    摘要: A memory comprises a number of word lines in a first direction, a number of bit lines in a second direction, each coupled to at least one of the word lines, and a number of memory elements, each coupled to one of the word lines and one of the bit lines. Each memory element comprises a top electrode for connecting to a corresponding word line, a bottom electrode for connecting to a corresponding bit line, a resistive layer on the bottom electrode, and at least two separate liners, each liner having resistive materials on both ends of the liner and each liner coupled between the top electrode and the resistive layer.

    摘要: An example of a capacitor includes a series of ridges and trenches and an interconnect region on the integrated circuit substrate. The series of ridges and trenches and the interconnect region have a capacitor foundation surface with a serpentine cross-sectional shape on the series of ridges and trenches. Electrical conductors are electrically connected to the electrode layers from the interconnect region for access to the electrode layers of the capacitor assembly.

    摘要: A magnetic memory device comprises a magnetic memory cell that includes a pinned layer and a free layer separated from the pinned layer by an insulating layer. The magnetic memory device also comprises a thermal plate in contact with the free layer. The magnetic memory device can be configured so that a first current flows through the thermal plate heating the thermal plate. The magnetic behavior of the free layer can be altered due to the heating caused by the first current, making it easier to switch the orientation and magnetization of the free layer. A second current can then flow through a bit line near the free layer generating a magnetic field sufficient to switch the orientation of magnetization of the free layer.
