A content addressable memory having a main array including a plurality of columns of CAM cells, a spare column of CAM cells selectable to functionally replace a defective column of CAM cells in the main array, and circuitry to shift data corresponding to the defective column and data corresponding to all subsequent columns to corresponding adjacent non-defective columns. An inductor body is formed around the inductor coil and includes a resin and a magnetic material compressed while it is dry and surrounding the inside and the outside of the coil. If there is not enough resources to satisfy the requirements of Group Join messages, then it may either be ignored, or queued for later processing, once the normal GSQ sequence is complete and resources are available. When the modular arm is rotated, the arm segments displace the lock bars to lock or unlock the drawers of the cabinet.
