摘要： A system and method for providing a physically unclonable function (PFU) is described. In operation, the method includes applying a domain wall shift pulse challenge to a plurality of nanowires of a domain wall memory (DWM) array, wherein the nanowires of the domain wall memory (DWM) array have process induced variations, resulting in pinning potentials which affect the velocity of the domain walls along the length of the nanowires. Following the application of the domain wall shift pulse, the response to the challenge is determined by measuring the response of the plurality of nanowires of the domain wall memory to the applied domain wall shift pulse challenge to provide a physically unclonable function (PUF) for the integrated circuit.

摘要： A semiconductor device includes a plurality of spin units individually including a memory cell configured to store values of spins in an Ising model, a memory cell configured to store an interaction coefficient from an adjacent spin that exerts an interaction on the spin, a memory cell configured to store an external magnetic field coefficient of the spin, and an interaction circuit configured to determine a subsequent state of the spin. The spin units individually include a random number generator configured to supply the random number to the plurality of the spin units and generate two-valued simulated coefficients of two values or simulated coefficients of three values in performing an interaction to determine a subsequent state of a spin of the spin units from a value of a spin from an adjacent spin unit, an interaction coefficient, and an external magnetic field coefficient.

摘要： A domain wall injector device uses electrical current passed across an interface between two magnetic regions whose magnetizations are aligned non-collinearly to create a domain wall or a series of domain walls in one of the magnetic regions. The method relies on a combination of innate fringing fields from the magnetic regions and the spin-transfer torque derived from the charge current. The device may be used to store data that are subsequently read out.

The shift register includes a plurality of rotors arranged along one direction and provided with a uniaxial anisotropy. Each of the plurality of rotors has a characteristic direction rotatable around a rotational axis extending in the one direction. The program/read element is configured to program data to the shift register by causing the characteristic direction of one of the rotors to match one selected from two directions conforming to the uniaxial anisotropy and configured to read the data by detecting the characteristic direction. The rotating force application unit is configured to apply a rotating force to the shift register to urge the characteristic direction to rotate. The plurality of rotors are organized into a plurality of pairs of every two mutually adjacent rotors. A first force acts to urge the characteristic directions to be opposingly parallel for two of the rotors belonging to the same pair. A second force acts to urge the characteristic directions to be opposingly parallel for two mutually adjacent rotors belonging to mutually adjacent pairs.

摘要： A data update system in a bubble memory in which, to preserve the simultaneity of data in the event of a power failure during the updating of data in the bubble memory, initialization data is written into a specific data storage area of the bubble memory the initialization data indicates that the data in a first data storage area is invalid, and new data is subsequently written into the first data storage area from a first record to a last record successively under the control of a bubble memory controller. The initialization data is thereby erased after the new data is completely written in the first data storage area, after which the new data, written in the first data storage area, is again written into a second data storage area from the first record to the last record thereof.
