  • Moving sectors within a block of information in a flash memory mass storage architecture
    Patent number: 7908426
    Abstract: A device is disclosed for storing mapping information for mapping a logical block address identifying a block being accessed by a host to a physical block address, identifying a free area of nonvolatile memory, the block being selectively erasable and having one or more sectors that may be individually moved. The mapping information including a virtual physical block address for identifying an “original” location, within the nonvolatile memory, wherein a block is stored and a moved virtual physical block address for identifying a “moved” location, within the nonvolatile memory, wherein one or more sectors of the stored block are moved. The mapping information further including status information for use of the “original” physical block address and the “moved” physical block address and for providing information regarding “moved” sectors within the block being accessed.
    Type: Grant
