Method for enhancing life cycle of memory |
摘要 |
A hierarchical mechanism for preventing concentrated wear on single physical block or a specific set of physical blocks in the physical memory is proposed. The logical blocks mapping to the physical blocks in the physical memory are classified into two different levels for implicitly representing the modification times of the physical blocks. A modify count and a maximum modify count are further included for counting the modification times in a single process of the hierarchical mechanism and for limiting the modification times in single process, leading to the probabilities of all the physical blocks being modified in the physical memory being balanced. The breakdown of the physical memory caused by the breakdown of a specific set of physical blocks or single physical block is thus prevented. |
