Abstract
Embodiments are disclosed for a system that includes a data scrubbing circuit, a magnetoresistive random access memory (MRAM) having a memory array, and an analog persistent vital information circuit (APVIC) that performs a method. The method includes resetting weights corresponding to blocks of the memory array. The method further includes adjusting the weights based on a timer, data accesses on the memory blocks, and weight change values corresponding to the weights. The method also includes determining, in response to the timer, a data scrubbing threshold based on ambient temperature and magnetic field strength. The method additionally includes determining one of the weights meets the data scrubbing threshold. Further, the method includes providing, in response to the determination, an indication that a data scrubber, scrub one of the memory blocks corresponding to the weight that meets the data scrubbing threshold. Also, the method includes resetting the weight.
