摘要： The disclosed invention provides a structure and method for detecting address line (e.g., wordline, bitline) memory failures. In one embodiment, the method and structure comprise generating an address signature, by re-encoding an internally generated address signal from activated elements (e.g., wordlines) inside a memory array. The regenerated address signature may be compared with a requested memory address location. If the regenerated address signature and memory location are equal than there is no error in the memory array, but if the regenerated address signature and memory location are equal than an error is present in the memory array. Accordingly, re-encoding an address signature provides a closed loop check that a wordline and/or bitline, that was actually activated in a memory array, was the correct requested wordline and/or bitline, that no other wordlines or bitlines were also triggered, and that the wordline and/or bitline is continuous.

摘要： A variable length instruction pipeline includes optional expansion stages that can be included in the variable length instruction pipeline to avoid pipeline stalls. The expansion stages are removed from the variable length instruction pipeline when not needed to reduce the length of the pipeline, which reduces latency and other problems associated with long pipelines. For example, in one embodiment of the present invention, a variable length instruction pipeline includes a first pipeline stage, a first expansion stage, and a second pipeline stage. The second pipeline stage is configured to selectively receive instructions from the first pipeline stage or the first expansion stage if the first expansion stage holds an instruction.
