Abstract
Designs of nonvolatile memory systems and memory operations that enable allocating reliability values associated with the hard data values from memory cells and performing an error correction operation for the hard data based on the reliability values. One example of a memory system includes a nonvolatile memory device including a plurality of memory cells, and a controller suitable for obtaining hard data by performing a hard read operation based on a hard read voltage for the memory cells, and performing an error correction operation for the hard data based on reliability values.
