摘要：An apparatus and method for protecting a computer system from arrayreliability failures uses Array Built-In Self-Test logic along with code and hardware todelete cache lines or sets that are defective, identify corresponding fuse repair values,proactively call home if spare fuses are not available, schedule soft fuse repairs for thenext system restart, schedule line deletes at the next restart, store delete and fuserepairs in a table (tagged with electronic serial id, timestamp of delete or ABIST failevent, address, and type of failure) and proactively call home if there were any misseddeletes that were not logged. Fuse information can also be more permanently storedinto hardware electronic fuses and/or EPROMs. During a restart, previous repairs are ableto be applied to the machine so that ABIST will run successfully and previous deletes tobe maintained with checking to allow some ABIST failures which are protected by the linedeletes to pass.
