ABSTRACT:
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.
