发明名称 Method for cache correction using functional tests translated to fuse repair
摘要 A method of correcting defects in a storage array of a microprocessor, such as a cache memory, by operating the microprocessor to carry out a functional test procedure which utilizes cache memory, collecting fault data in a trace array during the functional test procedure, identifying a location of the defect in the cache memory using the fault data, and repairing the defect by setting a fuse to reroute access requests for the location to a redundant array. The fault data may include an error syndrome and a failing address. The functional test procedure creates random cache access sequences that cause varying loads of traffic in the cache memory using a test pattern based on a random seed. The functional test procedure may be carried out after completion of a nonfunctional, built-in self test of the microprocessor which sets some of the fuses.
