Abstract:
A nonvolatile memory system comprising:Nonvolatile memory for storing sector information, said nonvolatile memory being organized into blocks, each block including a plurality of sectors, each sector identified by a logical block address and for storing sector information; and A controller coupled to said nonvolatile memory responsive to a host for writing sector information to said nonvolatile memory and responsive to the host for updating said sector information, Wherein upon updating sector information, the controller writes to the next free or available sector(s) of a block such that upon multiple re-writes or updating of sector information, a plurality of blocks are substantially filled with sector information and upon such time, the controller rearranges the updated sector information in sequential order based on their respective logical block addresses thereby increasing system performance and improving manufacturing costs of the controller.
