Abstract: System and method for improved transferring of data involving memory device systems.

Abstract: The present invention relates to a method of transfecting cells comprising applying cells directly onto nucleic acids which are immobilized in transfection complexes on a surface and which transfect the cells. Preferably, the nucleic acids are immobilized in an array. In another aspect of the present invention, the method further includes expression of the nucleic acids in the transfected cells. In yet another aspect of the present invention, the method further comprises detecting the expression of the nucleic acids in the transfected cells.

Abstract: A plurality of processors each includes a central processor unit for processing programs at predetermined synchronization priority levels and a cache memory. A memory shared by all of the processors includes an synchronization level table which identifies a processor operating at each synchronization priority level. A common bus interconnects the processors and the memory. When a processor is to execute a program, it adjusts its synchronization priority level to a predetermined synchronization priority level by accessing the synchronization level table over the common bus to determine whether the level is accessible and, if so, places an entry in the table to indicate that the synchronization priority level is occupied. If the synchronization priority level is not accessible, the processor continually monitors the entry in the table over the common bus to determine when it is accessible by monitoring its cache, which contains a copy of the table entry associated with the synchronization priority level.
