  • Patent number: 8008643
    Abstract: A memory device with a thin heater forms a programmable resistive change region in a sub-lithographic pillar of programmable resistive change material (“memory material”), where the heater is formed within the pillar between the top electrode and the programmable material. The device includes a dielectric material layer and vertically separated top and bottom electrodes having mutually opposed contact surfaces. A sub-lithographic pillar of memory material, which in a particular embodiment is a chalcogenide, is encased within the dielectric material layer. A heater between the pillar of programmable resistive material and the top electrode forms an active region, or programmable resistive change region, next to the heater when the memory device is programmed or reset.

  • Patent number: 8008114
    Abstract: A phase change memory device comprises a photolithographically formed phase change memory cell having first and second electrodes and a phase change element positioned between and electrically coupling the opposed contact elements of the electrodes to one another. The phase change element has a width, a length and a thickness. The length, the thickness and the width are less than a minimum photolithographic feature size of the process used to form the phase change memory cell. The size of the photoresist masks used in forming the memory cell may be reduced so that the length and the width of the phase change element are each less than the minimum photolithographic feature size.

  • Patent number: 8006177
    Abstract: Machine readable documents connect businesses with customers, suppliers and trading partners. The self defining electronic documents, such as XML based documents, can be easily understood amongst the partners. Definitions of these electronics business documents, called business interface definitions, are posted on the Internet, or otherwise communicated to members of the network. The business interface definitions tell potential trading partners the services the company offers and the documents to use when communicating with such services. Thus, a typical business interface definition allows a customer to place an order by submitting a purchase order or a supplier checks availability by downloading an inventory status report. Also, composition of the input and output documents, coupled with interpretation information in a common business library, programs the transaction in a way which closely parallels the way in which paper based businesses operate.

The method includes providing a lateral distribution of intensity values of the image at different depths with the resist. Next, the lateral position of an edge point of the feature is predicted in dependence upon a particular resist development time, and further in dependence upon the image intensity values at more than one depth within the resist.

  • Patent number: 8005152
    Abstract: A signal compression method and apparatus for a base transceiver system (BTS) in a wireless communication network provides efficient transfer of compressed signal samples over serial data links in the system. For the uplink, an RF unit of the BTS compresses baseband signal samples resulting from analog to digital conversion of a received analog signal followed by digital downconversion. The compressed signal samples are transferred over the serial data link to the baseband processor then decompressed prior to normal signal processing. For the downlink, the baseband processor compresses baseband signal samples and transfers the compressed signal samples to the RF unit. The RF unit decompresses the compressed samples prior to digital upconversion and digital to analog conversion to form an analog signal for transmission over an antenna. Compression and decompression can be incorporated into operations of conventional base stations and distributed antenna systems, including OBSAI or CPRI compliant systems.

  • Patent number: 8006300
    Abstract: Random partial shared secret recognition is combined with using more than one communication channel between server-side resources and two logical or physical client-side data processing machines. After a first security tier, a first communication channel is opened to a first data processing machine on the client side. The session proceeds by delivering an authentication challenge, identifying a random subset of an authentication credential, to a second data processing machine on the client side using a second communication channel. Next, the user enters an authentication response in the first data processing machine, based on a random subset of the authentication credential. The authentication response is returned to the server side on the first communication channel for matching. The authentication credential can be a one-session-only credential delivered to the user for one session, or a static credential used many times.

  • Patent number: 8001505
    Abstract: An electronic design automation technology merges coverage logs. The coverage logs are generated by verification of a hardware description language circuit design. The coverage logs are merged as the coverage logs are generated, without waiting for all pending coverage logs. Another electronic design automation technology also merges coverage logs. The merged coverage logs include a first coverage log of a first simulation of a hardware description language circuit design and a second coverage log of a second simulation of the hardware description language circuit design. The first simulation is based on a first hardware verification language coverage model of the hardware description language circuit design. The second simulation is based on a second hardware verification language coverage model of the hardware description language circuit design. The second hardware verification language coverage model is newer and different than the first hardware verification language coverage model.

  • Patent number: 8001498
    Abstract: A computer implemented representation of a circuit design including memory is abstracted to a smaller netlist, which can be analyzed by standard verification tools and by other tools that operate on netlists. The correctness of such systems can require reasoning about a much smaller number of memory entries than exist in the circuit design, and by abstracting such memories to a smaller number of entries, the computational complexity of the verification problem is substantially reduced.

  • Patent number: 8001172
    Abstract: An electronic filter operates as a correlator that provides a discrete approximation of an analog signal. The analog to digital conversion is integrated directly approximation calculation. An array of sample and hold circuits or single bit comparators provide outputs to a series of multipliers, the other input of which is a coefficient value of a Fourier series approximation of the desired frequency response. Each of the sample and hold circuits samples sequentially in time and holds its sample until the next cycle. Thus the sample point rotates in time through the array and each new sample is multiplied by a different coefficient. The output of the multipliers is summed for evaluation.

  • Patent number: 7996795
    Abstract: A method, a computer medium storing computer instructions performing a method, and a computer with processor and memory perform stress modeling as follows. The stress model transforms a representation of a material conversion of a first material in the integrated circuit to a second material in the integrated circuit. Prior to the material conversion the first material occupies a first space having a first boundary. After the material conversion the first material and the second material together occupy a second space having a second boundary. The first space and the second space are different. The stress model performed by the computer system transforms the representation of the material conversion of the first material to the second material into: i) the first material occupying the first space having the first boundary, and ii) a strain displacement condition of the first material. The strain displacement condition is determined by a spatial change from the first boundary to the second boundary.
