Patent ID: 7210010

Claim:
An updating system for transforming a first data image into a second data image, wherein said first image resides across k memory blocks of a block-structured non-volatile memory device contained in a client device, said updating system comprising: an update generator that produces an update package resulting from a comparison between the first data image and the second data image whereby said comparison selects and encodes an instruction set comprising a plurality of SETBLOCK, COPY and ADD operations for each of the k memory block; and an update decoder resident on the client device, whereby said update decoder interprets the instruction set of the update package and applies the update package to update the k memory block; wherein the SETBLOCK operations identify specific operations applicable to specific memory blocks and facilitate memory block updating in a non-sequential manner; wherein said update package further includes a status array comprised of at least two switchable status identifiers associated with each memory block X of k to be updated as instructed by the instruction set contained in the update package.
