Claim 8:
9. The system of claim 7, wherein the operations to control the retirement of the block of memory include operations to:
perform a block scan after the block of memory is closed in response to the Z-score of the second metric being greater than the threshold for Z-scores of the second metric;
determine a failed bit count for each page of the block of memory from the block scan; and
calculate, in response to the failed bit count of each page being less than a threshold for correctable error correcting code errors, a mean value and sigma value using the measured time to erase the block of memory and previous times to erase blocks of memory, the previous times associated with the Z-score of the second metric.
