PRE-VALIDATION OF BLOCKS FOR GARBAGE COLLECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18664178 titled 'PRE-VALIDATION OF BLOCKS FOR GARBAGE COLLECTION

The abstract of the patent application describes a data storage device that includes a memory device and a controller. The controller is responsible for selecting a source block, reading metadata associated with the source block, and comparing it to a logical block address to physical block address (L2P) table. It then determines if the flash management unit (FMU) of the source block is valid and adds a new entry associated with the FMU into a valid FMU buffer when the FMU is determined to be valid. The controller also determines when the source block has been fully validated and selects the next source block based on a valid counter, which corresponds to the amount of valid data of the next source block.

The controller selects a source block and reads metadata associated with it.
It compares the metadata to a logical block address to physical block address (L2P) table.
The controller determines the validity of the flash management unit (FMU) of the source block.
When the FMU is valid, a new entry associated with the FMU is added to a valid FMU buffer.
The controller selects the next source block based on a valid counter, which represents the amount of valid data of the next source block.

Potential Applications: - This technology can be used in solid-state drives (SSDs) to improve data storage efficiency. - It can be applied in cloud storage systems to enhance data management processes.

Original Abstract Submitted

A data storage device includes a memory device and a controller. The controller is configured to select a source block, read metadata associated with the source block and compare to a logical block address to physical block address (L2P) table, determine if a flash management unit (FMU) of the source block is valid, and add a new entry associated with the FMU into a valid FMU buffer when the FMU of the source block is determined to be valid. The controller is further configured to determine that the source block has been fully validated and select a next source block based on a valid counter. The valid counter corresponds to an amount of valid data of the next source block.
