1. A method for performing non-data transfer access commands, the method comprising:

  • receiving information from a non-volatile memory (“

    NVM”

    ) indicating that the NVM supports a flag bit command format;

    saving access commands in a queue stored in volatile memory, wherein at least a subset of the access commands are non-data transfer access commands, and wherein each non-data transfer access command comprises a flag bit that is set to indicate one of lack of data association and that no data transfer is desired; and

    dispatching each of the access commands in the queue, wherein dispatches associated with the non-data transfer access commands have zero latencies.
