Abstract: Methods, systems, and computer readable media for submission queue pointer management are disclosed. One method is implemented in a data storage device including a controller and a memory. The method includes fetching a plurality of commands from a submission queue. The method further includes parsing at least one of the commands. The method further includes, in response to successful parsing of at least one of the commands and prior to executing all of the commands, notifying a host to advance a head entry pointer for the submission queue by a number of entries corresponding to a number of the commands successfully parsed.

Abstract: A data storage system includes a storage medium including plurality of memory cells, a storage controller in communication with the storage medium, an electrical interface circuitry configured to pass data via a channel disposed between the storage medium and the storage controller; and voltage training circuitry configured to train a high-level output voltage (VOH) for each of a plurality of data lines of the channel. Training the VOH includes, for each of the plurality of data lines of the channel, calibrating a pull-up driver of the storage controller against an on-die termination circuit of the storage medium, calibrating a pull-down driver of the storage controller against the pull-up driver of the storage controller, and calibrating an on-die termination circuit of the storage controller against a pull-up driver of the storage medium.
