  • Patent number: 11726062
    Abstract: In a method of testing a multilayer structure containing a magnetic layer, one or more network parameters are measured of a waveguide that is electromagnetically coupled with the multilayer structure as a function of frequency and as a function of a magnetic field applied to the multilayer structure during the measuring of the network parameters. Based on the measured one or more network parameters, at least one magnetic property of the magnetic layer of the multilayer structure is determined. The network parameters in some embodiments are S-parameters. The at least one magnetic property may include an effective anisotropy field of the magnetic layer and/or a damping constant of the magnetic layer.

  • Patent number: 11726747
    Abstract: In some embodiments, a method for generating a random bit is provided. The method includes generating a first random bit by providing a random number generator (RNG) signal to a magnetoresistive random-access memory (MRAM) cell. The RNG signal has a probability of about 0.5 to switch the resistive state of the MRAM cell from a first resistive state corresponding to a first data state to a second resistive state corresponding to a second data sate. The first random bit is then read from the MRAM cell.
