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

摘要

The embodiment of the present invention is related to the ECC known protections non-volatile storage (for example, phase transition storage). According to one embodiment, a kind of method includes calculating the first metadata and the second metadata ECC data bit to protect data bit, these bits and the first metadata. Embodiment may include the data bit (bit) of one or more first metadata and the ECC bits (bit) of one or more second metadata. Additional ECC protections the second metadata of protection. In one embodiment, it is different from ECC applied to data bit to reduce modification for abrasion, and is suitably adapted for the bit. According to one embodiment, the ECC protections that durability is known reduce abrasion, since the error detection and correction mechanism for accessing to memory while addressing complication reduction abrasion described herein is introduced into system.
