  • Patent number: 11709610
    Abstract: A memory system, a memory controller and an operating method are disclosed. A first area, a second area included in the first area, and a third area are set. An area to which target data is to be written is determined to the first area or the third area. When the target data is written to the first area, the target data is preferentially written to the second area. The number of data bits stored per memory cell in the first area is less than the number of data bits stored per memory cell in the third area. As a consequence, it is possible to secure storage capacity of the memory system to at least a set reference while securing data write performance of the memory system recognized by a host to at least a set reference.
