description Systems and methods are disclosed for monitoring the time it takes to perform a write operation, and based on the time it takes, a determination is made whether to retire a block that is a recipient of the write operation. The time duration of the write operation for a page or a combination of pages may indicate whether any block or blocks containing the page or combination of pages is experiencing a physical failure. That is, if the time duration of the write operation for a particular page exceeds time threshold, this may indicate that this page requires a larger number of program cycles than other pages. The longer programming cycle can be an indication of cell leakage or a failing block.
