Abstract
Techniques and mechanisms for handling data faults in a memory system which includes multiple integrated circuit (IC) dies, each die including a respective one of multiple memory arrays. In an embodiment, control logic monitors for a die failure of the multiple dies, and further monitors for a request to perform error correction for the multiple memory arrays. Each of the multiple memory arrays may store a respective vertical error correction code specific to data of that memory array. Another IC die may store a Bose, Ray-Chaudhuri, Hocquenghem (BCH) code of a horizontal codeword which spans the multiple memory arrays. In another embodiment, the BCH code is available to decode logic for data recovery operations in response to a die failure, where the BCH code is further available to the decode logic for error correction operations when all of the memory arrays are operative.
