    摘要: One aspect of the invention provides a novel scheme to preserve the failure state of a memory location. According to one embodiment, the data is read from a memory location in a read-destructive memory device. If the data is found to be valid (uncorrupted) it is written back to the memory location from where it was read in order to preserve it. If the data is found to be invalid (corrupted) then a failure codeword is written in the memory location to indicate a failure of the memory location. The failure codeword may be preselected or dynamically calculated so that it has a mathematical distance greater than all correctable data patterns.

    摘要: An intelligent bus bridge contained in a single integrated circuit chip along with computer systems and server systems that employ intelligent input/output subsystems. The intelligent bus bridge includes a local processor coupled for communication over a local component bus, a local memory controller that enables access to a local memory from the local component bus, and a component bus bridge that propagates accesses between the local component bus and a system component bus. The single integrated circuit chip enables dual-porting of the local memory controller without significant increases in input/output pins. A mode control input to the intelligent bus bridge indicates whether the intelligent bus bridge functions in a local master mode or a host master mode in a computer or server system.

    摘要: An integrated circuit includes a trace analyzer to sample, process and store data carried along internal or external data path of the circuit. The trace analyzer may include a multiplexer, a sampler, a formatter and a memory controller. The trace analyzer samples data on a predetermined basis, processes it and caused the processed data to be stored in a memory.
