    摘要: An integrated circuit includes a plurality of switching devices, wherein each device includes a gate dielectric capable of assuming at least a first and a second polarization state. The integrated circuit further includes an address circuit configured to control bit lines electrically coupled to first load regions of a load path of the switching devices and a word line electrically coupled to gate electrodes of the switching devices. The address circuit is configured to control a write cycle such that a first voltage is induced at the gate dielectrics of selected ones of the switching devices and a second voltage is induced at the gate dielectrics of non-selected ones of the switching devices. The first voltage suffices to switch the gate dielectrics of the selected devices from the first to the second polarization state and the second voltage does not suffice to switch the gate dielectrics of the non-selected devices.

    摘要: An integrated circuit includes: a resistive memory having an array of resistive memory cells; a memory controller that controls operation of the resistive memory in accordance with external commands from an external device; and a memory scheduler coupled to the resistive memory and to the memory controller. The memory scheduler schedules internal maintenance operations within the resistive memory in response to trigger conditions indicated by at least one sensor signal or external command. The operation of the memory scheduler and performance of the internal maintenance operations are transparent to the external device and, optionally, transparent to the memory controller.

    摘要: A method is described for fabricating a DRAM memory cell, which includes a trench capacitor and a select transistor. After the capacitor trench has been etched and optionally the first capacitor electrode has been produced, the trench is filled with a dummy filling. After the gate electrode and the first and second source/drain regions have been provided, the dummy filling is removed, and the capacitor dielectric and the second capacitor electrode are provided. As a result, it is possible to use temperature-sensitive materials for the capacitor dielectric and the second capacitor electrode despite the use of high-temperature steps. In the memory cell arrangement formed by this method, the direction of the conductive channel, which connects first and second source/drain regions to one another, can differ from the direction of the bit lines and of the word lines (e.g., by 45°).

    摘要: In DRAM memory cells, individual memory cells are isolated from one another by an isolation trench (STI). In such a case, a vertical transistor is formed by the isolation trench as SOI transistor because its channel region is isolated from a substrate by the isolation trench. A vertical transistor that is used, for example, in a DRAM memory cell and a method for making the transistor includes connecting the channel region of the vertical transistor to the substrate by disposing a conductive layer in the isolation trench between a lower insulation filling and an upper insulation filling.

    摘要: The memory cell has a trench in which a capacitor is formed. Furthermore, a vertical transistor is formed in the trench, above the trench capacitor. The doping regions of the vertical transistor are arranged in the substrate. In order to connect the gate electrode of the vertical transistor to a word line, a dielectric layer having an inner opening is arranged in the trench, above the gate electrode. The dielectric layer is configured as lateral edge webs which project beyond the cross section of the trench and thus cover part of the substrate. The lateral edge webs enable self-aligned formation of an isolation trench.
