. The partitioning is performed in response to a namespace creating request from a host that includes size information corresponding to the entire area of the first namespace. The method further includes partitioning a logical address space of the memory into a plurality of segments, allocating a first segment of the plurality of segments to a first area of the at least one area, and storing mapping information of the first area and the first segment. A size of the logical address space is greater than a size of a physical storage space of the memory identified by the host.

Abstract: A device controller of a storage device including a non-volatile memory peeks a command from a submission queue, and determines whether the peeked command is executable based on a status of device resources. In response to determining that the command is executable, the device controller fetches the command, allocates the device resources to the fetched command, and executes the command.

Abstract: A host system includes a host device configured to generate a first log, a storage device configured to generate at least one second log, and a shared memory configured to store the first log and to store composite logs corresponding to the first log and the at least one second log. The storage device reads the first log from the shared memory, adds a timestamp and log-type information to the first log and the at least one second log to generate the composite logs, and writes the composite logs to the shared memory.
