NAND Dropped Command Detection and Recovery

A storage device, comprising:

• a memory;
• and
• a controller coupled to the memory and configured to:
• receive, from a host device, a data command;
• query a die status from the memory at a time after a first time at which the data command is expected to begin execution and prior to a second time at which the data command is expected to complete execution;
• and
• detect whether the data command is dropped based on the die status.

A storage device, comprising:

• a memory;
• and
• a controller coupled to the memory and configured to:
• issue a storage device command to a particular die in the memory based on a host command;
• and
• perform a dropped command detection (DCD) status query on the particular die within a time period after the storage device command is issued, the DCD status query indicating whether the storage device command is dropped, the time period being bounded by a first time at which the storage device command is expected to begin execution and a second time at which the storage device command is expected to complete execution.
