PROACTIVE LOSS NOTIFICATION AND HANDLING IN DATA STORAGE DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17752771 titled 'PROACTIVE LOSS NOTIFICATION AND HANDLING IN DATA STORAGE DEVICES

Simplified Explanation

The patent application describes devices, systems, and methods for proactive data loss notification and handling in data storage devices.

  • The data storage device includes a memory and a controller.
  • The controller has a processor and controller memory.
  • The controller memory stores instructions for the controller to perform certain actions.
  • During an internal data movement process, if an uncorrectable error correction code (UECC) is detected, the controller modifies a metadata field associated with the corresponding logical block address.
  • The host device is informed about the UECC.
  • The controller then determines whether data stored in adjacent regions to the logical block address is lost.
  • This technology aims to proactively notify and handle data loss situations in data storage devices.


Original Abstract Submitted

Devices, systems, and methods with proactive data loss notification and handling. A data storage device includes a memory and a controller. The controller includes a processor and controller memory. The controller memory stores a set of instructions that, when executed by the processor, instruct the controller to: detect an uncorrectable error correction code (UECC) during an internal data movement process of the storage device memory, modify a metadata field associated with a logical block address corresponding to the UECC, inform a host device about the UECC, and determine whether data stored in at least one adjacent region to the logical block address is lost.
