Validating the status of memory operations

A storage device, comprising:

• a plurality of non-volatile memory devices;
• and
• a controller coupled to the plurality of non-volatile memory devices, the controller configured to:
• send a first set of command instructions to a first device of the plurality of non-volatile memory devices, the first set of command instructions including:
• a memory operation command which, when executed, operates on the first device,
• a first status polling command to determine a status of the first device, and
• a second status polling command to determine a status of the first device;
• wherein the first status polling command is sent to the first device after the memory operation command is sent to the first device, and the second status polling command is sent to the first device after receiving a response to the first status polling command that meets predefined completion criteria;
• and
• forgo sending any subsequent set of command instructions to the first device until a response to the second status polling command that meets the predefined completion criteria is received.

A non-transitory computer-readable storage medium, storing one or more programs for execution by a storage device with one or more processors, the one or more programs including instructions for:

• sending a first set of command instructions to a first device of the plurality of non-volatile memory devices, the first set of command instructions including:
• a memory operation command which, when executed, operates on the first device,
• a first status polling command to determine a status of the first device, and
• a second status polling command to determine a status of the first device;
• wherein the first status polling command is sent to the first device after the memory operation command is sent to the first device, and the second status polling command is sent to the first device after receiving a response to the first status polling command that meets predefined completion criteria;
• and
• forgoing sending any subsequent set of command instructions to the first device until a response to the second status polling command that meets the predefined completion criteria is received.
