    Abstract: A magnetic tunneling junction non-volatile register with feedback for robust read and write operations. In an embodiment, two MTJ devices are configured to store a logical 0 or a logical 1, and are coupled to drive an output node to a voltage indicative of the stored logical 0 or a logical 1. The output of a D flip-flop 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 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.

    Abstract: 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.

    CPC classification number: H03K3/59

    Abstract: Clock signals are distributed on a chip by applying an oscillating magnetic field to the chip. Local clock generation circuits including magnetic field sensors are distributed around the chip and are coupled to local clocked circuitry on the chip. The magnetic field sensors may include clock magnetic tunnel junctions (MTJs) in which a magnetic orientation of the free layer is free to rotate in the free layer plane in response to the applied magnetic field. The MTJ resistance alternates between a high resistance value and a low resistance value as the free layer magnetization rotates. Clock generation circuitry coupled to the clock MTJs senses voltage oscillations caused by the alternating resistance of the clock MTJs. The clock generation circuitry includes amplifiers, which convert the sensed voltage into local clock signals.
