Dual mode sensing scheme
A method of sensing a data value stored at a memory cell according to a dual mode sensing scheme includes determining, at a sensing circuit, whether a resistance of a magnetic tunnel junction (MTJ) element is within a first range of resistance values, within a second range of resistance values, or within a third range of resistance values. The MTJ element is included in the memory cell. The method also includes determining the data value stored at the memory cell according to a first mode of operation if the resistance of the MTJ element is within the first range of resistance values or within the third range of resistance values. The method further includes determining the data value stored at the memory cell according to a second mode of operation if the resistance of the MTJ element is within the second range of resistance values.
