Claim Text:
1. A method for writing data to a state in a thermally assisted magnetoresistive random access memory device (TAS-MRAM), the method comprising: setting a magnetic orientation of a storage layer to a position for storing the state, wherein the storage layer has an anisotropic axis, and wherein the position of the magnetic orientation includes off axis positions and on axis positions relative to the anisotropic axis; reading the state in the storage layer to obtain a first resistance value and a second resistance value of the storage layer; comparing the first resistance value and the second resistance value to predetermined resistance values of the storage layer; when the first resistance value and the second resistance value are different from the predetermined resistance values during the setting of magnetic orientation of the storage layer to the position for storing the state, resetting the magnetic orientation of the storage layer to the position for storing the state so that the first resistance value and the second resistance value are within a tolerance of the predetermined resistance values; when the first resistance value and the second resistance value match the predetermined resistance values within the tolerance in response to the resetting to the position, verifying that the predetermined resistance values have been met by the first resistance value and the second resistance value, and subsequently storing the state.
