    摘要: A Content Addressable Memory array includes a plurality of coupled sub-blocks arranged in rows and columns. Search data received by a first sub-block in a first column of the CAM is propagated to each sub-block in the row to the last sub-block in the last column of the CAM. The search result for the CAM is selected based on the propagated search results for each row of sub-blocks and output on a side of the array opposite from the side receiving the search data.

    摘要: A circuit arrangement connects a first node to a second node. The circuit arrangement includes a first semiconductor switching element and a drive circuit. The first semiconductor switching element has a load path and a control terminal, the load path being connected between the first and second nodes. The drive circuit operably coupled to the control terminal, and is configured to detect a first voltage applied to the first node. The drive circuit is further operable to regulate the first semiconductor switching element via its control input if the first voltage reaches a first threshold value.

    摘要: A delay locked loop operates over a wide range of frequencies and has high accuracy, small silicon area usage, low power consumption and a short lock time. The DLL combines an analog domain and a digital domain. The digital domain is responsible for initial lock and operational point stability and is frozen after the lock is reached. The analog domain is responsible for normal operation after lock is reached and provides high accuracy using smaller silicon area and low power.

    摘要: A delay locked loop includes initialization circuitry that ensures that a DLL is initialized to an operating point that is not to close to either end of a delay vs. control voltage characteristic. The initialization circuitry forces the DLL to initially search for a lock point starting from an initial delay, the delay is varied in one direction, forcing the DLL to skip the first lock point. The initialization circuitry only allows the DLL to vary the delay of the voltage controlled delay loop in the one direction from the initial delay until the operating point is reached.
