    摘要: Multi-hit errors in a processor cache are detected by a multi-hit detection circuit coupled to the hit lines of the cache. The multi-hit detection circuit compares pairs of hit signals on the hit lines to determine if any two hit signals both indicate a hit. If multiple hits are detected, an error flag indicating the occurrence of multiple hits is generated.

    摘要: A sense amplifier may include a pair of output terminals, an evaluation circuit, a reference circuit and a pair of clamping circuits. The evaluation circuit connects a first output terminal to an evaluation potential. It receives a data signal at an input terminal. The reference circuit connects a second output terminal to the evaluation potential. The reference circuit receives a pair of reference signals on other input terminals. The clamping circuits each couple a respective one of the output terminals to a precharge potential. Inputs of each clamping circuit are coupled to the other of the output terminals.
