Abstract
In a nonvolatile memory array that has a binary cache formed of SLC blocks and a main memory formed of MLC blocks, corrupted data along an MLC word line is corrected and relocated, along with any other data along the MLC word line, to binary cache, before it becomes uncorrectable. Subsequent reads of the relocated data directed to binary cache.
