  • Patent number: 11514210
    Abstract: Systems and methods for optimizing a lattice structure design are disclosed herein. In some embodiments, a method for optimizing a lattice structure design can include (i) modeling the lattice structure with a component-wise reduced-order model (CWROM) and (ii) optimizing the CWROM based on a selected criterion using a topology optimization algorithm for lattice design. The selected criterion can include a boundary condition and a load applied to the lattice structure. By modeling the lattice structure as a CWROM, the optimization process can be very fast while still permitting the accurate computation of physical quantities of the lattice structure.

  • Patent number: 10573806
    Abstract: A method of fabricating a semiconductor device includes forming a magnetic tunnel junction layer including a first magnetic layer, a second magnetic layer, and a tunnel barrier layer interposed between the first and second magnetic layers, patterning the magnetic tunnel junction layer to form a magnetic tunnel junction pattern, forming an insulating layer to cover the magnetic tunnel junction pattern, and performing a thermal treatment process to crystallize at least a portion of the first and second magnetic layers. The thermal treatment process may include performing a first thermal treatment process at a first temperature, after the forming of the magnetic tunnel junction layer, and performing a second thermal treatment process at a second temperature, which is higher than or equal to the first temperature, after the forming of the insulating layer.

  • Patent number: 7496732
    Abstract: A method and apparatus for using result-speculative data under run-ahead speculative execution is disclosed. In one embodiment, the uncommitted target data from instructions being run-ahead executed may be saved into an advance data table. This advance data table may be indexed by the lines in the instruction buffer containing the instructions for run-ahead execution. When the instructions are re-executed subsequent to the run-ahead execution, valid target data may be retrieved from the advance data table and supplied as part of a zero-clock bypass to support parallel re-execution. This may achieve parallel execution of dependent instructions. In other embodiments, the advance data table may be content-addressable-memory searchable on target registers and supply target data to general speculative execution.
