Classification: CPC G | IPC G

Claim 13:
14. The method of claim 13, wherein refreshing the threshold switching selectors in respective MRAM cells at the first rate and refreshing the magnetoresistive elements in the respective MRAM cells at the second rate includes for a plurality of iterations:
applying, for n times each iteration, the first signals to the particular MRAM cell to turn on the threshold switching selector in order to reset the threshold voltage of the threshold switching selector without refreshing data stored in the magnetoresistive element of the particular MRAM cell; and
applying, once each iteration, the first signals and the second signals to the particular MRAM cell to both to turn on the threshold switching selector in order to reset the threshold voltage of the threshold switching selector and to refresh data stored in the magnetoresistive element of the particular MRAM cell.
