In an embodiment, only one sector of a plurality of sectors in a physical block of a plurality of physical blocks has a sector status location configured to store information that indicates a move status of an other sector of the plurality sectors of the physical block of the plurality of physical blocks, where the only one sector of the plurality of sectors in the physical block of the plurality of physical blocks is configured to store a sector of data in addition to the information that indicates the move status.

Electronic system having memory with a physical block having a sector storing data and indicating a move status of another sector of the physical block

In an embodiment, a non-volatile memory has erasable blocks of memory cells. The one or more of the erasable blocks include a particular block to be identified by a particular group of logical block addresses corresponding to a predetermined group of sectors.

Memory block identified by group of logical block addresses, storage device with movable sectors, and methods

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 &#x201c;original&#x201d; physical block address and the &#x201c;moved&#x201d; physical block address and for providing information regarding &#x201c;moved&#x201d; sectors within the block being accessed.

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.
