Abstract

A method for tracking alteration of a non-volatile storage includes receiving a request to modify a tracked region of the non-volatile storage. In response to the request, it is determined whether or not a modification of data stored in a non-erasable one-time programmable (NEOTP) alteration log region has occurred. In response to determining that the modification of the data stored in the NEOTP alteration log region has occurred, the tracked region of non-volatile storage is modified in response to the request. In response to determining that the modification of the data stored in the NEOTP alteration log region has not occurred, the request to modify the tracked region of the non-volatile memory is denied.
