摘要： Methods and apparatus for caching updates or new data associated with a logical block are disclosed. According to one aspect of the present invention, a method for processing contents associated with blocks of a non-volatile memory includes obtaining a first set of contents that is associated with a first group of logical pages associated with a first logical block, and writing the first set of contents into a memory area. The first set of contents is then written from the memory area into a first group of physical pages associated with a second physical block that is then mapped to the first logical block. In one embodiment, the memory area is one of a RAM cache and a physical block cache.

摘要： Methods and apparatus for allow different mapping implementations, including a many-to-one logical to physical block mapping, to be used within a memory system are disclosed. According to one aspect of the present invention, a method for mapping a plurality of logical blocks to a physical block includes identifying a first logical block meets at least one criterion. The method also includes identifying a second logical block which is substantially complementary to the first logical block, and providing contents associated with the first logical block and contents associated with the second logical block to the physical block.

摘要： Methods and apparatus for using different error correction code algorithms to encode and to decode contents of blocks within a non-volatile memory are disclosed. According to one aspect of the present invention, a method for storing data within a non-volatile memory includes identifying a first block into which the data is to be stored, and obtaining an indicator associated with the first block. A determination may then be made regarding whether the indicator indicates that the data is to be encoded using a first algorithm. The data is encoded using the first algorithm when it is determined that the data is to be encoded using the first algorithm, after which point the data encoded using the first algorithm is written into the first block.

摘要： Methods and apparatus for dynamically configuring a redundant area of a physical page are disclosed. According to one aspect of the present invention, a method for dynamically configuring a redundant area of a page associated with a physical block of a non-volatile memory of a memory system includes determining when at least one byte associated with the redundant area is to be altered. The byte includes error correction code (ECC) information associated with a first ECC algorithm at the time of the determination. The method also includes altering the byte when it is determined that the byte is to be altered. Altering the byte includes altering the byte to include ECC information associated with a second ECC algorithm.

摘要： Methods and apparatus for enabling contents to be efficiently stored in physical blocks of a non-volatile memory are disclosed. According to one aspect of the present invention, a method for performing a write operation in a non-volatile memory system which has a memory unit includes writing a first set of contents into a first physical sub-unit of the memory unit and writing a second set of contents into a second physical sub-unit of the memory unit after the first set of contents is written into the first physical sub-unit. The first physical sub-unit is sequentially before the second physical sub-unit in the memory unit. The first set of contents is associated with a second logical sub-unit of a logical unit and the second set of contents is associated with a first logical sub-unit of the logical unit that is sequentially before the second logical sub-unit in the logical unit.
