  • Method And System For Local Data Sharing
    Publication number: 20110066813
    Abstract: Embodiments for a local data share (LDS) unit are described herein. Embodiments include a co-operative set of threads to load data into shared memory so that the threads can have repeated memory access allowing higher memory bandwidth. In this way, data can be shared between related threads in a cooperative manner by providing a re-use of a locality of data from shared registers. Furthermore, embodiments of the invention allow a cooperative set of threads to fetch data in a partitioned manner so that it is only fetched once into a shared memory that can be repeatedly accessed via a separate low latency path.

  • Increased reliability for a contact structure to connect an active region with a polysilicon line
    Patent number: 7906815
    Abstract: By forming a direct contact structure connecting, for instance, a polysilicon line with an active region on the basis of an increased amount of metal silicide by removing the sidewall spacers prior to the silicidation process, a significantly increased etch selectivity may be achieved during the contact etch stop layer opening. Hence, undue etching of the highly doped silicon material of the active region would be suppressed. Additionally or alternatively, an appropriately designed test structure is disclosed, which may enable the detection of electrical characteristics of contact structures formed in accordance with a specified manufacturing sequence and on the basis of specific design criteria.
