  • Patent number: 8670277
    Abstract: A memory includes a memory cell including a first terminal, a second terminal and a channel extending between the first terminal and the second terminal. The memory further includes an energy storage element configured to support a programming of the memory cell, the energy storage element being coupled to the first terminal, an energy supply coupled to the energy storage element, and a controller. The controller is configured to activate the energy supply and to bring the channel of the memory cell into a non-conductive state for energizing the energy storage element, and to subsequently bring the channel of the memory cell into a conductive state for programming the memory cell based on the energy stored in the energy storage element.

  • Patent number: 8293431
    Abstract: A lithographic mask comprises a first layer including grooves, a second layer including regions, sections and a groove-like structure that encloses the sections. The first and second layers are formed so as to reduce electrical potential differences within the second layer. A method of forming a lithographic mask includes forming first and second layers to dispose the second layer over the first layer, patterning the second layer to comprise sections, a region, and a groove-like structure enclosing the sections, and forming grooves in the first layer at portions not covered by the second layer. The first and second layers are formed to reduce potential differences within the second layers during the step of forming the grooves in the first layer.

  • Patent number: 7729154
    Abstract: An integrated circuit with buried control line structures. In one embodiment, the control lines are subdivided into sections, wherein regions free of switching transistors are provided at intervals along the control lines. Connections for feeding the control potentials into the sections of the control lines are provided at least in a subset of the regions free of switching transistors. The isolations lines are connected to one another by an interconnect running transversely with respect to the control lines.

  • Patent number: 7428689
    Abstract: A method for transferring data into a data memory using a data protocol is presented. The data memory is an error correction code (ECC) memory or a non-error correction code memory. The data protocol has different frames. When data are written into an ECC memory, the protocol includes a data mask frame in which the data mask bits are replaced by ECC bits. The method is designed such that ECC and non-ECC DRAMs can be established with the same protocol and at least a similar architecture.
