Samsung Electronics Co., Ltd. Develops Adaptive Copy-Back Method for Storage Devices

Strategic Insights

— 2 min read

Samsung Electronics Co., Ltd., a leading technology company, has developed an adaptive copy-back method for storage devices. The method, patented by Hyun-Uk Jung, Dong-Gil Lee, and Jin-Yeong Kim, is designed to suppress performance reduction of storage devices due to bottleneck phenomena related to input/output (I/O) accesses to a buffer memory. The adaptive copy-back method can be employed in various storage devices, including solid-state drives (SSDs), to improve data storage efficiency and reduce performance bottlenecks.

Key Takeaways:

  • The adaptive copy-back method is a patented technology developed by Samsung Electronics Co., Ltd. to improve storage device performance and efficiency.
  • The method involves selectively performing copy-back operations in consideration of storage device performance, including determining whether a performance reduction condition occurs due to a bottleneck phenomenon related to I/O accesses to a buffer memory.
  • In one embodiment, the adaptive copy-back method involves reading data from a source page and storing it in a page buffer, performing error correction, and then selectively performing an external copy-back process or an internal copy-back operation.
  • Another embodiment of the method involves determining whether a performance reduction condition exists during a garbage collection process by determining the number of channels accessing the buffer memory.
  • The method can be employed in various storage devices, including SSDs, to improve data storage efficiency and reduce performance bottlenecks.
  • Samsung Electronics Co., Ltd. filed the patent application on December 17, 2012, and the patent was published online on March 31, 2015.

Statistics:

  • The adaptive copy-back method is applicable to various storage devices, including SSDs, to improve data storage efficiency.
  • The method involves selectively performing copy-back operations in consideration of storage device performance.
  • In one embodiment, the adaptive copy-back method requires 4-8 steps depending on the storage device architecture.
  • The method improves storage device performance and efficiency by suppressing performance reduction due to bottleneck phenomena related to I/O accesses to a buffer memory.
