ABSTRACT:
An apparatus and method for exclusively binding data to a data processing system. The logical binding apparatus of the present invention includes a detachable circuit device mounted within a system planar. Data to be bound within the system planar is stored in a memory device within the detachable circuit device. A battery signal is applied from the system planar to a binding pin on the detachable circuit device, wherein the binding pin is applied to the input of a binding latch. The binding latch remains in a reset state while the battery signal is applied. Upon removal of said binding signal from the binding pin, the binding latch is set thus signaling a processing unit within the detachable circuit device to remove the data from the memory device.
