摘要： In a memory card, identification numbers identifying the memory card are permanently stored in fuse blown registers formed in each of two redrive chips, which function to read out data from memory chips of the memory card and store data in the memory chips of the memory card. Each identification number separately provides a unique identification of the memory card. The identification numbers are each stored with an error correction code by which single bit errors en the identification numbers can be corrected and the occurrence of multiple bit errors in the identification numbers can be detected. Both identification numbers, if valid, are used to identify the memory card and both of the identification numbers, if valid, are stored in association with memory quality events occurring on the memory card, so as to provide a redundant identification of the memory card on which the memory quality events occurred.

摘要： A method of automatically invoking a recoverable and fault tolerant implementation of the complemented/recomplemented (C/R) error correction method without the assistance of a service processor when an excessive error is detected in main storage (MS) by ECC logic circuits. An excessive error is not correctable by the ECC. These novel changes to the C/R method increase its effectiveness and protect the C/R hardware against random failure. Further, if an excessive error is corrected in a page in MS, an excessive error reporting process is provided for controlling the reporting using a storage map to determine if a previous correction in that page has been reported. If it has been reported, then no further reporting of soft excessive errors is made for that page. A service processor is signaled in parallel to update its persistent copy of the storage map so that on a next initializations of MS the memory map can be restored in the memory. The memory map is used to assist the repair of failing parts of MS, and is reset after MS is repaired.
