Abstract
Disclosed in the present application are an operating method for a memory controller, a memory controller, a system, and an electronic device. The operating method can include, when detecting that remaining capacity of a used backup area in the memory is less than capacity required for redundancy check data to be written, determining a backup area to be used from the memory, determining valid redundancy check data belonging to garbage collection in the used backup area, and backing up the valid redundancy check data into the backup area to be used, and erasing the used backup area.
Claims21
An operating method for a memory controller that is coupled with one or more memories, the operating method comprising:
- determining a backup area to be used from the memory when detecting that remaining capacity of a used backup area in the memory is less than capacity required for redundancy check data to be written;
- determining valid redundancy check data belonging to garbage collection in the used backup area;
- and
- backing up the valid redundancy check data into the backup area to be used, and erasing the used backup area.
A memory controller that is coupled with one or more memories, the memory controller comprising a processor that is configured to:
- determine a backup area to be used from the memory when detecting that remaining capacity of a used backup area in the memory is less than capacity required for redundancy check data to be written;
- determine valid redundancy check data belonging to garbage collection in the used backup area;
- and
- back up the valid redundancy check data into the backup area to be used, and erase the used backup area.
A memory system, comprising:
- one or more memories having a memory array;
- and
- a memory controller coupled with the memory and configured to control the memory;
- wherein the memory controller comprises a processor that is configured to:
- determine a backup area to be used from the memory array when detecting that remaining capacity of a used backup area in the memory array is less than capacity required for redundancy check data to be written;
- determine valid redundancy check data belonging to garbage collection in the used backup area;
- and
- back up the valid redundancy check data into the backup area to be used, and erase the used backup area.
