Abstract

See full text

Data stored in a nonvolatile memory is selectively sampled based on write-erase cycle counts of blocks. Blocks with the lowest write-erase cycle counts are sampled to determine an error rate which is compared with a limit. If the error rate exceeds the limit then the sample is expanded to include blocks with the next lowest write-erase cycle counts.
