    • A CAM (content addressable memory) device capable of flexibly coping with a wide range of user requirements with respect to operation speed and/or power consumption has operation mode setting means, generates a higher or lower internal voltage than an external power-supply voltage depending on the setting, and at least part of the internal circuit is operated by the internal voltage. In particular, the high level of the search-bit line and/or the high level of the match line are preferably set to the internal voltage. Also, the CAM device has bit line amplitude adjusting means for adjusting the amplitude of the bit line depending on the setting of the operation mode setting means and/or match line amplitude adjusting means for adjusting the amplitude of match line on which a search result is output, and thus is capable of appropriately changing the operation speed and power consumption depending on the setting.
    • 能够灵活应对各种用户对运行速度和/或功耗的要求的CAM(内容可寻址存储器)装置具有操作模式设定装置,产生与外部电源电压相关的更高或更低的内部电压 在该设置上,并且至少部分内部电路由内部电压操作。 特别地,优选地将搜索位线的高电平和/或匹配线的高电平设置为内部电压。 此外,CAM装置具有位线幅度调整装置,用于根据操作模式设定装置的设定调整位线的幅度和/或匹配线幅度调整装置,用于调整搜索结果为 输出,因此能够根据设定适当地改变操作速度和功耗。
