  • Publication number: 20100115246
    Abstract: An improved system and method of data partitioning for parallel processing of dynamically generated application data is provided. An application may send a request to partition the application data specified by a data partitioning policy and to process each of the data partitions according to processing instructions. The data partitioning policy may be flexibly defined by an application for partitioning data any number of ways, including balancing the data volume across each of the partitions or partitioning the data by data type. Asynchronous data partition processors may be instantiated to perform parallel processing of the partitioned data. The data may be partitioned according to the data partitioning policy and processed according to the processing instructions. And the results may be returned to the application.

  • Publication number: 20070241411
    Abstract: The present invention relates to a semiconductor device comprising at least one static random access memory (SRAM) cell with self-aligned contacts. Specifically, the at least one SRAM cell comprises at least a first gate conductor that is located over a channel region between a source region and a drain region. The first gate conductor is covered by a dielectric cap comprising a protective dielectric material, and the source and drain regions are covered by non-protective dielectric material(s) that can be selectively removed against the protective material. In this manner, a self-aligned source or drain contact can be formed through the non-protective dielectric material(s) to contact either the source or the drain region, while the dielectric cap protects the first gate conductor during formation of the source or drain contact opening and thereby prevents shorting between the first gate conductor and the source or drain contact to be formed.

  • Publication number: 20070211527
    Abstract: A system and method for automatically adjusting one or more electrical parameters in a memory device, e.g., SRAM arrays. The system and method implements an SRAM sensing sub-array for accelerated collection of fail rate data for use in determining the operating point for optimum tradeoff between single event upset immunity and performance of a primary SRAM array. The accelerated fail rate data is input to an algorithm implemented for setting the SEU sensitivity of a primary SRAM memory array to a predetermined fail rate in an ionizing particle environment. The predetermined fail rate is maintained on a real-time basis in order to provide immunity to SEU consistent with optimum performance.

  • Publication number: 20070164365
    Abstract: A single stress liner is applied over different type semiconductor devices. The single stress liner avoids the problems of a dual/hybrid stress liner scheme by eliminating the meeting area. The single stress liner may be tensile or compressive. In one embodiment, the semiconductor device includes a static random access memory (SRAM) cell having numerous NFETs and PFETs. In this case, a compressive liner is placed over the SRAM cell, which is normally not ideal for the NFETs therein, but is desirable for the SRAM cell because continued miniaturization of the SRAMs typically requires slowing of the NFETs for the SRAM to maintain stabile. Where SRAM cells require increased speed, a single tensile stress liner can be implemented.

  • Publication number: 20070118828
    Abstract: A reduction in the intersection of vias on the last layer (“VL”) and holes in the last thin metal layer (“MLHOLE”) can be achieved without degrading product yield or robustness or increasing copper dishing.

  • Publication number: 20050073874
    Abstract: Methods for designing a 6T SRAM cell having greater stability and/or a smaller cell size are provided. A 6T SRAM cell has a pair access transistors (NFETs), a pair of pull-up transistors (PFETs), and a pair of pull-down transistors (NFETs), wherein the access transistors have a higher threshold voltage than the pull-down transistors, which enables the SRAM cell to effectively maintain a logic “0” during access of the cell thereby increasing the stability of the cell, especially for cells during “half select.” Further, a channel width of a pull-down transistor can be reduced thereby decreasing the size of a high performance six transistor SRAM cell without effecting cell the stability during access. And, by decreasing the cell size, the overall design layout of a chip may also be decreased.
