Abstract: A computer system stores metadata that is used to identify physical memory devices that store randomly-accessible data for memory of the computer system. In one approach, access to memory in an address space is maintained by an operating system of the computer system. Stored metadata associates a first address range of the address space with a first memory device, and a second address range of the address space with a second memory device. The operating system manages processes running on the computer system by accessing the stored metadata. This management includes allocating memory based on the stored metadata so that data for a first process is stored in the first memory device, and data for a second process is stored in the second memory device.

Abstract: The invention belongs to the field of electronic ceramics and its manufacturing, in particular to the modified NiO-Ta2O5-based microwave dielectric ceramic material sintered at low temperature and its preparation method. It is guided by ion doping modification, not only considering the substitution of ions with similar radius, such as Zn2+ replacing Ni2+ ions, V5+ replacing Ta5+ ions; Meanwhile, the selected doped oxide still has the property of low melting point.

Abstract: A temperature-stable modified NiO—Ta2O5-based microwave dielectric ceramic material and a preparation method thereof are provided. Using ion doping modification to form solid solution structure is an important measure to adjust microwave dielectric properties, especially the temperature stability. Based on formation rules of the solid solution, ion replacement methods are designed including Ni2+ ions are replaced by Cu2+ ions, and (Ni1/3Ta2/3)4+ composite ions are replaced by [(Al1/2Nb1/2)ySn1-y]4+ composite ions, which considers that cations with similar ionic radii to Ni2+ and Ta5+ ions can be introduced into the NiTa2O6 ceramic for doping under the same coordination environment (coordination number=6), and therefore a ceramic material with the NiTa2O6 solid solution structure can be obtained. The microwave dielectric ceramic material with excellent temperature stability and low loss is finally prepared by adjusting molar contents of each of doped ions, and its microwave dielectric properties are excellent.
