Claim:
1. A non-volatile memory system, comprising: a plurality of memory cells and a plurality of control lines arranged as a non-volatile memory structure; and a control circuit in communication with the non-volatile memory structure, the control circuit configured to cause testing of a first portion of the non-volatile memory structure for leakage in response to a successful programming process for the first portion of the non-volatile memory structure, and wherein: the control circuit is configured to cause data to be copied from the first portion of the non-volatile memory structure to a second portion of the non-volatile memory structure in response to determining that the first portion of the non-volatile memory structure has more than a first, non-zero amount of leakage and less than a second amount of leakage based on the testing; and the control circuit is configured to perform a data recovery process on data from the first portion of the non-volatile memory structure in response to determining that the first portion of the non-volatile memory structure has-more than the second amount of leakage based on the testing.
