摘要： A magnetic tunneling junction non-volatile register with feedback for robust read and write operations. In an embodiment, two MTJ devices (124; 126) are configured to store a logical 0 or a logical 1, and are coupled to drive an output node (132) to a voltage indicative of the stored logical 0 or a logical 1. The output of a D flipflop (104) is fed to the two MTJ devices so that the state of the D flip-flop may be stored in the two MTJ devices during a store operation. During a read operation, the D flip-flop outputs the state of the two MTJ devices. Read disturbances are mitigated with the use of an edge detector (134) coupled to the output node, so that a LOW voltage is provided to the D flip-flop if a rising voltage at the output node is detected.

摘要： A magnetic random access memory (MRAM) array including several bit cells is described. Each of the bit cells includes a perpendicular magnetic tunnel junction (pMTJ) -a magnetic tunnel junction with perpendicular anisotropy- including a reference layer, a barrier layer supporting the reference layer, and a free layer supporting the barrier layer. A spin-hall conductive material layer supports the free layer. A driver is operable to set a state of at least one of the plurality of bit cells, the driver being configured to simultaneously drive a current along the spin-Hall conductive material to generate via a Spin Hall effect a Spin Orbit Transfer -SOT- current flowing through the pMTJ and drive a further current through the pMTJ and a portion of the spin- hall conductive material layer, the further current generating with the reference layer a Spin-transfer-torque -STT- current through the pMTJ.

For example, a magnetic field-based contactless transmitter (32) is disclosed that includes a substrate (44), a pair of dipole coils (36A, 36B) disposed on the substrate, and a drive circuit (38) electrically coupled to the pair of dipole coils. To transmit data to a magnetic tunnel junction (MTJ) receiver (34) disposed on a second substrate (64), the drive circuit is configured to drive the pair of dipole coils so as to generate a magnetic field (HIX) in-plane to the MTJ receiver. Data can be transmitted from the magnetic field-based contactless transmitter to the MTJ receiver using the magnetic field.

摘要： Magneto-impedance (MI) sensors employing current confinement and exchange bias layer(s) for increased MI sensitivity are disclosed. MI sensors may be used as biosensors to detect biological materials. The sensing by the MI devices is based on a giant magneto-impedance (GMI) effect, which is very sensitive to a magnetic field. The GMI effect is a change in impedance of a magnetic material resulting from a change in skin depth of the magnetic material as a function of an external direct current (DC) magnetic field applied to the magnetic material and an alternating current (AC) current flowing through the magnetic material (or adjacent conductive materials). Thus, this change in impedance resulting from a magnetic stray field generated by magnetic nanoparticles can be detected in lower concentrations and measured to determine the amount of magnetic nanoparticles present, and thus the target analyte of interest.

摘要： A method and apparatus for generating random binary sequences from a physical entropy source having a state A and a state B by detecting whether the physical entropy source is in the state A or in the state B, attempting to shift the state of the physical entropy source to the opposite state in a probabilistic manner with less than 100% certainty, and producing one of four outputs based on the detected state and the state of the physical entropy source before the attempted shift. The outputs are placed in first and second queues and extracted in pairs from each queue. Random binary bits are output based on the sequences extracted from each queue.
