Claim 15:
16. A method of managing metadata, comprising:
receiving, by a processing circuit, a data request command over a host interface to access non-volatile memory, the data request command including data associated with the data request command, first metadata, and second metadata;
determining, by the processing circuit, the second metadata included with the data request command;
based on a configuration received over a first interface different from the host interface, logging, by the processing circuit, the second metadata in one or more log pages in protected memory;
receiving, by the processing circuit, a separate command over the first interface; and
retrieving, by the processing circuit, the second metadata from the one or more log pages in response to the separate command,
wherein the first metadata is associated with the data, and processed according to the data request command, and
wherein the second metadata is user-defined metadata included with the data request command, is separately stored from the data and the first metadata, and is processed according to the separate command.
