Abstract
A circuit generally comprising a first memory, a second memory and a processor is disclosed. The first memory may store an instruction to read an updated security value of at least three security values. The second memory may store (i) the updated security value and (ii) information related to security of the circuit. The processor may be configured to (i) execute the instruction while a register stores a highest security value of the security values, (ii) copy the information from the second memory to a third memory in response to the update security value being greater than a current security value of the security values stored in the third memory and (iii) ignore the information in the second memory in response to the updated security value being no greater than the current security value.
