Abstract:
1. A method for tracking alteration of a non-volatile storage, the method comprising: receiving a request to modify a tracked region of the non-volatile storage; in response to the request, determining 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, modifying the tracked region of the non-volatile storage 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, denying the request to modify the tracked region of the non-volatile memory; and providing a configuration register which specifies a first portion of the non-volatile storage as the tracked region and a second portion of the non-volatile storage as the NEOTP alteration log region.
