20110157949 | Highly Efficient III-Nitride Power Conversion Circuit - According to an exemplary embodiment, a III-nitride power conversion circuit includes a gate driver having a plurality of cascaded inverters, each of the plurality of cascaded inverters including at least one III-nitride transistor. At least one of the plurality of cascaded inverters has a cutoff switch and a III-nitride depletion mode load where the cutoff switch is configured to disconnect the III-nitride depletion mode load so as to prevent current from flowing from a supply voltage of the at least one of the plurality of cascaded inverters. The cutoff switch of the at least one of the plurality of cascaded inverters can be driven by one of the plurality of cascaded inverters. The III-nitride power conversion circuit can also include an output driver driven by the gate driver where the output driver has a segmented III-nitride transistor. Furthermore, a selector circuit can be configured to selectively disable at least one segment of the segmented III-nitride transistor. | 2011-06-30 |
20110157950 | MEMORY CHIPS AND JUDGEMENT CIRCUITS THEREOF - A memory chip is provided. The memory chip operates at modes and includes an option pad and a judgment circuit. The judgment circuit is coupled to the option pad generates a judgment signal according to the current status of the option pad. The judgment signal indicates which mode the memory chip is operating at. The judgment circuit includes a detection unit and a sampling unit. The detection unit is coupled to a first voltage source and the option pad and further controlled by a control signal to generate at least one detection signal according to the current status of the option pad. The sampling unit samples the at least one detection signal after the control signal is asserted to generate the judgment signal. When the control signal is asserted, a level of the at least one detection signal is varied by a voltage provided by the first voltage source. | 2011-06-30 |
20110157951 | 3D CHIP SELECTION FOR SHARED INPUT PACKAGES - A multi-chip package with die having shared input and unique access IDs. A unique first ID is assigned and stored on die in a die lot. A set of die is mounted in a multi-chip package. Free access IDs are assigned by applying a sequence of scan IDs on the shared input. On each die, the scan ID on the shared input is compared with the unique first ID stored on the die. Upon detecting a match, circuitry on the die is enabled for a period of time to write an access ID in nonvolatile memory, whereby one of the die in the multi-chip package is enabled at a time. Also, the shared input is used to write a free access ID in nonvolatile memory on the one enabled die in the set. The unique first IDs can be stored during a wafer level sort process. | 2011-06-30 |
