摘要： A virtualization based system comprises a host and a plurality of virtual machines that may each comprises a guest memory. A virtual machine monitor has access to underlying platform hardware in the system and may control physical resources in the platform. The platform hardware comprises a processor and a memory coupled to the processor. Further, the VMM may manage guest software including guest operating systems running on the virtual machines. A binary translation logic may replace guest memory writing instructions corresponding to a hot spot in guest application with translated codes to generate a mirrored content for the guest memory. The binary translation logic may combine one or more of the guest memory writing instructions in a region and keep the region atomic. The processor may execute the translated codes in an atomic region together to write a content in the guest memory and a mirrored content in a mirroring memory. The VMM may allocate a memory region in the host memory for the mirroring memory. The guest memory comprises one or more guest memory pages and the mirroring memory may comprise one or more mirroring memory pages. The VMM may add an offset to a virtual address of a guest memory page to obtain a virtual address of a mirroring memory page. The VMM may manage or emulate a guest page table comprising a mapping between virtual address to guest physical addresses for the guest memory. The VMM may synchronize a shadow page table with the mapping in the guest page table. The shadow page table comprises a mapping of virtual addresses to host physical addresses for the guest memory and a mapping of virtual addresses to host physical addresses for the mirroring page. Upon a memory failure in the guest memory page, the VMM may restore the content of the corrupted guest memory page from the mirroring memory page.

摘要： A nonvolatile memory element is disclosed comprising a first electrode, a near-stoichiometric metal oxide memory layer having bistable resistance, and a second electrode in contact with the near-stoichiometric metal oxide memory layer. At least one electrode is a resistive electrode comprising a sub-stoichiometric transition metal nitride or oxynitride, and has a resistivity between 0.1 and 10 Ωcm. The resistive electrode provides the functionality of an embedded current-limiting resistor and also serves as a source and sink of oxygen vacancies for setting and resetting the resistance state of the metal oxide layer. Novel fabrication methods for the second electrode are also disclosed.

摘要： Methods of annealing a thin semiconductor wafer are disclosed. The methods allow for high-temperature annealing of one side of a thin semiconductor wafer without damaging or overheating heat-sensitive electronic device features that are either on the other side of the wafer or embedded within the wafer. The annealing is performed at a temperature below the melting point of the wafer so that no significant dopant redistribution occurs during the annealing process. The methods can be applied to activating dopants or to forming ohmic contacts.
