- ENDURANCE AWARE ERROR-CORRECTING CODE ECC PROTECTION FOR NON-VOLATILE MEMORIES

摘要

embodiments of the present invention are resistant to the memory (for example, phase change memories) recognition relates to ECC protection. According to one embodiment, the method includes calculating a second metadata for ECC bits to protect the first metadata, and a data bit and the first metadata for the data bits. Embodiments may include at least a first meta-data bits, and (ECC bits for) at least one second meta data bits (for the data bits). Additional ECC protection level protects the second metadata. In one embodiment, the data bits and ECC bits applied to the wear-reducing modifications are also different and can be customized for the behavior of the bit. According to one embodiment, the present the described durability-recognition while ECC protection reduces the wear due to the access in the in the memory, the wear-reducing mechanism deals with the problem of introducing for these error detection and correction system
