Samsung patents method to protect data in storage devices under heavy read loads

Samsung has filed a patent for a method that manages storage wear by moving data from frequently read locations to a temporary buffer. This process helps prevent data loss when a storage device is subjected to intensive read workloads.

Why it mattersThis is a routine improvement to how storage devices handle wear and tear, ensuring data reliability during heavy usage.

In the filing’s own words

A method may include: reading a first Logical Block Addresses (LBA) from a host read buffer; identifying a first read disturbance in the first LBA; copying first data associated with the first LBA to a Garbage Collector (GC) buffer pool, based on the identifying the first read disturbance; reading a second LBA from the host read buffer; identifying a second read disturbance in the second LBA; copying second data associated with the second LBA to the GC buffer pool, based on the identifying the second read disturbance; generating a reclaim queue including the first LBA and the second LBA; identifying at least part of the first data and the second data to be written from the GC buffer pool to a GC destination block; and writing the at least part of the first data and the second data to the GC destination block.

What exactly they claim (claim 1)

1. A method of managing read disturbance in a storage device, the method comprising: reading a first Logical Block Addresses (LBA) from a host read buffer; identifying a first read disturbance in the first LBA; copying first data associated with the first LBA to a Garbage Collector (GC) buffer pool, based on the identifying the first read disturbance; reading a second LBA from the host read buffer; identifying a second read disturbance in the second LBA; copying second data associated with the second LBA to the GC buffer pool, based on the identifying the second read disturbance; generating a reclaim queue comprising the first LBA and the second LBA; identifying at least part of the first data and the second data to be written from the GC buffer pool to a GC destination block; and writing the at least part of the first data and the second data to the GC destination block, based on the reclaim queue, to avoid the at least part of the first data and the second data being lost.
