INDEPENDENT FLASH TRANSLATION LAYER TABLES FOR MEMORY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18383746 titled 'INDEPENDENT FLASH TRANSLATION LAYER TABLES FOR MEMORY

Simplified Explanation

The memory sub-system described in the patent application includes multiple flash translation layer (FTL) tables that provide services such as translating logical addresses to physical addresses. If one FTL table is corrupted, another FTL table can be used to maintain read-write access to the memory sub-system, improving reliability.

  • Memory sub-system with multiple FTL tables:
   * Provides translation of logical addresses to physical addresses.
   * Allows for continued read-write access in case of FTL table corruption.
   * Improves reliability of the memory sub-system.

Potential Applications

The technology described in the patent application could be applied in:

  • Solid-state drives (SSDs)
  • Embedded systems
  • Data centers

Problems Solved

The technology addresses the following issues:

  • FTL table corruption
  • Data loss due to memory sub-system failures

Benefits

The benefits of this technology include:

  • Improved reliability of memory sub-systems
  • Enhanced data storage and retrieval efficiency

Potential Commercial Applications

A potential commercial application for this technology could be in:

  • Enterprise storage solutions

Possible Prior Art

One possible prior art for this technology is the use of multiple FTL tables in memory sub-systems to improve reliability and data access.

Unanswered Questions

How does the technology handle simultaneous access requests to different FTL tables?

The patent application does not provide details on how the technology manages multiple access requests to different FTL tables.

What impact does using multiple FTL tables have on the overall performance of the memory sub-system?

The patent application does not discuss the potential performance implications of utilizing multiple FTL tables in the memory sub-system.


Original Abstract Submitted

A memory sub-system with multiple flash translation layer (FTL) tables is disclosed. A host system can utilize a memory sub-system that includes one or more memory components. The host system can provide data to be stored at the memory sub-system and can request data to be retrieved from the memory sub-system. The FTL provides several services, including translating logical addresses used by the host to physical addresses used to access physical memory. If one FTL table is corrupted, the logical-to-physical mapping of another FTL table may be used, allowing the device to continue to provide read-write access to at least a portion of the memory sub-system. Thus, by use of a secondary FTL table, the reliability of the memory sub-system is improved.
