Claim 10:
11. A method comprising:
tracking multiple metrics associated with memory operations on a memory block of one or more memory devices, each memory device including one or more memory arrays, each memory array including multiple memory blocks, each memory block arranged as a block of memory cells, each metric of the multiple metrics being a measurable event of a specified memory operation;
for each metric of the multiple metrics:
generating a Z-score for the metric; and
comparing the Z-score to a Z-score threshold for the metric, providing a comparison; and
controlling retirement of the memory block based on the comparisons and a comparison of a parameter to a parameter threshold, the parameter associated with the metric of at least one of the multiple comparisons.
