  • Patent number: 7759715
    Abstract: Some embodiments include memory cells that contain a dynamic random access memory (DRAM) element and a nonvolatile memory (NVM) element. The DRAM element contains two types of DRAM nanoparticles that differ in work function. The NVM contains two types of NVM nanoparticles that differ in trapping depth. The NVM nanoparticles may be in vertically displaced charge-trapping planes. The memory cell contains a tunnel dielectric, and one of the charge-trapping planes of the NVM may be further from the tunnel dielectric than the other. The NVM charge-trapping plane that is further from the tunnel dielectric may contain larger NVM nanoparticles than the other NVM charge-trapping plane. The DRAM element may contain a single charge-trapping plane that has both types of DRAM nanoparticles therein. The memory cells may be incorporated into electronic systems.

  • Patent number: 7750408
    Abstract: Disclosed are embodiments of a circuit (e.g., an electrostatic discharge (ESD) circuit), a design methodology and a design system. In the circuit, an ESD device is wired to a first metal level (e.g., M1). An inductor is formed in a second metal level (e.g., M5) above the first metal level and is aligned over and electrically connected in parallel to the ESD device by a single vertical via stack. The inductor is configured to nullify, for a given application frequency, the capacitance value of the ESD device. The quality factor of the inductor is optimized by providing, on a third metal level (e.g., M3) between the second metal level and the first metal level, a shield to minimize inductive coupling. An opening in the shield allows the via stack to pass through, trading off Q factor reduction for size-scaling and ESD robustness improvements.

  • Patent number: 7741723
    Abstract: In a semiconductor device constituted of stacked semiconductor chips, in order to independently test each of the chips, a second chip is disposed to face a first chip, with a second interconnection terminal thereof connected to a first interconnection terminal of the first chip. First and second external terminals of the first and second chips are formed on surfaces of the first and second chips, the surface being on a same side of the first and second chips. Therefore, even after the first chip and the second chip are pasted together, it is possible to test the first chip and the second chip while operating them independently. Further, since test probes or the like can be brought into contact with the external terminals of the first chip and the second chip from the same side, it is possible to simultaneously test the first chip and the second chip.
