A method of handling a stuck bit in a directory of a cache memory which detects an error in a stored tag having an address field, a state field and an error-correction field, determines that the error is associated with a stuck bit of the directory member, marks the directory member as defective, and casts out corrected address information. The error is detected during processing of a cache directory access request, and is determined to be associated with a stuck bit of the directory member by attempting to correct a first error and then detecting a second error after the first correction attempt. The address information is cast out by routing a surrogate tag contained in a surrogate member of the cache directory through error-correction pipeline circuitry while transmitting the address information from the surrogate member to a cast-out machine.
