Method for reducing solid-state device (ssd) open time and system thereof

A system for reducing open time of a Solid-State Drive (SSD), the system comprises:

• at least one controller;
• a volatile memory communicatively coupled with the at least one controller;
• and
• a non-volatile memory communicatively coupled with the at least one controller and the volatile memory;
• wherein the at least one controller is configured to:
• divide a logical-to-physical (L2P) address mapping table of the SSD, stored in the volatile memory, into a plurality of segments;
• create a plurality of journal buffers for the plurality of segments;
• assign one journal buffer of the plurality of journal buffers to each segment of the plurality of segments, wherein each journal buffer of the plurality of journal buffers stores entries representing changes made, during one or more write operations of the SSD, to the assigned segment of the L2P address mapping table;
• recreate, during a power on sequence of the SSD, a portion of the plurality of segments by replaying a first subset of the plurality of journal buffers corresponding to the portion of the plurality of segments, the first subset of the plurality of journal buffers being previously stored in the non-volatile memory;
• send, to a host device, a device-ready signal upon successful recreation of the portion of the plurality of segments;
• and
• recreate, in a background mode, a remaining portion of the plurality of segments by replaying a second subset of the plurality of journal buffers corresponding to the remaining portion of the plurality of segments, the second subset of the plurality of journal buffers being previously stored in the non-volatile memory.

A non-transitory computer-readable storage medium comprising instructions that are executable by a processing device of a solid-state device (SSD), and cause the SSD to:

• divide a logical-to-physical (L2P) address mapping table of the SSD into a plurality of segments;
• create a plurality of journal buffers for the plurality of segments;
• assign one journal buffer of the plurality of journal buffers to each segment of the plurality of segments, wherein each journal buffer of the plurality of journal buffers stores entries representing changes made, during one or more write operations of the SSD, to the assigned segment of the L2P address mapping table;
• recreate, during a power on sequence of the SSD, a portion of the plurality of segments by replaying a first subset of the plurality of journal buffers corresponding to the portion of the plurality of segments;
• send, to a host device, a device-ready signal upon successful recreation of the portion of the plurality of segments;
• and
• recreate, in a background mode, a remaining portion of the plurality of segments by replaying a second subset of the plurality of journal buffers corresponding to the remaining portion of the plurality of segments.
