  • Patent number: 9601417
    Abstract: Various aspects provide for bending a bending a lead frame of a semiconductor device package into a shape of an ā€œLā€ and mounting the package on a substrate. A horizontal portion of the bent lead-frame is about parallel with a surface of the package. A vertical portion of the bent lead frame is configured to extend the horizontal portion beyond the surface of the package. A device may be mounted between the substrate and the package.

  • Patent number: 9140745
    Abstract: In a system and method for cloud testing and remote monitoring of IC devices on a computerized test platform, the computerized test platform sends to a cloud server unit, which stores test programs corresponding respectively to different test items, a test request, which includes respective device codes of the IC devices and one (s) of the test items, via a communication network. The cloud server unit sends to the computerized test platform a test response, which includes one (s) of the test programs corresponding to the one (s) of the test items. The computerized test platform products test data corresponding to the device codes of the IC devices in response to execution of the one (s) of the test programs.

  • Patent number: 8569913
    Abstract: A technique for preventing power interruptions and extending backup power life is provided. The technique automatically prevents power interruptions in a line between a power source and a load. The technique can also extend the operating life of the power source. In one embodiment, a circuit for preventing power interruptions is provided. The circuit may include at least one arrays of capacitors, with the capacitors being arranged in parallel within an array, at least one switching elements configured to couple the at least one array of capacitors to a load, and a controller operatively coupled to the at least one switching element. The controller is configured to selectively drive the at least one switching element based on predetermined criteria.

  • Patent number: 6556476
    Abstract: A write-protected memory device has two write modes. Such memory device has many memory cells organized into pages. A normal write mode checks a one-bit flag collocated with every memory cell to see if writes are allowed. If the flag indicates a write operation to that memory cell is allowed, the flag is toggled and the cell is written. If the flag has previously been toggled, the write operation is prevented. A special write mode allows write operations to memory cells regardless of the state of the one-bit flag. The special write mode can be discerned in hardware by the loading of a register with a reprogrammable password, or the splitting of a normal single write-enable pin into two independent pins, e.g., normal write and special write.
