  • Patent number: 9613675
    Abstract: A method includes performing a memory operation at a magnetic tunnel junction (MTJ) storage element by, during a single memory clock cycle, reading a first value stored at the MTJ storage element, comparing the first value to a second value to be stored at the MTJ storage element, and selectively writing the second value to the MTJ storage element based on the comparison.
    Type: Grant

  • Patent number: 9430407
    Abstract: A machine state vector is received at a memory. The machine state vector has a machine state and a machine identifier. Write access qualification is met if the machine state entry is an initial write, or if the machine identifier matches the machine identifier of a stored machine state vector, and machine identifier and machine state are stored in the memory. A fetch machine state request is received, having a requestor machine identifier. A machine state retrieval qualification is met by the requestor machine identifier matching the stored machine identifier, and the machine state is retrieved.

  • Patent number: 9411745
    Abstract: Methods, devices, and instructions for performing a reverse translation lookaside buffer (TLB) look-up using a physical address input, including obtaining with a first processor the physical address input, wherein the physical address input indicates a physical address corresponding to a shared memory, obtaining a first mask associated with a first virtual address from a first TLB entry within a TLB associated with the first processor, wherein the obtained first mask is a bit pattern, obtaining from the first TLB entry a first page frame number associated with the shared memory, applying the obtained first mask to the obtained first page frame number to generate a first value, applying the obtained first mask to the obtained physical address input to generate a second value, and comparing the first value and the second value to determine whether the first value and the second value match.

  • Patent number: 9349692
    Abstract: A stacked integrated circuit includes a first tier IC and a second tier IC. Active faces of the first tier IC and the second tier IC face each other. An interconnect structure, such as microbumps, couples the first tier IC to the second tier IC. An active portion of a voltage regulator is integrated in the first semiconductor IC and coupled to passive components (for example a capacitor or an inductor) embedded in a packaging substrate on which the stacked IC is mounted. The passive components may be multiple through vias in the packaging substrate providing inductance to the active portion of the voltage regulator. The inductance provided to the active portion of the voltage regulator is increased by coupling the through via in the packaging substrate to through vias in a printed circuit board that the packaging substrate is mounted on.
