Abstract
Embodiments of the disclosure are drawn to apparatuses and methods for content addressable memory (CAM) cells. Each CAM cell may include a comparator portion which stores a bit of information. Each CAM cell may also include a comparator portion, which compares an external bit to the stored bit. A group of CAM cells may be organized into a CAM register, with each CAM cell coupled in common to a signal line. Any of the CAM cells may change a voltage on the signal line if the external bit does not match the stored bit.
