Data Storage Device and Method for Device-Initiated Hibernation - A simplified explanation of the abstract

This abstract first appeared for US patent application 17752305 titled 'Data Storage Device and Method for Device-Initiated Hibernation

Simplified Explanation

The patent application describes a data storage device and method for device-initiated hibernation.

  • The data storage device includes a non-volatile memory and a controller.
  • During the set-up phase of a hibernation process, the controller receives write commands from a host, which indicate the current state of the host's volatile memory.
  • These write commands are stored in a queue and not executed immediately.
  • The controller then receives a trigger from the host to start the execution phase of the hibernation process.
  • In response to the trigger, the controller executes the stored write commands, saving the current state of the host's volatile memory in the non-volatile memory of the data storage device.
  • This allows for efficient hibernation of the host system and quick resumption of operations when needed.
  • The invention can be used alone or in combination with other embodiments.


Original Abstract Submitted

A data storage device and method for device-initiated hibernation are provided. In one embodiment, the data storage device comprises a non-volatile memory and a controller. The controller is configured to: receive, from a host during a set-up phase of a hibernation process, a plurality of write commands with a current state of a volatile memory in the host; store the plurality of write commands in a queue, wherein the plurality of write commands are not executed during the set-up phase of the hibernation process; receive a trigger from the host to perform an execution phase of the hibernation process; and in response to receiving the trigger, execute the plurality of write commands to store the current state of the host's volatile memory in the non-volatile memory of the data storage device. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
