Abstract: Methods, systems, and computer-readable storage media for a storage device to, upon receiving a command from a computing host, determine whether or not the command includes location information targeting a particular portion of a NVM of the storage device, the location information having been retrieved by the computing host from a shadow map and included with the command. Upon determining that the command includes location information, the command is processed by the storage device using the included location information. Upon determining that the command does not include location information, the storage device determines the particular portion of the NVM targeted by the command based on a map stored in a memory of the storage device before processing the command.

Abstract: An apparatus includes a memory and a controller. The memory may be configured to store data. The controller may have a host interface circuit connectable to a host. The controller may be configured to process a plurality of input/output requests to read/write to/from the memory, compute a first bandwidth consumed by the controller while servicing the memory with one or more tasks hidden from the host, compute a second bandwidth of the memory that is available to the host through the host interface circuit based on the first bandwidth consumed by the controller, receive a hypothetical consumption of additional bandwidth by the host, update the second bandwidth based on the hypothetical consumption, and report the second bandwidth as updated to the host through the host interface circuit.

Abstract: Methods, systems and computer-readable storage media for receiving, via an external interface of a storage device, a command from a computing host, the command including at least one non-standard command modifier, executing the command according to a particular non-standard command modifier, storing an indication of the particular non-standard command modifier in an entry of a map associated with a logical block address of the command, and storing a shadow copy of the map in a memory of the computing host.

Abstract: An apparatus includes a memory and a controller. The memory includes a plurality of memory devices. Each memory device has a plurality of page types. The plurality of page types are classified based on error rate variations. The controller may be configured to write user data and error-correction data to the memory. The user data and the error-correction data are organized as a super-page. The super-page includes a plurality of sub-pages. The plurality of sub-pages are written across the plurality of memory devices such that the plurality of sub-pages are stored using more than one of the plurality of page types.
