Methods, apparatus, and systems to replace values in a device

A system comprising:

• a program counter to identify a first instruction to be executed, the first instruction located in a non-volatile memory at a first address;
• a replacement generator to:
• access, by a trigger controller, a set of trigger instruction address records to retrieve a trigger instruction address record;
• determine, by a trigger comparator, whether to replace a first value by comparing the first address with a second address of the trigger instruction address record;
• and
• in response to the second address corresponding to the first address:
• access, by an address accessor, a third address corresponding to the trigger instruction address record and to a location of the first value;
• access, by a value accessor, a second value corresponding to the trigger instruction address record;
• and
• replace, by a replacement executor, the first value at the third address with the second value;
• and
• an execution unit to execute a second instruction to access the second value.

A method comprising:

• accessing, by a processor, a first address corresponding to a first location in a non-volatile memory;
• accessing, by a trigger controller, a set of trigger instruction address records to retrieve a trigger instruction address record;
• determining, by a trigger comparator, whether to replace a first value by comparing the first address with a second address corresponding to the trigger instruction address record;
• accessing, by an address accessor, a third address corresponding to the trigger instruction address record and to a location of the first value;
• accessing, by a value accessor, a second value corresponding to the trigger instruction address record, the second value different than the first value;
• and
• replacing, by a replacement executor, the first value at the third address with the second value, the second value to be accessed by an instruction.
