OPERATION METHOD OF STORAGE CONTROLLER FOR NONVOLATILE MEMORY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18512613 titled 'OPERATION METHOD OF STORAGE CONTROLLER FOR NONVOLATILE MEMORY DEVICE
Simplified Explanation
The operation method of a storage controller involves controlling a nonvolatile memory device by performing reliability operations on memory blocks to detect degradation levels and selectively skip or perform operations based on the degradation level.
- The method includes initiating reliability operations for memory blocks, detecting degradation levels, and setting skip reference values.
- It involves determining if the number of consecutively skipped operations is less than the skip reference value.
- The method selectively skips or performs the next operation based on the determination result.
Potential Applications
This technology can be applied in:
- Data storage systems
- Solid-state drives
- Embedded systems
Problems Solved
This technology helps in:
- Improving the reliability of nonvolatile memory devices
- Extending the lifespan of memory blocks
- Enhancing data integrity
Benefits

- Reduced risk of data loss due to degradation
Potential Commercial Applications
The potential commercial applications of this technology include:
- Data centers
- Consumer electronics
- Automotive industry
Possible Prior Art
One possible prior art for this technology could be the use of wear leveling algorithms in flash memory devices to distribute write and erase cycles evenly across memory blocks.
What are the specific reliability operations performed on memory blocks?
The specific reliability operations involve detecting degradation levels and setting skip reference values based on the detected levels.
How does selectively skipping or performing operations based on degradation levels improve the overall performance of the storage controller?
By selectively skipping or performing operations, the storage controller can optimize the use of memory blocks, extending their lifespan and improving data integrity.
Original Abstract Submitted
An operation method of a storage controller, which is configured to control a nonvolatile memory device, includes initiating a first instance of a respective reliability operation for a respective memory block included in the nonvolatile memory device, the respective reliability operation including detecting a degradation level of the respective memory block and setting a respective skip reference value based on the detected degradation level; determining whether a respective number of consecutively skipped instances of the respective reliability operation is less than the respective skip reference value; and selectively skipping or performing a next instance of the respective reliability operation based on the determination result.
